INVERTER BOX is mainly composed of solar panel, energy storage battery and inverter. As an off-grid system which operates independently, and integrates power generation, storage and inver-sion.It can be charged by solar panel, store the solar energy in the battery, and convert it into AC current through the inverter to provide power to the load, which solves the problem of electricity in the areas without power supply electricity is not convenient areas,electricity of cut off areas.Which has a wide range of application scenarios and it is not affected by the State Grid. It is a home-based power supply solution system.
