The 10kW solar off grid power plant is composed of solar panels, batteries, inverters and other accessories. This system can supply power to home loads independently, also it can be connected to grid or generator to take them as backup when battery is over discharged. Inverter power: 2pcs 5kw in parallel AC output voltage: AC110V/120V or AC220V/230V/240V Battery voltage: DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatible with grid and generator Monitor: WIFI or GPRS

Such hybrid solar system can work as both solar on grid system and solar off grid system. It can utilize electricity price difference, charge battery at low price and discharge at high price to maximize system profit, compensate local transformer limit. It can  provide back-up power supply for unstable grid, during grid failure, seamless switches to off-grid mode within 20ms to realize uninterruptable supply

Characters Transformerless with three level topology Max efficiency up to 98.6% Dual MPPT inputs accommodating wide voltage range Compact structure design Complete protection function such as anti-islanding, short circuit, overload Easy installation and free maintenance WiFi or GPRS (optional) communication Component brands Specification Model No ST17KTL ST20KTL ST25KTL DC side/Input parameters Max.
