BESS-100-261K 100kW commercial battery system is a next-generation outdoor energy storage solution designed for industrial and commercial applications. Built with advanced lithium battery technology and an integrated Power Conversion System (PCS), it delivers reliable, scalable, and efficient energy management.
Optimized for harsh environments, this commercial battery energy storage system meets IP54 or higher protection standards. It operates efficiently across a wide temperature range (-20°C to +55°C). This makes it ideal for factories, solar farms, microgrids, telecom towers, and EV charging hubs.

A 100kW commercial battery system is an energy storage solution capable of delivering 100 kilowatts of power output, typically used in:
It stores electricity (from grid or solar) and releases it when needed, helping businesses reduce electricity costs and improve energy reliability.
The BESS-100-261K outdoor battery storage system comes with a built-in PCS, eliminating the need for external inverters. This ensures:
Designed for outdoor environments, the system features an IP55-rated enclosure that protects against:
Perfect for deployment in factories, solar farms, and remote sites.
With a large storage capacity, this 261kWh battery energy storage system ensures:
Utility demand charges often account for 30-70% of a factory’s electricity bill. The commercial bess releases stored energy during high-demand peaks. This reduces the facility’s maximum demand (kW) from the grid. It also lowers monthly utility expenses.
Supports multiple communication protocols such as:
This enables seamless integration with EMS (Energy Management Systems) and remote monitoring platforms.
Shift energy usage from peak-rate hours to off-peak periods using stored solar or grid power—reducing demand charges significantly.
Smooth solar intermittency and maximize self-consumption of on-site renewables, accelerating your net-zero goals.
Modular architecture allows easy capacity upgrades as your energy needs grow—no need to replace the entire system.
