Description

GoodWe ESA 20kWh Battery Storage All-In-One System 29.9kW combines a three-phase hybrid inverter and high-voltage battery storage in one pre-wired system. With 29.9 kW AC output and 20 kWh usable storage capacity, this GoodWe storage system covers the self-consumption needs of ambitious households and small businesses, while also providing backup power when needed.

Your Benefits at a Glance

More self-consumption: 20 kWh usable capacity stores solar power generated during the day for use in the evening and at night.
Backup-power capable: The dual-port design with a switching time of under 4 ms keeps your home powered even during a grid outage.
High safety: 6-level safety protection, IP66, and integrated aerosol fire suppression reliably protect the system.
Future-proof: The battery storage can be expanded from 20 kWh up to 108 kWh (12 modules).

The System in Detail

The Hybrid Inverter

The GoodWe ESA GW29.999K-ETA-G20 is a three-phase hybrid inverter with a rated output of 29.999 kW and a maximum efficiency of 98.2%. It features four MPP trackers and can accept up to 60 kW of PV power, enabling generous DC oversizing. Thanks to its dual-port design and a switching time of under 4 ms, it ensures reliable backup power for the entire house.

The Battery Storage

Four GoodWe ESA GW5.1-BAT-D-G20 battery modules form the high-voltage (HV) storage of this system. Each LFP-based (LiFePO4) module offers 5.12 kWh rated energy and 5.0 kWh usable energy, for a total of 20 kWh usable. The integrated heating ensures reliable operation even at low temperatures, while the aerosol fire suppression provides additional safety. With a cycle life of ≥ 8000 cycles, the GoodWe battery storage is designed for many years of use.
