Description

GoodWe ESA 10kWh Battery Storage All-In-One System 15kW combines a three-phase hybrid inverter and a high-voltage battery storage system in a pre-wired, modular unit. With 15 kW inverter power and 10.24 kWh nominal energy, the GoodWe ESA All-in-One System is suitable for households and small commercial operations that want to store their solar power and increase their self-consumption.

Your benefits at a glance

Backup power capable: The dual-port design enables backup power supply with seamless switchover in under 4 ms.
High safety: LFP battery technology with 6-stage safety protection, integrated aerosol fire suppression, and IP66 protection rating.
Long service life: The battery modules are rated for at least 8,000 charge cycles.
Expandable: The storage system can be expanded with additional ESA series modules up to 108 kWh.

The system in detail

The inverter

The GoodWe ESA GW15K-ETA-G20 is a three-phase hybrid inverter with 15 kW nominal power. It features four MPP trackers and a maximum PV input power of 30 kW, enabling DC oversizing. With a maximum efficiency of 98.1%, it converts the generated solar power with low losses. The integrated backup port ensures a backup power supply with a switchover time of under 4 ms. Communication and monitoring take place via WiFi, LAN, and Bluetooth through the app.

The battery storage

Two GoodWe ESA GW5.1-BAT-D-G20 battery modules form the high-voltage storage of this system. Each module delivers 5.12 kWh nominal energy and 5.0 kWh usable energy, for a total of 10.24 kWh. The modules are based on lithium iron phosphate (LFP) and are rated for at least 8,000 charge cycles. An integrated heater ensures operation even at low temperatures, and aerosol fire suppression increases safety. The storage system can be modularly expanded to up to 12 modules.
