- SolarEdge blocks automated downloads, so our archived datasheet is the October 2022 edition. We checked the key figures against the July 2024 edition on SolarEdge's site.
- Only works with SolarEdge inverters. It can't be added to another brand's solar inverter.
- Using a wired RS485 link instead of SolarEdge Home Network can reduce usable energy to 9.5 kWh, according to the datasheet.

Questions people ask
How much usable capacity does the SolarEdge Home Battery 400V have?
9.7 kWh (Per battery, 100% depth of discharge).
Can the SolarEdge Home Battery 400V be expanded?
Up to 3 batteries per inverter. Maximum usable storage: 29.1 kWh (calculated).
How long will the SolarEdge Home Battery 400V run a house in a power cut?
Running essentials only (fridge-freezer, lights, Wi-Fi, TV and device charging, about 156 W on average), a full Home Hub SE3680H + 1 battery (9.7 kWh) lasts roughly 2 days 11 hours. Heavy loads such as a heat pump, electric shower or EV charger cut this sharply. Use the calculator on this page with your own appliances.
What warranty does the SolarEdge Home Battery 400V have in the UK?
10 years, guaranteeing 70% of capacity or 26 MWh of throughput, whichever comes first.
What does the SolarEdge Home Battery 400V need to provide backup power?
SolarEdge Backup Interface (bought separately) with the Home Hub inverter.
