mppt solar charge controller 192v-540v

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 5kw solar inverter is integrated with MPPT solar charge controller inside. It can also connect to grid to take grid as backup when battery is over discharged. The output voltage is 220V, maximum 6pcs in parallel. 3pcs in parallel can get three phase 380v output. All of parameter such as working mode, charging current, over discharge voltage can be set as you wish.

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 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

The charger is an AC to DC charging module. It has the advantages of wide constant power voltage range, high efficiency, high power factor, high power density, minimal electromagnetic radiation and interference, and high reliability to meet the fast charging needs of various batteries. ,Energy saving and environmental protection.

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.
