Description

GoodWe ESA 25kWh Battery Storage All-In-One System 8kW combines inverter, storage, and energy management in one three-phase complete system. With approximately 25.6 kWh of storage capacity and an 8 kW hybrid inverter, it reliably supplies your home with self-generated solar power - even in the evening and at night.

Your advantages at a glance

High self-sufficiency: With approximately 25.6 kWh of capacity, you store large amounts of solar power for use after sunset.
Backup power capable: Thanks to the dual-port design and a switchover time of under 4 ms, your household stays powered even during a grid outage.
Robust and safe: LFP technology, an integrated aerosol fire suppression system, and IP66 protection ensure safe operation.
Modularly expandable: The ESA series supports up to 12 battery modules - this system with 5 modules can be expanded later.

The system in detail

The hybrid inverter

The GoodWe ESA GW8K-ETA-G20 is a three-phase hybrid inverter with a rated output of 8 kW. It features three MPP trackers, a maximum PV input power of 16 kW, and achieves a maximum efficiency of 98.0%. Via the backup port, it provides up to 43.5 kVA in grid-connected operation and 8.8 kVA in off-grid operation. A 6-level safety protection system, AFCI, and IP66 protection ensure reliable operation.

The battery storage

Five GoodWe ESA GW5.1-BAT-D-G20 battery modules form the storage of this system. Each LFP-based (LiFePO4) module offers 5.12 kWh of rated energy and 5.0 kWh of usable energy - together resulting in approximately 25.6 kWh of rated energy. An integrated heater enables operation even at low temperatures, and the integrated aerosol fire suppression system increases safety. The manufacturer states a cycle life of at least 8000 cycles.
