The IDEEI QB-Hi series is a single-phase off-grid solar inverter (4kW-11kW, 220/240VAC) powered by solar panels only — no battery, no grid connection — for daytime use. Up to 99% efficiency, 160-390VDC MPPT and a single IGBT power stage drive daytime loads directly, eliminating battery cost and maintenance.
The QB-Hi series is an advanced off-grid solar inverter lineup covering 4kW, 5.5kW, 7kW, and 11kW models, designed for direct solar-to-appliance power. It runs on solar panel power only — no battery, no grid connection — for daytime use, built around a proven single IGBT power stage. With a max conversion efficiency of 99%, the series is the ideal solution for powering essential daytime loads in homes, farms, remote cabins, and monitoring stations directly from solar energy.
