SW-186kW372kWh and SW-209kW418kWh are high-capacity outdoor energy storage cabinets engineered for commercial & industrial, grid-side, PV+ESS+charging, and microgrid applications. Both models use long-life LiFePO4 cells in a 1P416S configuration with a rated system voltage of 1331.2 V, support 0.5C charge/discharge, and provide rated AC output of 186 kW and 209 kW respectively at a 690 V grid voltage. With rated capacities of 372.73 kWh and 417.99 kWh, the series delivers up to 418 kWh in a single cabinet for high-density deployments.

Built for outdoor reliability and easy installation, both cabinets combine pack-level liquid cooling with air-cooled electrical compartments, IP54 ingress protection, and dual fire protection using aerosol or perfluorohexanone. Intelligent dehumidification eliminates condensation risk, while flexible expansion and parallel operation let the system grow with demand. Communication via RS485/CAN with Modbus and IEC104 protocols supports remote monitoring, cloud operations, and seamless integration into larger energy management systems — making the LES series a complete, scalable solution for large-scale distributed energy storage.
