The 14–18kW platform remains a 48V nominal battery system, so DC current becomes high as inverter power rises. Two battery input paths provide a more practical connection architecture for that current, and the 18kW model supports up to 350A charge/discharge. A 48V inverter at this scale requires batteries, busbars, conductors, fuses and disconnects that are designed together. Two inputs help distribute connection paths, but they do not make undersized battery wiring or an under-rated BMS acceptable.
