Description
GoodWe ESA 15kWh Battery Storage All-In-One System 20kW combines a three-phase 20 kW hybrid inverter and 15.36 kWh usable LiFePO4 storage in a pre-wired system. This lets you use your solar power throughout the day and cover the evening and nighttime hours from your own reserves.
Your Advantages at a Glance
More independence: 15.36 kWh of storage capacity increases your self-consumption and reduces grid power draw.
Backup-ready: The dual-port design switches to backup operation in under 4 ms in the event of a grid outage.
Robust and durable: IP66 protection and LiFePO4 cells with ≥ 8000 charge cycles ensure reliable continuous operation.
Expandable: The battery storage can be expanded with up to 12 battery modules to suit your future needs.
The System in Detail
The Hybrid Inverter
The GoodWe ESA GW20K-ETA-G20 is a three-phase hybrid inverter with 20 kW rated power and 4 MPP trackers. It handles up to 40 kW of PV input power, allowing for a generously sized photovoltaic system. Via the backup port, it continues to supply your loads during a grid outage, with a switchover time of under 4 ms. Intelligent fan cooling and IP66 protection enable quiet, weather-resistant operation.
The Battery Storage
Three GoodWe ESA GW5.1-BAT-D-G20 battery modules, each with 5.12 kWh of rated energy, form a high-voltage storage system with a total of 15.36 kWh. LiFePO4 technology stands for a proven chemistry with ≥ 8000 charge cycles. An integrated heating system and aerosol fire suppression ensure safe operation even at low temperatures. The storage system can be expanded at any time to up to 12 modules.
