Why 800 W?
800 W of inverter output is the limit most European countries set for solar kits you install yourself, and the European Commission recommended it to all member states in April 2026. An 800 W kit covers the electricity your home uses constantly during the day: fridge, router, standby devices and whatever runs while the sun shines.
Panels and output
The 800 W limit applies to the microinverter, not the panels. Our kits pair two panels of 450 to 485 Wp with an 800 W microinverter, so the kit reaches full output for more hours of the day. A two-panel kit produces up to 1,600 kWh a year in southern Europe, less further north. The savings calculator estimates it for your home.
Performance or Eco?
Performance kits use Aiko panels with ABC cells, among the most efficient on the market, and the Marstek M2-800 microinverter, which connects to Marstek batteries and the Smart Meter. Eco kits use Tier 1 panels at a lower price. Both come in versions for balcony, wall, flat roof or garden, tile roof and metal roof.
Rules in your country
Whether you need to register an 800 W kit, and how many panels you may connect, depends on the country. See our plug-in solar rules by country.
