GoodWe ESA 20 kW Inverter with All-in-One Storage System

GoodWe ESA 20 kW All-In-One Energy Storage System

Modern All-in-One Solution for PV, Storage, and Backup Applications

The GoodWe ESA 20 kW All-In-One System is a modern and powerful all-in-one solution for photovoltaics, energy storage, and intelligent energy management. This three-phase high-voltage system combines a hybrid inverter, battery storage, and backup function in a compact unit, making it ideal for private households and small commercial applications.

Thanks to its modular system architecture, the battery capacity can be flexibly expanded from 5 to 108 kWh and optimally adapted to individual energy needs. The combination of modern LiFePO4 battery technology, high energy efficiency, and intelligent control enables maximum self-consumption rates and a reliable energy supply.

With PV oversizing of up to 200%, multiple MPPTs, and the ability to simultaneously power consumers and charge the battery, the ESA system ensures optimal utilization of your solar energy. The integrated emergency power and backup function with a switching time of ≤ 4 ms also guarantees an uninterruptible power supply even in the event of a grid failure.

Additional safety features such as AFCI arc fault detection, integrated AC/DC Type 2 surge protection, intelligent battery management, and an integrated fire protection system ensure maximum operational safety.

Thanks to WLAN, LAN, Bluetooth, and RS485, as well as the GoodWe SEMS+ platform, the system can be conveniently monitored and intelligently controlled. With its compact design, flexible wall or floor mounting, and high scalability, the GoodWe ESA System is the ideal solution for future-proof PV and storage projects in residential and commercial sectors.
