Outdoor Cabinet ESS 50kW 112kWh

SW-50kW112kWh is a 50 kW / 112 kWh outdoor energy storage cabinet with air-cooled design, up to 100 kW of PV input, and fast on/off-grid switching — built for C&I storage, microgrids, and PV+ESS+charging applications.

Rated Output Power	50 kW
Rated Energy	112 kWh
Max. PV Input Power	100 kWp
IP Rating	IP54

SW-50kW112kWh is an outdoor, PV-ready energy storage cabinet designed for commercial and industrial applications, microgrids, and PV+ESS+charging scenarios. It combines a 50 kW rated AC output with a 112 kWh LFP battery bank (314 Ah cells, 1P112S, 358 V), supports 0.5C charge/discharge, and accepts up to 100 kW of PV input through 4 MPPT channels (200–950 V). A built-in generator input (up to 60 kVA) adds flexibility for sites with backup generators, while on-grid and off-grid operation with under 20 ms switching keeps critical loads powered through grid disturbances.

The cabinet is built for outdoor deployment and low-maintenance operation: air-cooled thermal management, IP54 protection, and a dual fire protection system combining aerosol and water-based suppression protect the system in demanding environments. It supports unbalanced three-phase loads and parallel units for flexible expansion, and remote cloud EMS enables monitoring and upgrades over RS485/Ethernet with Modbus — making SW-50kW112kWh a complete, scalable solution for distributed energy storage.
