    System Diagram

    This diagram shows the 3kW~8kW inverter system: DC power from the battery, PV array, and diesel generator goes through safety fuses and relays, a DC isolation switch, and capacitors. The inverter then converts DC to AC, which is filtered and stabilized, before outputting clean AC power to the grid and loads.
