12V System80A MPPT
12V Hybrid Solar System
ECG 1.8kW
A high-power 1.8kW 12V unit for a small home or workshop on an existing 12V battery bank — simultaneously runs lights, fans, a TV, an inverter fridge, and a washing machine. The 80A MPPT accepts up to 2,000W of solar panels at 450V Voc, delivering far more daily solar harvest than typical 12V inverters.
