Overview

AI-generated overview

Free PlanElec endpoint for Belgian AREI/RGIE electrical planning: cable sizing, Synergrid C10/26 inverter checks, LED strip calculations and regulation lookup.

What you can do
  • Check inverters against the Synergrid C10/26 homologation list, with typeahead brand/model lookup and manufacturer datasheet data
  • Size copper or aluminium cable cross-sections for residential circuits under AREI/RGIE, with voltage drop and breaker checks
  • Calculate LED strip power, current, feed points, power supply and feed cable
  • Search PlanElec help guides and return titles, summaries and links
  • Search Book 1 of the Belgian AREI/RGIE and read individual articles by number
When to use it
Useful when planning or checking residential electrical installations in Belgium: verifying whether an inverter may be connected to the grid, choosing cable cross-sections, sizing LED strip supplies, or looking up AREI/RGIE articles and PlanElec guides.
Requirements
Remote streamable HTTP endpoint at planelec.be; no account, API key, environment variables or headers declared. Network access required.
Before you install
Results are planning aids, not an official inspection (keuring). The endpoint is public and read-only for calculators, help and regulations; saved projects and planning changes require a paid PlanElec Pro subscription. Cite the source when passing results on.

Installation

In SourceWeft

  1. Open PlanElec Calculators in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/be.planelec%2Fcalculators/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

check_inverter_c10_26

Check an inverter against Synergrid C10/26

Checks whether a PV inverter, battery inverter or other power-generating unit (PGU) is on the Synergrid C10/26 list of devices homologated for connection to the Belgian grid. Returns the outcome (found, found_with_limitations, expired, not_found, brand), matching devices with homologation dates, limitations and firmware versions, and homologated alternatives when nothing matches. Where available, each match also carries a separate "datasheet" object with manufacturer datasheet values (DC voltage, MPPT data, links, source URLs, status, last verified date); these are NOT checked by Synergrid and are not part of the approval. Search by brand and model, for example "Huawei SUN2000-10KTL".

suggest_inverter_c10_26

Suggest brands or models from the Synergrid C10/26 list

Typeahead for the Synergrid C10/26 list: given a partial brand or model name, returns matching brands with device counts or, once a brand is recognised, its homologated models. Use this to resolve an ambiguous device name before calling check_inverter_c10_26.

Parametersqueryrequiredlocale

get_inverter_datasheet

Get inverter datasheet data

Returns manufacturer datasheet data for an inverter from the Synergrid C10/26 list: maximum DC voltage, MPPT count and range, current limits per MPPT, start voltage, maximum PV power, battery capability, optimizer architecture, links to the datasheet and installation manual, the product photo URL, source URL and page per value, status (verified = stated in the datasheet, secondary = unconfirmed) and the date last verified. These are manufacturer statements and are NOT part of the Synergrid approval; use check_inverter_c10_26 for the approval status. Look up by Synergrid reference (GLV…) or by brand and model.

Parametersbrandmodellocalereference

size_cable_arei

Size a cable per AREI/RGIE

Calculates the required copper or aluminium cable cross-section for a residential circuit under the Belgian AREI/RGIE: design current, voltage drop per cross-section, protection check against the breaker rating and the recommended cross-section. Provide the load (A, W, kW or kVA), one-way cable length in metres, the network (1x230V, 3x230V, 3x400V) and the breaker rating; other fields use the defaults for a typical socket circuit. The response includes a shareable link that opens the same calculation on planelec.be.

calculate_led_strip

Calculate an LED strip: current, power supply, feed points

Calculates power, current (total and per channel), required feed points, power-supply size and the extra-low-voltage feed cable for an analogue LED strip (5/12/24/48 V DC; single colour, CCT, RGB, RGBW, RGB+CCT). Provide the strip length in metres and either a preset or the datasheet values (voltage, colour channels, watts per metre at full load). Optional: cut unit, maximum length per feed, number of feeds, power-supply reserve, feed-cable length, material and cross-section, and voltage-drop limit. Planning values from datasheet data, not a manufacturer guarantee; current-carrying capacity, heat and AREI/RGIE rules for SELV, bathrooms and outdoor areas are not checked. The response includes a shareable link that opens the calculation on planelec.be.

search_help_guides

Search the PlanElec help center

Searches the PlanElec guides about getting started, automatic planning, document exports, AREI self-check coverage, floor plan import, symbols and circuits in the visitor’s current language. Returns up to five guides with title, summary, category and a link to the full article; the article text itself is not returned.

Parametersquerylocale

search_regelwerk

Search the Belgian AREI/RGIE regulations

Searches Book 1 of the Belgian AREI/RGIE (Royal Decree on electrical installations) in the language of the text: Dutch, French or German; English uses the German text. Returns up to ten articles with number, title, an excerpt, the edition in force today and a link to the article in the PlanElec reader; the full article text is not returned, use get_regelwerk_article for it. Search by keywords or by article number such as 4.2.4.3. Results are planning aids, not an official inspection.

Parameterslimitqueryrequiredlocaleversion

get_regelwerk_article

Read an AREI/RGIE article

Returns the text of one article of Book 1 of the Belgian AREI/RGIE by its number (for example 4.2.4.3 or "AREI 7.1.4.3"), in the language of the text (Dutch, French or German; English uses the German text), with the edition, change notices of amending decrees, the titles of its sub-articles and a link to the article in the PlanElec reader. Cite the article number and edition when you pass the content on. Use search_regelwerk to find the number.
