Description

GoodWe ESA 15kWh Battery Storage All-In-One System 6kW combines a three-phase hybrid inverter and a modular LFP battery storage into a perfectly matched unit for your home. With 6 kW inverter power and 15.36 kWh rated capacity, you can use your solar power even when the sun isn't shining.

Your benefits at a glance

More self-consumption: 15.36 kWh of storage capacity makes solar power generated during the day available in the evening and at night.
Backup-power capable: The dual-port backup switches to backup power in under 4 ms and bridges grid outages.
Robust and durable: IP66 protection and LiFePO4 cells with a cycle life of ≥ 8000 cycles ensure reliable continuous operation.
Future-proof: Up to 12 battery modules can be connected per system, so you can add more storage later.

The system in detail

The hybrid inverter

The heart of the system is the GoodWe ESA GW6K-ETA-G20, a three-phase all-in-one inverter with a rated power of 6 kW. It features three MPP trackers and a maximum PV input power of 12 kW, allowing you to connect your photovoltaic modules flexibly. With a maximum efficiency of 98.0%, it operates with minimal losses. The integrated bypass function with a 63 A through-current enables backup power supply, and intelligent fan cooling keeps operation quiet. Monitoring and configuration are conveniently done via app over WiFi, LAN, or Bluetooth.

The battery storage

The storage consists of three GoodWe ESA GW5.1-BAT-D-G20 battery modules, each with 5.12 kWh rated energy, totaling 15.36 kWh. The modules use safe LiFePO4 cell chemistry and are designed for a cycle life of ≥ 8000 cycles. An integrated heater and integrated aerosol fire suppression increase operational safety, while the IP66 protection rating guards against dust and water. Up to 12 modules can be combined per system, so you can expand your storage later as your needs grow.
