Collection: High-Voltage Storage Batteries

High voltage storage batteries, with clusters above 200V reaching beyond 800V: Felicity FLH rack modules of 5.12 kWh, heated IP65 versions for outdoors, stackable Marstek Mars I Plus of 5.12 kWh, heated Dyness S51280 of 14.3 kWh and the BMS control modules needed to manage the string.

High voltage pays above 20-30 kWh and on three-phase systems: at the same power the current drops by a factor of four or five compared with 48V, cutting losses, cable sizes and contactor ratings. In exchange you need a string BMS and greater care on safety.

Modules stack or rack mount up to the capacity required, with CAN communication to the hybrid inverter or the PCS.
