Battery module – GOODWE – GW8.3-BAT-D-G20 – 8.3 kWh – HV

ESA

ESA by GoodWe is a three-phase all-in-one energy storage system combining an inverter, an LFP (LiFePO₄) battery and intelligent energy management. Its pre-wired, modular design streamlines setup and speeds up commissioning. The series offers power ratings of 5–30 kW and allows storage capacity expansion up to 108 kWh, depending on the configuration.

Key advantages of ESA

• Expansion to up to 12 battery modules per inverter, with the option of combining batteries of different capacities as well as new and used batteries. In a single-column installation, the limit is 6 modules.
• Whole-home backup power thanks to its dual-port design and switching to backup power in under 4 ms.
• Intelligent energy management with readiness to support an AI-based EMS system and optimization based on dynamic tariffs.
• Parallel operation both in grid-connected and off-grid modes.
• 6-layer safety protection, AI-based AFCI 3.0 protection and an IP66 protection rating.
• Integrated heating and aerosol fire suppression in battery modules; the discharge temperature range is from -20 to +55°C.

Who is this a good choice for?

ESA is designed for households requiring energy storage and whole-home backup power, as well as businesses operating small commercial facilities that want expandable capacity and intelligent energy management. Selecting the inverter power and number of modules allows the system configuration to be tailored, with the maximum charging and discharging power of the entire storage system limited by the inverter, not the combined power of the battery modules.
