Description

GoodWe ESA 25kWh Battery Storage All-In-One System 12kW combines a three-phase 12 kW hybrid inverter with a battery storage system made up of five modules into a pre-configured complete solution. With a storage capacity of around 25.6 kWh, this system offers plenty of reserve to store your solar power and use it whenever you need it.

Your Benefits at a Glance

High self-sufficiency: Around 25.6 kWh of storage capacity provides a large buffer of your own solar power for evening and night.
Backup power capable: The dual-port design enables backup power supply with a switchover time of less than 4 ms.
Robust safety: Integrated heating, aerosol fire suppression, and IP66 protection ensure reliable operation even at -20 °C.
Long service life: The LFP battery modules are rated for ≥ 8000 charge cycles.

The System in Detail

The Hybrid Inverter

The GoodWe ESA GW12K-ETA-G20 is a three-phase all-in-one hybrid inverter with a rated AC output of 12 kW. It features four MPP trackers and a maximum PV input power of 24 kW, allowing for generous DC oversizing of your photovoltaic system. With a maximum efficiency of 98.1%, integrated AFCI arc-fault protection, and a wide range of protective functions, the GoodWe inverter operates efficiently and safely. Connectivity is provided via RS485, Wi-Fi, LAN, and Bluetooth.

The Battery Storage

The storage system consists of five GoodWe ESA GW5.1-BAT-D-G20 battery modules, each with 5.12 kWh of rated energy and 5.0 kWh of usable energy per module. In total, this provides around 25.6 kWh of rated energy, or 25 kWh of usable capacity. The LFP modules (LiFePO4) are rated for ≥ 8000 charge cycles and are stacked to save space. Integrated heating and aerosol fire suppression, along with IP66 protection, ensure the safe operation of this GoodWe battery storage system for many years.
