Solar power and a home battery: what do they ask of your connection?
Solar panels feed back into a grid that's full in many places. A good connection and meter cupboard keep your installation running reliably — and make you ready for a home battery.
Three reasons why 3-phase matters here
Not every solar installation needs 3-phase power — but in these cases it does.
The home battery is coming — with subsidy
Now that the net-metering scheme has been phased out, storing your own solar power is becoming ever more attractive. The home battery is on the rise, and the government is helping: in 2026 an ISDE subsidy of € 85 per kWh of storage capacity applies, up to a maximum of about € 1,020 per home.
Do note: as with the heat pump, the subsidy applies to the battery itself — not to changes to the fuse box or upgrading the connection. We include those costs honestly in the price estimate.
Grid congestion: why preparing pays off
The power grid is reaching its limits in large parts of the Netherlands. For households that means longer waiting times for upgrades and stricter rules around feed-in. Have your meter cupboard properly prepared now — with a 3-phase fuse box and, where needed, an upgraded connection — and you'll benefit for years, even if the home battery or EV charger comes later.
