GoodWe ESA 261kWh C&I All-in-One ESS
GoodWe ESA 261kWh battery + 125 kW AC Inverter + C4 Protection
The GoodWe GW125/261-ESA-LCN-G10 is a
fully integrated C&I all-in-one energy storage system designed for
larger commercial and industrial projects. With 125 kW output and
approximately 261 kWh usable energy, it combines the battery, PCS,
EMS and BMS in one outdoor cabinet.
Its liquid-cooled design supports stable operation in demanding environments, while the integrated architecture helps simplify installation, operation and maintenance. The system is suitable for backup power, peak shaving, self-consumption optimisation, demand control, load management, energy trading applications and off-grid backup.
For scalable C&I projects, multiple ESA
units can operate in parallel. The system supports up to 20 units in
parallel, reaching up to 2.5 MW / 5.22 MWh.

Why Choose
the ESA ESS?Â
The GoodWe ESA ESS is designed for projects that require a pre-integrated C&I energy storage system rather than a separate battery cabinet and inverter setup. The GW125/261-ESA-LCN-G10 combines the battery, PCS, EMS and BMS in one cabinet, making it suitable for applications where simplified installation, integrated control and high storage capacity in a compact footprint are priorities.
With a footprint of only 1.47 m² and an energy density of 177.6 kWh/m², the ESA cabinet is well-suited to sites where space is limited. Its liquid-cooled design and multi-level protection help support stable operation in demanding C&I environments.
For projects requiring a more flexible battery cabinet solution built around GoodWe ET hybrid inverters, the GoodWe BAT-C is available as an alternative, including the 112.6kWh GW112.6-BAT-AC-G10 model.
