SolarEdge Home Battery 48V - Overview
The SolarEdge Home Battery 48V is a 9.7 kWh LFP battery designed exclusively for use with the SolarEdge Energy Hub inverter. DC coupling - where the battery charges directly from the solar array's DC output rather than via AC - delivers a round-trip efficiency above 94.5%, meaningfully higher than AC-coupled alternatives (typically 89 - 92%). For systems where the battery will cycle daily from solar, this efficiency advantage compounds into measurable additional annual yield.
DC Coupling Efficiency Advantage
In an AC-coupled system (such as Enphase IQ Battery), solar DC is converted to AC by the inverter, then back to DC for battery storage, then to AC again for load supply - three conversions, each losing 3 - 5%. In DC coupling, solar DC charges the battery directly, then converts to AC once for load supply. For a system cycling 9.7 kWh/day at $0.30/kWh, the 5% round-trip efficiency advantage saves approximately $53/year.
SolarEdge Energy Hub Integration
The Home Battery requires the SolarEdge Energy Hub inverter (not compatible with standard SE6000H or other SolarEdge inverters). The Energy Hub provides a unified interface for solar production, battery state-of-charge, grid import/export, and EV charging - all manageable from the mySolarEdge app. The system can be configured for self-consumption maximisation, time-of-use arbitrage, or backup power priority.
Modular Architecture
A single Home Battery provides 9.7 kWh. Up to three units can be connected per Energy Hub inverter for up to 29.1 kWh total storage - sufficient for homes with EV charging loads or multi-day backup requirements.
Key Advantages
- DC-coupled efficiency - >94.5% round-trip, the best in residential battery storage
- LFP chemistry - no thermal runaway, longer cycle life than NMC
- 9.7 kWh per unit - modular stacking to 29.1 kWh
- Energy Hub integration - unified solar + battery + EV management in one inverter
- Indoor rated - 0 deg C minimum charge temperature; suited for temperate climates with a heated utility room
