mppt solar charge controller 192v-540v

The solar 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

This kind of solar system is integrated with wind turbine. Solar panel and wind turbine supply power to loads and charge battery together. It is suitable for those area with high-quality wind resources.

The on grid solar power system converts the solar energy into electrical energy, without the storage battery, and directly sends the electrical energy to the grid through the grid-connected inverter. Inverter power: 3kW AC output voltage: three phase Solar panel type: mono or poly

Off-grid or hybrid optional 6KW inverter, Max 3pcs in parallel Grade A battery cells, up to 6000+ cycles 5.5KWh battery, Max 12pcs in parallel Easy to install, combined freely BMS & battery capacity auto-sense WiFi/GPRS remote monitoring (optional)

The solar photovoltaic power system connected to the public grid is called on-grid photovoltaic power generation system. The system structure includes solar panel arrays, DC/DC converters, DC/AC inverters, AC loads, transformers, and other components. Inverter power: 20kW AC output voltage: three phase Solar panel type: mono or poly

The solar power inverter is highly integrated with the digital technology, which can improve the MTBF and reliability of the system, the whole systems are controlled by an independent high-speed DSP chips which can ensure the stability and reliable operation.  Optional power: 40kW 60kW 80kW 100kW 120kW 150kW 200kW Battery voltage: DC192V/DC216V/DC220V/DC240V/DC360V/DC384V Battery type: Gel battery or Lithium-ion battery AC output voltage: three phase 208V or 380V/400V/415V

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
