Description du produit :

The SW-20Kw40kWh is an all-in-one outdoor energy storage solution built for commercial and industrial facilities, microgrids, and PV+ESS+charging projects. At its core is a 40 kWh LFP battery bank (100 Ah cells, 1P128S, 409 V) paired with a 20 kW rated AC output and 0.5C charge/discharge capability. The system accepts up to 30 kW of PV input through two MPPT channels (200–960 V), so solar power can be stored and dispatched directly on site.

With under 20 ms on/off-grid switching, critical loads stay powered through grid disturbances, and 100% unbalanced three-phase load support keeps operation stable in real-world conditions. The cabinet is engineered for outdoor life: air-cooled thermal management, IP54 protection, aerosol fire suppression, and intelligent dehumidification reduce maintenance and extend service life. Multiple units can run in parallel as energy needs grow, while remote cloud EMS provides monitoring, upgrades, and cloud-based operations over RS485/Ethernet with Modbus — making SW-20Kw40kWh a flexible, low-maintenance foundation for distributed energy storage.
