Home battery · storing power
Use daytime solar power in the evening.
A home battery stores the surplus from your solar panels, so you use it yourself in the evening instead of selling it cheaply to the grid.
In short
We work with five systems. Huawei and Tesla are the established names, Sigenergy and Fox ESS the fastest-growing brands in Europe, and BYD works with many inverters, which is handy if you already have solar panels. Every system uses LFP cells, the safest and most durable cell chemistry for the home.

What we look at
Well chosen, lasting enjoyment.
More self-consumption
Without a battery, you often use only a third of your own solar power. With a battery, you use a much larger share yourself.
Peak shaving
The battery absorbs peaks when the oven, heat pump and EV charger are running at the same time. In Flanders, that can lower your capacity tariff.
Grows with you
You can expand the modular systems later with extra modules, for example when you add an electric car or a heat pump.
Frequently asked questions
Good to know.
A battery mainly pays off if you have a lot of solar power left over during the day and use a lot in the evening. We look at your consumption and your solar panels and tell you honestly whether a battery makes sense for you.
That depends on how much you use in the evening and at night, and how much surplus your panels produce during the day. A battery that is too big never fills up, one that is too small soon runs empty. We calculate it from your consumption data.
Lithium iron phosphate: a cell chemistry that is more stable and handles more charge cycles than older lithium batteries. Every system in our range uses LFP.
Only if the system has a backup power function and is connected that way. Not every set-up does this as standard. Let us know if you want it and we'll take it into account.
With the modular systems, yes: the Huawei LUNA2000 in modules of 6.9 kWh, Fox ESS and BYD per module, and Sigenergy up to 48 kWh. The Tesla Powerwall 3 has a single fixed capacity.
