SolarEdge Home Battery (48V LFP)
SolarEdge is one of the two dominant rooftop solar inverter brands in the UK alongside Enphase. Their home battery is designed exclusively for SolarEdge systems — it won't work with anything else, which is both its strength (deep integration) and its weakness (complete ecosystem lock-in). At 9.7kWh and up to three units in parallel, it covers most UK home storage needs.
Pros
- 9.7kWh LFP — substantial capacity for a typical UK household
- Deep integration with SolarEdge inverter ecosystem — no configuration complexity
- mySolarEdge app gives unified monitoring across panels and battery
- Stackable to 3 units for 29.1kWh total capacity
- 10-year warranty as standard
- Compatible with SolarEdge EV charger for solar-to-EV optimisation
Cons
- Only works with SolarEdge inverters — zero compatibility with other systems
- Requires MCS-certified installer for UK installation
- £3,000–£4,000 per unit before installation — expensive per kWh versus DIY alternatives
- No third-party integration — Home Assistant access is limited
- SolarEdge's UK installer network is extensive but pricing varies significantly
The SolarEdge Home Battery review is short. Do you have SolarEdge panels on your roof? Buy this. Do you not? This product is entirely irrelevant to you. Come back when we review something you can actually buy.
That's slightly reductive but only slightly. The SolarEdge Home Battery is a proprietary product in a proprietary ecosystem. SolarEdge's inverter technology uses a power optimiser architecture that requires SolarEdge-compatible storage — their battery is the only option that integrates cleanly.
For SolarEdge owners
If you have an existing SolarEdge rooftop system and want to add storage, the Home Battery is the path of least resistance. The integration is seamless — the mySolarEdge app manages both the panels and the battery in a unified interface, optimisation is automatic, and the installer process is straightforward for any SolarEdge-certified company.
The 9.7kWh capacity suits most UK households (average daily consumption 8–10kWh). The 10-year warranty is competitive. The LFP chemistry gives a realistic 15+ year lifespan at daily cycling rates. At £3,000–£4,000 before installation, it's expensive per kWh versus DIY LFP alternatives — but the integration premium is real and the installer infrastructure is mature.
For everyone else
If you don't have SolarEdge inverters, stop reading and look at the Pylontech US5000 review instead. This product doesn't exist for you.
The verdict
SolarEdge Home Battery: the right battery for SolarEdge owners, irrelevant for everyone else. Good hardware, mature ecosystem, premium pricing. Exactly what you'd expect from SolarEdge.
