Description

GoodWe ESA 10kWh Battery Storage All-In-One System 20kW combines a hybrid inverter and battery storage in one pre-wired, three-phase system. With 20 kW inverter power and 10.24 kWh usable LFP capacity, the set reliably supplies households and small commercial businesses with their own power.

Your Benefits at a Glance

More independence: The battery storage makes power generated during the day available in the evening and at night as well.
Backup power capable: The dual-port design supplies critical loads in the event of a grid outage, with a switchover time of under 4 ms.
High safety: LFP technology with IP66 protection, 6-level safety protection, and integrated aerosol fire suppression.
Expandable: The battery storage can be expanded to a larger capacity with additional battery modules.

The System in Detail

The Hybrid 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 power, allowing for generous DC oversizing. The integrated backup port enables backup power supply, and intelligent fan cooling ensures quiet operation. The maximum efficiency is 98.1%.

The Battery Storage

Two GoodWe ESA GW5.1-BAT-D-G20 battery modules form the high-voltage battery storage. Each module provides 5.12 kWh of rated energy and 5.0 kWh of usable energy, for a total of 10.24 kWh rated energy. The cells are based on lithium iron phosphate (LFP) and are rated for at least 8,000 charge cycles. An integrated heating mode and aerosol fire suppression contribute to safe operation.
