With the phase-out of the net-metering scheme in 2027, a home battery is becoming increasingly important for homeowners with solar panels. From 2027 you can no longer feed solar energy back to the grid at the full tariff.
A home battery stores your solar energy for use in the evening and at night. This raises your self-consumption from an average of 30% to 60-80%, which translates directly into lower energy bills.
Higher self-consumption: use 60-80% of your own generated energy instead of 30-40%.
Protection against rising energy prices: less dependence on the grid and fluctuating tariffs.
Smart energy management: with a dynamic energy contract your battery charges when electricity is cheap and uses stored energy when the price is high.
Backup power: in case of a power outage you can fall back on your battery.
Payback time 5-8 years: thanks to self-consumption and dynamic tariffs a home battery now pays for itself faster than ever.
The Enphase IQ Battery is an AC-coupled storage system with integrated micro-inverters. Enphase is already the market leader in micro-inverters more than 30% of solar panel owners in the Netherlands use Enphase.

3-phase compatible: Inverters from 5 kW to 30 kW, suitable for smaller and larger installations.
Price: From €6,000 – €7,500 for a 5-8 kWh configuration including installation.
An Enphase IQ Battery 5P (5 kWh) costs between €5,000 and €7,500 including installation. A Sigenergy SigenStor starts at €6,000 for a 5-8 kWh configuration.
Modern home batteries with LFP cells last at least 6,000 charge cycles (15-20 years). Enphase offers a 15-year warranty, Sigenergy 10 years.
A home battery works best with solar panels, but it is also profitable with a dynamic energy contract.
Yes, both Enphase and Sigenergy offer backup power functionality (UPS/EPS).
