As an EU member state, the country applies CE marking and the EU Battery Regulation (EU) 2023\/1542 directly, and its grid connections follow the European Requirements for Generators, RfG (EU) 2016\/631.

How Belgium Structures Its Grid Connection Framework<\/strong><\/strong><\/h3>\n\n\n\n<p>Belgium operates a two-layer grid connection framework.<\/p>\n\n\n\n<p><strong>At the transmission level (federal):<\/strong> The Federal Technical Grid Code \u2014 which the Belgian legislator established by Royal Decree of 22 April 2019 and published in the Belgian Official Gazette on 29 April 2019 \u2014 governs connections to the high-voltage network that Elia operates. Under the RfG framework, storage modules fall into power-generating module Types A\u2013D.<\/p>\n\n\n\n<p><strong>At the distribution level (regional):<\/strong> The technical prescription C10\/11, which Synergrid (the federation of Belgian grid operators) issues, governs distribution-level connections.

Every grid-connected generation or storage unit \u2014 PV inverters, battery inverters, hybrid inverters, bidirectional EV chargers \u2014 must pass Synergrid homologation before installation and commissioning, and must appear on the official list.<\/p>\n\n\n\n<p>Here are the key facts about C10\/26:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Listed by firmware version<\/strong> \u2014 a firmware update can trigger re-homologation<\/li>\n\n\n\n<li><strong>Free of charge<\/strong> \u2014 Synergrid does not charge for homologation<\/li>\n\n\n\n<li><strong>Includes requirements for automatic disconnection \/ anti-islanding protection<\/strong> (C10\/11 \u00a77.5)<\/li>\n\n\n\n<li><strong>Prefers EN 50549-1 \/ -2 \/ -10 test reports<\/strong> as test evidence<\/li>\n\n\n\n<li><strong>Requires laboratory testing of the grid disconnection relay (NOR) for units above 30 kVA<\/strong><\/li>\n\n\n\n<li><strong>Since 17 April 2025, even plug-and-play batteries need a dedicated C10\/26 plug-and-play listing<\/strong><\/li>\n<\/ul>\n\n\n\n<p>What happens without it? You may still import and sell the equipment, but you cannot legally connect it to the Belgian grid \u2014 which reduces its commercial value to effectively zero. Inspection bodies and DSOs verify the list at registration, and tenders use it as a first screening criterion, checking by brand, product reference number, and firmware version.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. <a href=\"http:\/\/economie.fgov.be\/fr\/themes\/energie\/...\/securite-et-controle-des-installations-electriques\">AREI\/RGIE: The Mandatory Electrical Inspection Before Commissioning<\/a><\/strong><\/h3>\n\n\n\n<p>Beyond homologation, every installation must clear an electrical inspection. The AREI\/RGIE (General Regulations on Electrical Installations), which the Belgian legislator established by Royal Decree of 8 September 2019 and which has applied since 1 June 2020, creates a mandatory inspection regime that accredited inspection bodies such as Vin\u00e7otte, BTV, OCB, and ACEG carry out:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>New installations and modifications \u2014 including adding a battery to an existing system \u2014 must pass inspection before commissioning<\/li>\n\n\n\n<li>The inspection body (not the installer) issues the certificate of conformity, which remains valid for 25 years<\/li>\n\n\n\n<li>Without this certificate, the DSO will refuse commissioning registration<\/li>\n\n\n\n<li>A Royal Decree of 6 October 2025 overhauls the DC-side provisions for PV and batteries, applicable from 1 April 2026<\/li>\n<\/ul>\n\n\n\n<p>What happens without it? Illegal operation, administrative fines (in Flemish practice reaching the order of \u20ac1,500), mandatory remediation, and paid re-inspection if the first inspection fails.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5. DSO Registration: <a href=\"http:\/\/mijn.fluvius.be\">Fluvius<\/a>, ORES, RESA, and Sibelga<\/strong><\/h3>\n\n\n\n<p>In addition to certification and inspection, grid operator registration is a separate, mandatory step:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Flanders \u2014 Fluvius:<\/strong> storage registration has been mandatory since 1 January 2017 via Mijn Fluvius; it is free online for units below 25 kVA.

What Certification Means in Practice<\/strong><\/h3>\n\n\n\n<p>Understanding the rules is one thing; seeing how they play out commercially is another. In practice, certification touches every stage of the product lifecycle:<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>8.1 Market access (import, sales, customs)<\/strong><\/h5>\n\n\n\n<p>Without CE marking or EU Battery Regulation compliance, you cannot legally sell the product. Without C10\/26 listing, you cannot legally connect it to the grid \u2014 the hardest access point compared with neighbouring countries, and one that now extends even to plug-in batteries.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>8.2 Installation and grid connection<\/strong><strong><\/strong><\/h5>\n\n\n\n<p>Without the AREI inspection certificate, the DSO refuses commissioning registration. Moreover, failed inspections require paid re-inspection and remediation.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>8.3 Procurement and tenders<\/strong><strong><\/strong><\/h5>\n\n\n\n<p>Tenders and distribution channels treat the C10\/26 list as the first screening criterion, verified by firmware version. Buyers should therefore check the Synergrid website by brand and product reference number before placing an order \u2014 not on the list means disqualified.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>8.4 Subsidies<\/strong><strong><\/strong><\/h5>\n\n\n\n<p>The Flemish home battery subsidy ended on 31 March 2023. The remaining regional support measures (Brussels\/Wallonia schemes, tax rebates) all rely on the AREI certificate and DSO registration as proof \u2014 no proof, no claim.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>8.5 Insurance and financing<\/strong><strong><\/strong><\/h5>\n\n\n\n<p>Fire insurers commonly require the AREI inspection certificate and proof of compliant installation; likewise, financing due diligence requires C10\/26 homologation and grid registration. Without them, insurers may reject claims and financing can fall through.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>9. Five Practical Recommendations for Suppliers and Buyers<\/strong><strong><\/strong><\/h3>\n\n\n\n<p>Based on everything above, here are five concrete actions you can take:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Treat C10\/26 homologation as priority #1 for Belgium.<\/strong> Submit the technical file (EN 50549 test reports, datasheets) to Synergrid early. Remember that Synergrid manages the list by firmware version \u2014 firmware updates must be re-homologated, and plug-and-play versus fixed-installation variants need separate product reference numbers.<\/li>\n\n\n\n<li><strong>Ensure battery-capable inverters carry dual approval.<\/strong> Hybrid inverters must hold the additional &#8220;storage&#8221; use-case approval, not just PV approval.<\/li>\n\n\n\n<li><strong>Ship an AREI-ready documentation package with every unit:<\/strong> a single-line diagram template, the EU Declaration of Conformity, an installation manual (in Dutch and French), and automatic disconnection (\u00a77.5) documentation.<\/li>\n\n\n\n<li><strong>Remind buyers of their registration duties.<\/strong> In the Fluvius area, plug-in devices totalling 800 W or more must be registered within 30 days; fixed installations register free of charge, and registration is the precondition for feed-in compensation.<\/li>\n\n\n\n<li><strong>Track the regulatory calendar.<\/strong> C10\/11 ed.2.4 is the current edition, and the AREI DC-side overhaul applies from 1 April 2026 \u2014 update your Belgium-specific settings and documentation accordingly.<\/li>\n<\/ol>\n\n\n\n<p><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>10. FAQ: Battery Certification in Belgium<\/strong><strong><\/strong><\/h3>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>Is CE marking enough to sell a <a href=\"https:\/\/www.lvfuenergy.com\/pl\/kategoria-produktu\/48v-lifepo4-battery\/\">home battery<\/a> in Belgium?<\/strong><\/h5>\n\n\n\n<p>No. CE marking and the EU Battery Regulation (EU) 2023\/1542 allow you to place the product on the market, but grid connection additionally requires Synergrid C10\/26 homologation, an AREI\/RGIE inspection, and DSO registration.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>What is the C10\/26 list?<\/strong><\/h5>\n\n\n\n<p>It is Synergrid&#8217;s official homologation list of grid-connected generation and storage units approved for the Belgian distribution grid, maintained per product reference and firmware version under the C10\/11 technical prescription.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>Do plug-and-play (plug-in) batteries need certification in Belgium?<\/strong><\/h5>\n\n\n\n<p>Yes. Since 17 April 2025 (C10\/11 amendment ed.2.2), plug-and-play devices such as balcony PV, small mobile batteries, and bidirectional EV chargers may connect to the grid \u2014 but only with a C10\/26 plug-and-play listing. In the Fluvius area, plug-in devices totalling 800 W or more must also be registered within 30 days.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>Do I need a new inspection when adding a battery to an existing solar installation?<\/strong><\/h5>\n\n\n\n<p>Yes. Under AREI\/RGIE, adding a battery counts as a modification and requires re-inspection by an accredited body before commissioning.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>What test reports do I need for C10\/26 homologation?<\/strong><\/h5>\n\n\n\n<p>EN 50549-1, -2, and -10 test reports are the preferred evidence. Units above 30 kVA additionally need laboratory testing of the grid disconnection relay (NOR).<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>Is the Flemish home battery subsidy still available?<\/strong><\/h5>\n\n\n\n<p>No. It ended on 31 March 2023. Current support consists mainly of regional measures and tax rebates, which change frequently and require AREI and DSO registration documents.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>11.
