LiFePO4 High-Voltage Battery Storage System for Commercial Solar Solutions
The ESS-GRID S280 is an indoor fixed storage system based on LiFePO4 technology, designed to meet the commercial solar storage needs of applications like solar parks, schools, and small factories. This high-voltage battery system offers voltage ranges from 512V to 819V and is compatible with high-voltage 3-phase inverters for energy management, backup power, and bill savings. With battery capacities ranging from 143 kWh to 229 kWh, it is built for reliable, long-lasting power in industrial and commercial operations.
Powered by EVE 3.2V 280Ah lithium iron phosphate cells, the ESS-GRID S280 features BSLBATT’s carrier-grade battery modules, ensuring a lifespan of up to 15 years and more than 6,000 cycles. The ESS-GRID Station series also includes a master-slave multi-tier battery management system (BMS) for proactive monitoring, optimization, and balancing of battery performance.
