Lithium-ion batteries offer high energy density, long cycle life, fast charging capability, and compact size. They are ideal for commercial and industrial storage where space efficiency, performance, and safety are critical.
By charging during off-peak hours and discharging during peak demand, the system minimizes electricity bills. It also reduces demand charges by flattening peak loads, and supports participation in demand response programs for additional revenue.
Most C&I lithium-ion systems are designed for 6,000–10,000 cycles or 10–15 years of service life, depending on usage conditions, charge/discharge depth, and maintenance. Advanced BMS ensures safe and efficient lifecycle management.
Yes. When configured for backup or off-grid operation, the system can automatically switch to island mode and supply critical loads during outages, ensuring business continuity and power security.
C&I BESS solutions are modular and scalable. Additional battery modules or PCS units can be added as energy demand grows, allowing flexible expansion without replacing the entire system.
