30 dB*
*5-8 kW｜Operating noise as low as 30 dB at 25 °C ambient
The GoodWe ESA Series 5-30 kW/5-108 kWh is a three-phase All-in-One ESS that integrates the inverter, battery, and intelligent energy management into a single system. Its pre-wired, modular design unifies the inverter and battery, delivering an installation-friendly structure that streamlines setup and accelerates commissioning. With four battery module options—5, 6*, 8, and 9* kWh—up to 12 modules can be connected for a total storage capacity of 108 kWh. Featuring simplified configuration, large expandable storage, and an AI-driven EMS for dynamic tariff optimization, the ESA Series 5–30kW/5–108kWh provides an efficient, flexible, and future-ready solution for both residential and small commercial use.
