Description

GoodWe ESA 25kWh Battery Storage All-In-One System 15kW combines a hybrid inverter and battery storage in one pre-wired, three-phase system for residential and small commercial use. With 25.6 kWh usable storage capacity and 15 kW inverter power, you can use your solar power efficiently and become more independent from the public grid.

Your Benefits at a Glance

Large energy reserve: Five battery modules jointly store around 25.6 kWh of solar power for evenings, nights, and cloudy days.
Backup power capable: The dual-port design switches to backup power in under 4 milliseconds in the event of a grid outage.
High safety: Each battery module features an integrated heater and aerosol fire suppression, as well as IP66 protection.
Modularly expandable: The ESA series can be expanded to up to 12 modules – your system grows with your needs.

The System in Detail

The Hybrid Inverter

The GoodWe ESA GW15K-ETA-G20 is a three-phase hybrid inverter with 15 kW AC rated power. It features four MPP trackers and accepts up to 30 kW of PV input power, allowing for DC oversizing of up to 200%. With a maximum efficiency of 98.1% and integrated AFCI arc-fault protection, it operates safely and efficiently. Intelligent energy management automatically controls charging, discharging, and grid draw in the background.

The Battery Storage

The storage consists of five GoodWe ESA GW5.1-BAT-D-G20 battery modules, each with 5.12 kWh rated energy (5.0 kWh usable), for a combined total of around 25.6 kWh rated energy. The modules use durable lithium iron phosphate (LFP) cells and are rated for at least 8,000 charge cycles. As high-voltage (HV) storage, they operate in the three-phase system within a voltage range of 700 to 950 V. Each module includes an integrated heater and aerosol fire suppression, and allows operation down to -20 °C.
