GoodWe ESA Home Battery

Home > Solar Battery > GoodWe ESA Series Battery

The GoodWe ESA is a reliable and scalable all-in-one residential storage solution. It combines a solar battery, a hybrid inverter and energy management into a single system.

All-In-One Storage Solution

The GoodWe ESA Series simplifies home energy by combining an inverter and battery into one pre-wired, modular system. A standard system setup requires selecting and installing each individual component. The ESA is a fully integrated system, making installation faster and monitoring less complex.

Stackable Design, Limitless Possibilities

The ESA is designed with flexibility in mind. It allows for seamless expansion of your solar storage to meet evolving energy needs. The system uses 5kWh and 8kWh battery modules. You can mix these module sizes and connect a total of 12 within a single stack to reach up to 108kWh.

Reliable Whole-Home Backup

One of the standout features of the ESA battery is its ability to provide UPS-level, full-house backup without the need for a gateway. This means your home stays powered during outages with seamless transitions to backup power in under 4 milliseconds. This means your lights and appliances will stay running in the event of a blackout, storm and grid maintenance.

Optimised Performance

The ESA energy storage system is engineered for high efficiency and fast energy response, featuring a 1 Cell charge/discharge rate that enables rapid energy cycling. With support for 20A input per string and up to 200% PV oversizing, it maximises solar energy utilisation even under varying conditions.
