HY series solar inverter with built-in mppt charge contronller, 750W hybrid inverter,

1. Introduction:                                          

2. MRE hybrid inverter system is a battery charge and discharge control, photovoltaic and electricity switching control and inverter control multifunctional integrated system,composed of PV array, power grid , battery, off-grid hybrid inverter and  AC load, photovoltaic array absorbs solar radiation, convert it to electricity to provide power,

off-grid hybrid inverter can control both battery and mains intelligent charging, while the inverse DC battery power into AC power for the entire system for the load.

System uses a PV priority mode, according to battery capacity , photovoltaic charging current and the load, the controller automatically controls the charger from the power grid.

So it can maximum use of solar energy while ensure continuous demand for electricity.

It was resolved without public grid or grid electricity in underdeveloped regions of the daily program of choice.

Working principle diagram:

2,the principle of the internal structure of the product:

Off-grid hybrid inverter composed of PV MPPT charging controller , power grid charging board ,inverter board and whole control system , system uses a common DC bus mode,

the battery, the output of the PV inverter and battery charger and grid intersection into a DC charger input bus, also the battery charging DC bus current path, charging the grid photovoltaic charging priority;

3,Features:

1) intelligent battery management system , it can extends battery life.

2) LCD display , it can show :Solar charging current, the solar array voltage, solar power, battery voltage, the inverter output voltage, output frequency, output power etc.

3) solar work priorities. Always take precedence over the use of solar energy, maximize the use of solar energy.

4) When the solar and mains charging current is insufficient to supply the load, the inverter automatically switches to mains bypass. Ensure un-interruptible power to run load.

5) when the solar power supply returns to normal, the inverter will automatically switched to the solar power.

6) Strong ability of resisting concussion, can load all kinds of electric apparatus and industry equipments, such as air conditioner, refrigerator, television, fan, washer, fill water electric motor, tortile gate, etc..

7) high transfer efficiency, up to 95% (different materials transformer has different transfer efficiency)

8) Protection function: output short circuit, overload, low voltage, etc.
