Two reasons to get a home battery now
Pick the profile that best matches you, and you'll know right away whether this battery is a fit.
You have solar panels but inefficient storage or none at all
You have solar panels and feed power back during the day for less and less. From 1 January 2027 net metering ends entirely, and storing becomes the norm.
- Covers the evening and night of an average household
- Charges automatically during the day with your solar surplus
You pay premium rates during peak hours
You have a dynamic contract or high evening peaks. The battery charges during cheap hours and discharges exactly when power is expensive.
- Works with dynamic suppliers such as Zonneplan, Tibber and ANWB Energie
- Automatically responds to hourly prices and peak periods
- Also worthwhile without solar panels

Questions about this product
Deye. That comes from our dataset of 544 combinations that manufacturers released in their own compatibility documents, not from a claim of ours. If your inverter is not listed, that only means the manufacturer makes no statement about it, not that it will not work. The manufacturers attach conditions, most often communication settings and the inverter's lithium mode.
LFP (lithium iron phosphate). We did not take that from the supplier but looked it up per model, in this case in the manufacturer's datasheet. All 333 batteries we sell were checked this way and all 333 are LFP; 15 models were rejected by the same check and withdrawn from sale. LFP is the only chemistry we stock, because it is thermally more stable than the NMC chemistry found in many older home batteries.
Yes. This is a fixed home battery wired into the consumer unit, which in the Netherlands is work for a certified installer. We sell the hardware; on this page you can request a no-obligation installation quote from our installation partner, who emails a fixed total price. You are not obliged to accept it and can have the battery fitted by your own installer.
