$11/kW
Model: EG4-3000EHV-48
The EG4 3000EHV-48 is a compact multi-function inverter/charger combining a 3000W pure sine wave inverter, MPPT solar charger, and battery charger. It accepts a 48V battery bank, supports up to 5000W of PV input and 500VDC maximum PV open-circuit voltage, and includes an LCD display, RS232/RS485 communications, parallel capability, and a built-in Wi-Fi communications dongle. It is intended for off-grid applications such as cabins, barns, RVs, critical-load panels, and small air-conditioning systems.
