It is difficult to cover the traditional power grid in remote areas, but the local solar resources or wind resources are usually abundant. Sunpack can provide high-power (above MW level) independent micro-grid solution, which can combine various input power sources, improve the reliability of power supply, so that local residents can realize an independent off grid system.
