Description

GoodWe ESA 10kWh Battery Storage All-In-One System 12kW combines a three-phase hybrid inverter and a high-voltage battery storage unit in one pre-wired system. With 12 kW of inverter power and 10.24 kWh nominal capacity (10.0 kWh usable), you can store your solar power and use it whenever your family needs it.

Your advantages at a glance

Backup power capable: Thanks to the backup port and a switchover time of under 4 ms, your home stays powered even during a grid outage.
High safety: Advanced 6-level safety protection, LFP technology, and integrated heating and aerosol fire suppression.
Long service life: The LFP battery modules are rated for ≥ 8000 charge cycles and operate reliably for the long term.
Expandable later: The ESA series can be expanded with additional battery modules for greater capacity.

The system in detail

The hybrid inverter

The GoodWe ESA GW12K-ETA-G20 is a three-phase hybrid inverter with 12 kW nominal power and a maximum efficiency of 98.1%. It features four MPP trackers and up to 24 kW of PV input power, allowing you to size your photovoltaic system generously. Via the backup port, the inverter continues to supply your loads during a grid outage. Comprehensive protection features such as AFCI, anti-islanding protection, and a DC switch are already integrated.

The battery storage

Two GoodWe ESA GW5.1-BAT-D-G20 battery modules form the high-voltage storage of this system. Each module provides 5.12 kWh of nominal energy (5.0 kWh usable), for a combined total of 10.24 kWh. The modules use long-lasting lithium iron phosphate (LFP) cells and are rated for ≥ 8000 charge cycles. Heating and aerosol fire suppression are integrated into each module, so the storage works reliably even at low temperatures. The capacity can be expanded later if needed.
