GoodWe launches scalable C&I battery system with 100 kWh+ capacity

GoodWe has introduced its new BAT series high-voltage battery cabinet for the commercial and industrial (C&I) sector. The system is available in two capacities, 102.4 kWh and 112.6 kWh, which are achieved by using a different number of the same standard battery packs. The smaller cabinet contains ten packs while the larger contains eleven.

This difference in pack count also results in different nominal system voltages, 512V and 563.2V respectively, allowing for flexibility in system design. The battery is designed to pair with the company’s ET series hybrid inverters, initially integrating with the ET50kW model to create a 50kW/100kWh energy storage solution for small to medium C&I installations.

“Businesses are facing rising electricity costs, an urgent need for energy resilience and setting ambitious decarbonization goals. The new BAT system is the ideal solution to these challenges, enabling companies to reduce peak demand charges, maximize solar self-consumption, and ensure uninterrupted operations during grid outages,” says Jie Zhang, managing director of GoodWe Europe.

The system uses Lithium Iron Phosphate (LiFePO4​) cells and is rated for a 6000 cycle life and GoodWe is marketing it as design for outdoors. For durability, the cabinet has an IP55 protection rating and a C4 corrosion resistance rating. An integrated HVAC system maintains cell temperature variance below 3°C and allows operation from −25°C to 55°C. Safety features include electrical protections and an aerosol fire suppression system. The battery has a continuous charge rate of 0.9C and a discharge rate of 1.1C.

The system is scalable up to 450 kWh by paralleling four battery units. Multiple inverters can also be paralleled for configurations up to 500 kW / 4.5 MWh. GoodWe stated a compatible 100 kW ET series inverter is planned for future release.
