Collection: High Voltage Storage Batteries

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

High voltage pays off above 20-30kWh and on three-phase installations: at the same power the current drops by a factor of four or five against 48V, so losses, cable sizes and contactor ratings all come down. The trade is a string BMS and more care over safety.

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