The H series is a range of highly integrated, containerized medium-scale microgrid energy storage systems designed for commercial & industrial, PV+ESS+charging, microgrid, and grid-side applications. The SW-H10-250kW482kWh and SW-H10-250kW732kWh deliver 250 kW rated AC output with 482 kWh and 723 kWh of LiFePO4 storage respectively, while the SW-H20-500kW1205kWh steps up to 500 kW output and 1205 kWh capacity. All three models use 314 Ah LFP cells with 0.5C charge/discharge, support 100% unbalanced three-phase loads, and switch seamlessly between on-grid and off-grid operation for backup power and black-start capability.

Each system is PV-ready with DC-coupled PV input — up to 360 kWp (external) on the H10 models and 720 kWp on the H20 model — and coordinates multiple power sources including PV, grid, load, and generator. Built in a standard container design for easy shipping, the cabinets are highly integrated and plug-and-play, with IP54 protection, intelligent dehumidification, isolation transformers on the H-series models, and liquid-cooled battery compartments on the H10 series to ensure reliable outdoor operation. Communication via RS485/Ethernet with Modbus and IEC104 supports remote monitoring, cloud EMS, and remote upgrades — making the H series a complete, scalable solution for medium-scale microgrids.
