125kW 225kWh / 241kWh All-in-One
Commercial & Industrial BESS Cabinet
The BSLBATT ESS-GRID C225/C241 is a standard commercial and industrial energy storage cabinet available in 225kWh and 241kWh capacities. Built with 314Ah LFP cells and a 125kW integrated inverter, it supports peak shaving, backup power, demand response, and increased PV self-consumption. Up to 4 units can be connected in parallel for large-scale deployment.
All-in-One Integrated Energy Storage System Design Inside the Cabinet
BSLBATT Commercial solar battery system boasts outstanding performance, making it versatile for applications in farms, livestock, hotels, schools, warehouses, communities, and solar parks. It supports grid-tied, off-grid, and hybrid solar systems, and can be used with diesel generators. The ESS-GRID series is available in 225kWh and 241kWh configurations, both powered by 314Ah LFP cells.
Compartmentalized Design
The BSLBATT 200kWh Battery Cabinet utilizes a design that separates the battery pack from the electrical unit, increasing the safety of the cabinet for energy storage batteries.
3 Level Fire Safety System
BSLBATT C&I ESS Battery has the world's leading battery management technology, including dual integration of active and passive fire protection, and the product setup has PACK level fire protection, group level fire protection, and dual-compartment level fire protection.
