mppt solar charge controller 192v-540v

The off grid solar inverter can be put outside and work without battery. Both solar panel and grid are connected to the inverter, solar is priority, grid will be backup. It is very suitable for such situation: loads work at daytime, with grid connection. Electricity bill can be saved a lot. The inverter power range can be 5kw to 500kw.

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

The 20kW off grid solar system is suitable for area without grid or grid is unstable. It can be compatible with generator to saving electricity bill and increase the power quality. Inverter power: 4pcs 5kw in parallel AC output voltage: AC220V/230V/240V or AC380V/400V/415V 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

1. Intelligent management system and multiple working modes, meeting different customer needs 2. Allowing you to set the priority of grid connection, battery type and other inverter information on the LCD screen. 3. Dual MPPT, high current input, compatible with large solar cell module of 210mm, flexible configuration, 4. All-in-one design, providing backup power and peak-shaving function. 5. With a battery safety management system, supporting the remote upgrade of BMS system.

The 50kw off grid solar system is designed for farm or hotel use. It can compatible with grid or generator. Solar is priority, gid and generator will be on standby mode. Inverter power: 50kW power frequency inverter AC output voltage: Three phase 208V or 380V Battery voltage: DC220V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly

The solar Multi-split hybrid AC/DC air conditioner can work without battery, it works with unstable solar panel DC power at day time. At night or rainy days it automatically get grid AC power. It's  mainly used for school classroom, hospital, restaurant, shops, office… With APP monitor and control function through WIFI
