Description

GoodWe ESA 25kWh Battery Storage All-In-One System 20kW combines a three-phase 20 kW hybrid inverter with a stackable LFP battery storage system to create a compact energy hub for your home. With a total usable capacity of around 25.6 kWh, you can use your solar power even when the sun isn't shining, gaining a significant degree of independence from the public grid.

Your benefits at a glance

High storage capacity: Five battery modules provide around 25.6 kWh of rated energy for your self-consumption in the evening and at night.
Backup power capable: The dual-port design with a switching time of under 4 ms reliably keeps your home powered during a grid outage.
High safety: Each module features an integrated heater and aerosol fire suppression, and the battery storage is protected to IP66.
Expandable: The ESA series holds up to 12 modules, so you can adapt the battery storage to your needs later on.

The system in detail

The inverter

The GoodWe ESA GW20K-ETA-G20 is a three-phase hybrid inverter with 20 kW rated power. It features four MPP trackers and accepts up to 40 kW of PV input, allowing for significant DC oversizing. Via the backup port, it secures backup power supply, switching to island mode in under 4 ms. With a maximum efficiency of 98.1% and intelligent fan cooling, the unit operates efficiently and quietly.

The battery storage

Five GoodWe ESA GW5.1-BAT-D-G20 battery modules form the heart of the storage system. Each module is based on safe lithium iron phosphate (LFP) technology and delivers 5.12 kWh of rated energy, for a total of around 25.6 kWh. The modules are stacked in a space-saving design and are equipped with integrated heating and aerosol fire suppression. With a cycle life of at least 8,000 cycles, the system is designed for many years of operation. Since a system like this has no moving parts, it operates independently in everyday use and requires no refilling or regular maintenance from you.
