Be Energy Independent – Qoltec 11000W Off-Grid Hybrid Inverter

How Does It Work in Off-Grid Mode?

Take full control of your energy with Qoltec’s off-grid hybrid inverter — the essential link between solar panels, energy storage, and your electrical appliances. This intelligent device converts solar DC power to AC, powers your devices, and stores excess energy in batteries for use during low sunlight periods or at night.

• Works with LiFePO4, AGM, GEL, and deep cycle batteries

• Automatically switches to battery power when needed

• Stores energy efficiently to reduce dependence on the power grid
