The SOL IA-S4 series consists of 3.5kW and 5kW 48V pure sine wave off-grid inverters, designed for small residential standalone solar power solutions. This unit adopts multi-energy complementary power supply logic: municipal grid power will automatically supplement loads when solar PV generation is insufficient. Users can freely customize power source priority and set scheduled charging & discharging periods to maximize solar self-consumption efficiency. It supports two flexible operation modes, running stably either equipped with storage batteries or without batteries. Up to 9 inverters can be paralleled to reach a combined maximum capacity of 45kW, with a maximum PV input voltage of 500VDC compatible with mainstream solar panels. Lightweight compact body with IP20 protection fits indoor wall-mounted installation, ideal for countryside houses, remote cabins and family emergency backup power.
