Description

GoodWe ESA 20kWh Battery Storage All-In-One System 6kW combines a three-phase hybrid inverter, battery storage, and intelligent energy management in one pre-wired unit. With 20.48 kWh of LFP storage capacity and 6 kW AC output, this system reliably powers your home with self-generated solar energy - even when the sun isn't shining.

Your Benefits at a Glance

More independence: 20.48 kWh of storage capacity enables a high self-consumption rate of your photovoltaic power.
Backup power capable: Seamless switchover to backup in under 4 milliseconds during a grid outage.
High safety: 6-level safety protection, IP66, integrated aerosol fire suppression, and heating mode down to -20 °C.
Designed for long-term use: The LFP battery modules are rated by the manufacturer at ≥ 8000 charge cycles.

The System in Detail

The Hybrid Inverter

The GoodWe ESA GW6K-ETA-G20 is a three-phase hybrid inverter with 6 kW rated power and three MPP trackers. It handles up to 12 kW of PV input power, enabling DC oversizing of up to 200%. Via the backup port, it delivers up to 63 A of through-current in grid-tied operation for a whole-home backup solution. Maximum efficiency is 98.0%, with cooling provided by intelligent, low-noise fan control.

The Battery Storage

Four GoodWe ESA GW5.1-BAT-D-G20 battery modules form the storage of this system. Each module is based on lithium iron phosphate (LFP/LiFePO4) and offers 5.12 kWh of rated energy, totaling 20.48 kWh. The modules feature integrated heating as well as aerosol fire suppression and are protected against dust and water to IP66. The all-in-one system of the ESA series can be expanded to up to 12 modules - so your system can grow with increasing demand later on, without needing to be replaced.
