Grid Registration

Grid Registration (German: Netzanmeldung) is the paperwork that tells the local grid operator (the Verteilnetzbetreiber, or VNB) about a new generation or load asset on their network so they can authorise the connection. In Germany it is mandatory for every PV system, battery storage upgrade, heat pump, and wallbox that connects to the public grid. Reonic offers this as a paid Service in Germany, Italy, and Brazil: you submit the filing through the Portal, and Reonic handles the VNB correspondence (the inquiry round, the document corrections, the Marktstammdatenregister entry) until the Einspeisezusage arrives. All three countries are billed weekly, each with its own free quota. Other countries are filed outside the Portal.

This guide walks the whole flow on one page: when to use the Service, what to prepare, how to file Step 1 (paperwork) and Step 2 (commissioning), how to respond when the VNB asks questions, how billing works, and what is different in Italy and Brazil.

Before you start

• Country first. Grid Registration works differently per country. Germany has the full two-step flow (workflow, billing, add-ons). Italy is a single-step paid filing. Brazil is a paid filing that Reonic moves through a staged workflow. Countries outside Germany, Italy, and Brazil do not have a Grid Registration tab today; installers there file outside the Portal.
• The Service is residential only. It lives inside the residential installation phase. Large commercial or industrial assets are filed outside the Portal.
• It is installer-managed, not customer-managed. The end customer signs a Vollmacht (power-of-attorney) authorising you and Reonic to file on their behalf. The customer never sees the Portal.
• You need the right access. Account managers and installer admins with the editor role (or higher) and the Grid Registration user-right enabled. Field workers using the Mobile App have no surface here: all photo capture and submission happen in the web Portal.
• The Service is filed on installation, not pre-sale. The filing references a planned installation, so you file once the installation is planned rather than pre-emptively on a deal. In Reonic the Vorabanmeldung (advance registration) is the Step-1 paperwork submission itself; there is no earlier intent-only filing.
• Find it inside the project. Open the project in the Portal, switch to the Installation phase, then open the Grid Registration tab. The tab appears only when your workspace is enabled for Grid Registration in Germany, Italy, or Brazil.

When to use this Service vs. file yourself

Use Reonic's Grid Registration Service when:

• You want to delegate the VNB paperwork grind to a team whose full-time job is filing them.
• You do not want to keep a master-electrician on staff or burn hours on Stromnetz Berlin, Westnetz, or Bayernwerk portals.
• Your install volume justifies the per-filing fee (see Pricing below).
• You want the Marktstammdatenregister entry (MaStR / MSD) handled in the same flow as a single add-on.

File it yourself when:

• The installation is in a country Reonic does not cover.
• Your own in-house master-electrician files directly. Only installations handled by an external electrician flow through Reonic.
• The asset is commercial rather than residential.
• You already have an Einspeisezusage in hand for the same asset (you would be paying for paperwork the VNB has already accepted). In that case skip Step 1 and start with Step 2 commissioning paperwork, or ask your Reonic account manager about a discounted post-Einspeisezusage filing.

Pricing

Germany is a paid Service. Your prices are set for your workspace, and your admin or your Reonic account manager can confirm your exact figures. Typical items:

• **PV grid registration* — One per filing. Covers the whole German PV lifecycle (Step 1 paperwork, unlimited VNB inquiry rounds, Step 2 commissioning, Einspeisezusage*).
• **Heat-pump grid registration** — One per filing. Same lifecycle for heat-pump installations, with a simpler form and a lower fee.
• **Wallbox add-on** — Add-on bundled into a PV or heat-pump filing when a wallbox is part of the same install.
• **Marktstammdatenregister add-on** — Add-on for the MaStR / MSD national-registry entry (the German PV asset registry).
• **PV free quota** — The first filings each period are free; the rest are billed at the standard fee. Set in your contract.
• **Heat-pump free quota** — A separate quota from PV. The two counters do not pool.

Pro tip: Add-ons are billed even on free filings. A free PV filing with a wallbox add-on still generates a wallbox line on the invoice. The free quota covers the base fee only.

Your exact prices and free quotas are set for your workspace; your admin or your Reonic account manager can confirm them. The German Grid Registration fee is per filing. The BzA (Bestätigung zum Antrag) is part of the KfW subsidy flow (a separate Service) and is priced separately. See Subsidy in this same Deep Dive section.

Italy is a paid Service billed per filing (the Pratica GSE base fee), invoiced weekly with your free quota applied first. The form also shows an optional ENEA enrolment toggle labelled "Pratica ENEA". Whether ticking it adds to your fee depends on your billing setup, so confirm with your Reonic account manager.

Brazil is a paid Service billed per filing (Brazilian reais), invoiced weekly with your free quota applied first.

What is included in the registration package

When you file a Germany Grid Registration through Reonic, the per-filing fee covers:

• The Step-1 paperwork submission to the VNB.
• Unlimited correction rounds. If the VNB sends an inquiry (Rückfrage), you respond as many times as needed at no additional charge.
• The Step-2 commissioning submission (the post-install meter, photos, and capacity that trigger the Einspeisezusage).
• Reonic's handling of the filing as it moves through the VNB process.

Charged separately:

• The Marktstammdatenregister (MaStR) entry: a separate add-on, ticked at filing time if you want it included.
• The wallbox add-on, ticked separately.
• The KfW subsidy filing and the BzA (Bestätigung zum Antrag): a different Service entirely (see Subsidy).

Note: Grid operators enforce a 6-month deadline for Step 2 after the physical install. Track this deadline yourself so you submit Step 2 in time.

Required documents and information

For a Germany PV filing, have these ready before opening Step 1:

• Vollmacht (power-of-attorney) signed by the customer. The customer signs a one-page form authorising you and Reonic to act on their behalf with the VNB. Without it, you can save a draft but cannot submit. It is the standard customer power-of-attorney for the VNB, signed personally by the registered owner of the meter location, including the customer's full name, address, and the meter location. You upload it into the Vollmacht slot on the form. The underlying VNB requirements come from the operator.
• Customer identity data. Name, address, contact information, and your internal customer ID. The form also captures the customer's date of birth and ID number when the VNB asks for them.
• Meter photo. Current state of the existing meter, with a clear shot of the meter number and the meter cabinet.
• Project planning file. Typically the as-planned PV layout from your planning step, exported as a PDF.
• Technical specs of the planned system. Module model, inverter model, total kWp, and battery storage details if any. These come from the planning step.
• Bestätigung zum Antrag (BzA), if a KfW subsidy is involved. The BzA is a separate document tied to the KfW subsidy flow, not the Grid Registration filing. Reonic supports residential BzA today; for commercial (gewerblich) BzA, confirm availability with your account manager. A KfW filing needs the customer's KfW application confirmation plus the project-planning document; the BzA is generated automatically once the planning is complete. See Subsidy for how to request and file the BzA and the full document set.

For Italy, the form requires 3 mandatory documents (out of 8 slots): a recent utility bill, the customer power-of-attorney, and a customer ID document. The exact set surfaces in the form itself when you open it.

For Brazil, you need installer data (CPF/CNPJ), customer data (PJ for Pessoa Jurídica / business or PF for Pessoa Física / individual, with the matching CPF or CNPJ), the customer-signed power-of-attorney, datasheets for the modules and inverter, the voltage class and circuit-breaker type, beneficiary UC numbers (Unidade Consumidora / utility customer IDs), and the installation photos.

Pro tip: The customer ID, your internal reference for the installation, is the lookup key for the VNB correspondence. Set it correctly at the start; changing it later requires help from Reonic support.

Meter requirements (Zähler, Smart Meter, Zwei-Richtungs-Zähler)

The German VNB world has specific meter requirements. The Grid Registration filing surfaces them as a prompt, and you are responsible for matching them on-site.

• *Two-way meter (Zwei-Richtungs-Zähler).* PV with feed-in needs a meter that counts both consumption and feed-in. The VNB swaps a one-direction meter for a two-way meter when it processes the filing (timing varies by VNB, often 4–8 weeks).
• *Smart meter (intelligentes Messsystem). Required above certain thresholds (currently 7 kWp PV or 25 kW load by national law, subject to change). For systems below the threshold, a modern modernes Messeinrichtung* meter is acceptable. The VNB decides which device class to install; you note the requirement and they execute.
• Zwischenzähler / sub-meter. Optional, used for heat-pump tariff measurement so the customer gets the cheaper Wärmestromtarif. Not part of the Grid Registration filing, but worth coordinating with the VNB at the same time.
• Meter location. State the meter location precisely: building name plus room (e.g. Keller, links neben dem Eingang). The VNB needs this for the installation visit. The Step-1 form captures it as a free-text field. If the meter is in a shared utility room used by multiple parties, note that explicitly.

Note: If a filing is rejected because a registration request already exists for the same meter under a different email address, another party (often the customer themselves, a previous installer, or another planning company) has already submitted a request for that meter to the VNB. Resolve it by contacting the VNB to withdraw the earlier request, or by submitting under the email used originally.

File a Germany PV grid registration (Step 1: Paperwork)

This is the most common German flow.

1. Open the project in the Portal.
2. Switch to the Installation phase.
3. Open the Grid Registration tab. The German PV form opens at the Step 1: Paperwork sub-tab. Confirm the installation is set to the external-electrician type. (If it is set to your own in-house electrician, your master-electrician is filing and Reonic is not involved.)
4. Fill the customer data section. Pull the customer from CRM if already linked; otherwise enter manually.
5. Upload the 3 mandatory files: the Vollmacht (customer-signed power-of-attorney), the meter photo (current state of the meter), and the project planning file (the as-planned PV system).
6. Optionally upload up to 3 supporting photos or documents in the optional slots (extra meter angles, EVU-specific forms, a signed cover letter).
7. Tick the wallbox add-on if a wallbox is part of the same installation. This adds the wallbox fee on top of the base fee.
8. Tick the Marktstammdatenregister (MaStR / MSD) add-on to have Reonic handle the national registry entry. This adds the MaStR fee on top.
9. Click Save as draft at any point to come back later; the record stays in your workspace until you click Submit.
10. When everything is complete, click Submit. The filing is stamped as submitted and sent to the VNB. The Submit button then greys out so you can't re-file the same registration by accident. If the submission doesn't go through, the button becomes an Erneut übertragen (re-transmit) retry: fix any flagged issue and re-transmit.

After you submit, VNB responses appear in the filing as they come in.

Pro tip: The German form header has a Brauchst du Hilfe? (Need help?) button. It opens a Reonic Service contact for grid registration plus a booking link for a short intro call. Use it when a filing is blocked or you are unsure which document a VNB wants.

The three possible outcomes:

• Accepted. The VNB approves the filing as-is. Wait for the Einspeisezusage to arrive (typically days to weeks; varies widely by VNB).
• *Inquiry (Rückfrage). The VNB asks for more info or a correction. You see an in-app banner reading "Neue Rückfrage" and a message in the filing's chat panel. Respond: see Respond to a VNB inquiry* below.
• Rejected. The VNB rejects the filing and it is archived. You may need to start fresh depending on the rejection reason.

File a Germany heat-pump grid registration

The heat-pump flow is structurally the same as PV but with a simpler form (fewer photos, simpler technical specs) and a lower fee.

1. Open the project, switch to Installation > Grid Registration.
2. The heat-pump form opens. Confirm the installation is set to the external-electrician type.
3. Fill customer data plus heat-pump specs (model, thermal output, mounting location, electrical connection).
4. Upload the 3 mandatory files: the same Vollmacht, meter photo, and project planning trio.
5. Submit. The heat-pump fee is lower than PV. Same process, same VNB correspondence flow.

When a PV system and a heat pump are part of the same installation, file them as separate Grid Registration filings: one PV, one heat pump. They are independent records, billed independently.

Step 2: Commissioning paperwork

After the physical installation is complete, file Step 2: the post-install capture that triggers the Einspeisezusage.

1. Open the same filing in the Portal Grid Registration tab.
2. Switch to the Step 2: Commissioning sub-tab (next to Step 1: Paperwork).
3. Upload the post-install photos (typically 16 or more; the exact set depends on what the VNB wants): module installation photos (multiple angles), the inverter installed, the meter installation or replacement, the cabling and circuit-breaker panel, and the SLS (Selektive Leitungsschutzschalter) installed.
4. Fill the commissioning date (when the system was switched on).
5. Fill the capacity (installed kWp / kW).
6. Fill the meter number (the new meter ID, typically the meter the VNB swapped in).
7. Pick the SLS rating.
8. Pick the commissioning system: the VNB retains remote shutoff, or the inverter throttles feed-in to zero.
9. Click Submit Step 2. The filing moves to Einspeisezusage erhalten (feed-in permission received), and the customer's system is legally cleared to feed into the grid.

Pro tip: The SLS rating and commissioning system are decisive for the VNB's final acceptance. Choose the zero-feed-in throttle when the system exceeds local feed-in limits, so energy goes only to self-consumption and battery. Choose the remote-shutoff option when the VNB keeps remote-shutoff capability. Pick the option that matches the as-built reality.

After Step 2, Reonic completes the remaining review; this does not require any action from you. Your role for that filing is done unless the VNB raises a late inquiry.

Step 2 is the Fertigmeldung (PV completion notice): submitting it is the completion signal, and the base fee covers the whole lifecycle, so Step 2 carries no separate charge. Once Step 2 is accepted, the asset is considered completed for VNB purposes.

Respond to a VNB inquiry (Rückfrage)

When the VNB sends an inquiry, an in-app banner appears reading "Neue Rückfrage".

1. Open the filing's detail view.
2. Read the VNB's message in the chat panel on the filing.
3. Click Reply / Add message. Choose a chat-only reply (explanatory text, no new attachments) when the VNB needs a written answer, or reply with files to upload supporting documents (revised wiring diagrams, additional meter photos, customer-signed amendments, EVU-specific forms) into the additional-file slots 1 through 8. Each slot accepts one document.
4. Click Send. Your response is sent to the VNB.
5. Wait for the VNB's next response: Accepted, another inquiry (respond again), or rejected (the filing archives).

Correction rounds are unlimited. Some filings clear in one round, others take five or more, and there is no additional charge: the base fee covers the whole inquiry lifecycle.

Documents the VNB sends back are filed for you automatically. Incoming VNB forms and returned documents land in a dedicated Netzanmeldung Unterlagen folder on the project, created the first time an incoming document arrives, instead of sitting loose in the file list. Look there for whatever the VNB attached. Incoming files may be images, PDFs, or ZIP archives.

Pro tip: The in-app banner is the primary signal that a Rückfrage has landed. If you miss it, the filing status is the next-best signal. The chat panel preserves the entire conversation, so you can read back through earlier rounds if a new inquiry references something said two weeks ago. The same Brauchst du Hilfe? button in the form header reaches a Reonic Service contact when an inquiry needs Reonic-side help.

VNB-specific procedures

Different German Verteilnetzbetreiber have slightly different submission requirements, paper forms, and processing speeds. You do not pick the VNB manually: Reonic routes each filing to the right VNB from the address and meter data on the filing, so everything flows through Reonic and you do not need any grid-operator login of your own. This covers Stromnetz Berlin, Westnetz, Bayernwerk, Avacon, Mitnetz Strom, and the long tail of regional and municipal Stadtwerke networks.

VNB-specific quirks worth knowing:

• Processing speed varies widely. Some VNBs respond within days; others take 6–8 weeks for a Rückfrage. The pace is whatever the VNB does.
• Some VNBs require additional EVU-specific forms. Supplementary cover letters or local-jurisdiction declarations. When this is the case, the inquiry comes back asking for the specific form; you upload it through the additional-file slots.
• Bundesländer rules differ for storage thresholds. What is a "simple" PV-plus-battery in one state may be a "complex" filing in another. The Step-1 photo and document set adapts to the planned-system specs; you do not pick the right variant manually.

Single-line schematic (einpoliges Schema)

A einpoliges Schema (single-line electrical schematic) shows the customer's electrical installation in simplified form: main service, sub-distributions, and the PV, heat-pump, or wallbox connection points. Some VNBs request it during the Grid Registration filing.

You can request a single-line schematic from Reonic once the asset planning is complete and the installation phase has captured the electrical topology. The request lives in the project's planning / installation phase, not in the Grid Registration tab directly: once the planning step is finalised, Reonic generates the schematic on demand.

If the VNB explicitly asks for the schematic during an inquiry round, mention it in the chat reply and upload the generated schematic into one of the additional-file slots.

Bill of materials (Stückliste) for the filing

The Step-1 form pulls the Stückliste (bill of materials) for the asset from the planning step automatically, so the form references your planning output rather than asking you to re-enter the components yourself. The BOM the VNB needs:

• Module manufacturer, model, count, total kWp.
• Inverter manufacturer, model, output rating.
• Battery storage (if any): manufacturer, model, capacity.
• Wallbox (if any): manufacturer, model, rated charging power.
• Mounting system manufacturer and type.

If a component is missing from the planning step, go to Plan > Components and add it before opening Step 1.

Battery / storage upgrades to an existing PV system

Adding battery storage to a PV system that is already grid-connected requires a Erweiterungsanmeldung (extension registration), because the VNB regulates the entire generation-and-storage system together. File it through the same Grid Registration tab: open the project, file a fresh German PV filing, and indicate in the customer-data section that this is an extension. The Vollmacht and the original Einspeisezusage and customer documents are required again.

The fee matches a fresh PV filing unless your contract includes an extension discount, so check with your account manager.

Submission timeline and typical processing time

Timing depends on the VNB, the filing's complexity, and whether the VNB opens inquiry rounds. Rough expectations:

• Reonic submits to VNB — Shortly after you click Submit
• VNB initial response (accept / inquire / reject) — 1–6 weeks, average ~2–3 weeks
• Per-inquiry round (you respond, VNB responds) — 1–4 weeks per round
• **Einspeisezusage issued after acceptance** — Days to weeks after acceptance
• Meter swap (two-way / smart) executed by VNB — 4–12 weeks after Einspeisezusage
• Step 2 commissioning submission — Same-day when you submit

A clean German PV filing typically settles in 6–12 weeks; an inquiry-heavy filing can run 3–6 months.

Note: The VNB requires Step 2 within 6 months of the physical install. Track that deadline yourself. If you miss it, the filing may have to be redone with penalty paperwork.

Status tracking in the Portal

Inside the Grid Registration tab, the status indicator at the top of the filing shows where it sits in the process. The stages most relevant to you as the installer:

• Draft. You have created a draft, not yet submitted.
• Submitted. Step 1 has been submitted to the VNB.
• *Inquiry (Rückfrage).* The VNB is asking for more info. The "Neue Rückfrage" banner appears.
• VNB accepted. The VNB has accepted Step 1.
• Einspeisezusage erhalten. You have submitted Step 2; the customer has feed-in permission.
• Rejected. The filing has been rejected and archived.
• Closed. Review is complete and the filing is closed.

After Step 2, the filing moves through Reonic's final review without any action from you.

The chat history in the filing's detail view preserves every VNB message and every reply you sent, in chronological order. The activity feed on the project records each status change and document upload, giving you an audit trail across the project's whole journey.

Archived filings

When a filing is archived (after a rejection, or when it is closed out), it becomes read-only and shows a warning banner: "Dieses Netzanmeldung ist archiviert. Sie wird nicht weiter bearbeitet." ("This grid registration is archived. It will not be processed further.") Inquiries and file uploads close on an archived filing.

Archived records move to a dedicated archive list view rather than cluttering the active queue, so your in-flight filings stay clean. To continue work on an asset whose filing was archived, start a fresh registration.

Reonic's role vs. installer's role vs. VNB's role

• **Installer (you)** — Capture the customer Vollmacht. Take meter and installation photos. Submit Step 1 with the planning file. Respond to VNB inquiry rounds with chat replies plus additional files. Submit Step 2 after the physical install.
• **Reonic** — Handle the VNB submission and correspondence. Move the filing through its lifecycle. Invoice you weekly.
• **VNB (grid operator)* — Review Step 1 paperwork. Issue inquiries or accept. Coordinate the meter swap. Issue the Einspeisezusage*. Process Step 2.
• **End customer** — Sign the Vollmacht. Optionally sign any extra customer-side declarations the VNB requests during inquiry rounds. The customer pays the installer; the installer pays Reonic.

Pro tip: Reonic does the back-office work, but the legal filing is in the installer's name (with customer authorisation). If a VNB rejects, the rejection lands on the installer's account, not Reonic's. Keep your Vollmachts clean and your filings accurate.

Weekly billing

Grid Registration is invoiced weekly in all three countries. Each week, your submitted-and-unbilled filings are gathered, your free quota is applied, and the rest are invoiced.

Germany:

• Free quota applied first. The first PV filings each period are billing-free; the same applies to heat-pump filings.
• Invoice built. For the remaining paid filings, an invoice is issued with 19% German VAT and 7-day payment terms, with a separate line item per filing variant (PV, heat pump, plus any wallbox or MaStR add-on).

Italy: a flat per-filing line (Pratica GSE), with your free quota applied first.

Brazil: a flat per-filing line (Brazilian reais), with your free quota applied first.

The invoice arrives at the billing contact configured for your workspace. A filing submitted this week is invoiced the following week, so plan for a delay between work performed and invoice arrival.

Pro tip: Add-ons are billed even on free items. A free Germany PV filing with the wallbox add-on still generates a wallbox line. Free quotas cover the base PV or heat-pump fee only and do not roll over to add-ons.

Note: Rejected filings still bill in Germany, because the VNB work was still performed. This is contract-dependent, so confirm with your account manager if it matters for your invoicing.

Common rejections and fixes

Recurring reasons the VNB rejects or sends a Rückfrage:

• Missing or stale Vollmacht. The Vollmacht must be signed within a reasonable window (some VNBs accept up to a year old, others demand recent). Re-sign with the customer and re-upload.
• Meter photo unreadable. Re-take in good light, framing the meter number clearly.
• Project planning file references the wrong address. The address on the planning file must match the meter location and the customer-data address. Re-export the planning file with the correct address and re-upload.
• Storage or wallbox not declared. If the install includes battery or wallbox and the BOM does not show it, the VNB inquires. Update the planning step's components and re-submit.
• Customer name mismatch. The customer's name on the Vollmacht, on the customer data, and on the meter contract must all match. Fix the customer record in CRM and re-upload the Vollmacht.
• Existing-meter conflict. A registration request already exists for the same meter under a different email address: see Meter requirements above.
• Voltage class wrong (rare). Some VNBs require the customer-side voltage class to match the inverter spec. Update the technical-specs section.
• Single-line schematic missing. Some VNBs request it explicitly during inquiry. Generate it from the planning step and upload via additional files.

If the rejection reason is genuinely VNB-side (an outage, an internal VNB process error, missing VNB-side data), respond in chat with a note and re-attempt. If it persists, escalate to your Reonic account manager: Reonic can escalate stuck filings with direct VNB contacts.

After Einspeisezusage — next steps

Once the filing reaches Einspeisezusage erhalten, Reonic completes the remaining review. From the installer side:

• The VNB schedules a meter swap, typically 4–12 weeks later. The customer needs to be home or accessible for the meter installation visit.
• The customer's PV system is legally cleared to feed into the grid. The Einspeisezusage is the legal go-ahead: the customer's energy production now counts and the feed-in tariff applies.
• Marktstammdatenregister entry. If you ticked the MSD add-on, Reonic handles the MaStR entry on your behalf. If you did not, you (or the customer) file the MaStR entry within 30 days of commissioning, which the federal regulator enforces separately from the VNB.
• Final invoicing. The weekly billing picks up the filing for invoicing if it has not been billed yet.
• Closed. Once review is complete, the filing is closed and archived, and the project moves on to its operating phase.

Italy — single-step paid filing

Italy is a single-step submit-and-done surface, with no Step-1/Step-2 split and no in-system chat. It is billed at a flat per-filing fee.

1. Open the project Grid Registration tab. The Italy form loads with no Step-1/Step-2 split.
2. Fill customer data plus the 3 mandatory documents (a recent utility bill, the customer power-of-attorney, and a customer ID document).
3. Optionally toggle ENEA enrolment (Pratica ENEA). Whether it adds to your fee depends on your billing setup; your Reonic account manager can confirm.
4. Optionally upload a File aggiuntivo: a single supplementary-document slot for anything beyond the standard slots.
5. Click Submit.

From there the filing is in Reonic's hands: Reonic handles the Italian VNB correspondence, and the fee is invoiced with the weekly billing (with your free quota applied first). For status updates, contact your Reonic account manager.

Pro tip: The Italy form header has a Hai bisogno di aiuto? (Need help?) button that opens a Reonic Service contact for Italy. Use it for questions about the Italy filing or the ENEA add-on.

The Italy Grid Registration covers the basic VNB filing. The GSE (Gestore dei Servizi Energetici, Italy's renewable-energy support agency) enrolment for feed-in tariffs / Scambio sul Posto, and monthly energy-distribution data (which lives on the GSE side), are filed and retrieved through GSE's own channels.

Brazil — paid filing with a staged workflow

Brazil moves through a richer staged workflow than Italy, and is billed at a flat per-filing fee.

1. Open the project Grid Registration tab. The Brazil form loads.
2. Pick the client type: PJ (Pessoa Jurídica, a business entity, CNPJ required) or PF (Pessoa Física, an individual, CPF required).
3. Fill installer data, client data, technical specs (voltage class, circuit-breaker type), and beneficiary UC numbers (utility customer IDs).
4. Upload the power-of-attorney, installation photos, and datasheets.
5. Click Submit. The filing enters the Brazil workflow at the first stage, Novo Projeto.

From there:

• Reonic handles the Brazilian VNB correspondence.
• The filing progresses through the workflow stages, from Novo Projeto to Concluído. You get an email notification on each forward move.
• You see the status progression read-only and can chat with Reonic via the chat overlay on the filing.

The fee is invoiced with the weekly billing, with your free quota applied first.

Things to know

• The lifecycle is country-specific. Two steps in Germany (Step 1 plus Step 2), single-step in Italy, and a staged workflow in Brazil.
• The Vollmacht is mandatory for Germany. Without it you cannot submit Step 1.
• Free quotas do not pool. The PV free quota and the heat-pump free quota are separate counters; one does not bleed into the other.
• Filings that were submitted and later archived still bill (unless billing-free via quota), because the work was performed.
• Rejected filings still bill. The work was still done; the rejection is a VNB decision.
• Chat with the VNB goes through Reonic, not direct. You do not get the VNB's email; everything routes through Reonic.
• *You are the Deklarant (declarant) on a filing, acting under the customer's Vollmacht. Pick Unternehmen (company) when the declarant is your installer business, or Einzelperson* (individual) only if you are a sole proprietor filing in your own name.
• The customer's last touchpoint is the Vollmacht. They sign it on paper or PDF and receive whatever email notifications your workspace has configured, typically "Grid registration submitted" and "Einspeisezusage received." Anything beyond that, you communicate directly.
• Adding a wallbox after the PV filing is in flight? File a correction round if the VNB has not yet processed Step 1, or add a separate filing once Step 1 is closed.
• To redo a filing after it is archived, create a new one.
• Electrician certificate numbers. When a manufacturer requires a registered-electrician certificate number (for example Sigenergy components), enter the certificate number in the technical-specs section of Step 1. It is captured as a free-text field.
• KfW subsidies file through the Subsidy Service. Grid Registration handles the VNB filing; the KfW and federal subsidy applications run through the separate Subsidy Service. Open the project Installation > Subsidy tab. See Subsidy in this Deep Dive section.
• Re-take photos for grid registration. Capture the photos the filing needs directly, even if roof imagery was already shot for planning; the filing needs its own photo set.
• Marktstammdatenregister (MSD) is an add-on, not a standalone. You cannot file MSD-only without a Grid Registration; it is included inside a PV or heat-pump filing.

Who supports me on grid registration and financing?

Two distinct support paths:

• Grid Registration questions go to your Reonic account manager or the Reonic support team.
• KfW and financing questions go to the Subsidy Service (separate from Grid Registration). Reonic handles BzA, KfW filings, and the associated documentation. See Subsidy in this Deep Dive section. For customer financing, the financing-specific support is via your finance-partner contact: Reonic's role on financing is the data handoff at signature, not the lender relationship.

Need help?

• Step-by-step questions about this flow → contact your Reonic account manager.
• VNB rejections that do not make sense → message your account manager; Reonic can escalate to direct VNB contacts.
• Feature requests or something missing → contact Reonic support.
• Bug reports → contact Reonic support with the project reference and where in the Portal it happened.
