Solar VFD water pump inverter is to convert direct current (battery, accumulator jar) into alternating current (usually 220v or 380V50HZ sine or square wave). It is composed of inverter bridge, control logic and filter circuit.
The photovoltaic pumping inverter is to control and adjust the operation of the photovoltaic pumping system (solar water pump system), convert the direct current from the photovoltaic array into alternating current, drive the pump, and adjust the output frequency in real time according to the change of sunlight intensity to achieve the maximum power point tracking (MPPT).
Railway systems, power plants, power substation systems, etc.
The power inverter can be flexibly set to AC main supply type and DC main supply type:
A) AC main-supply inverter power supply is at the output of the city power when there is city power, and automatically switches to the inverter output when the city power input fails;
B) The DC main-supply inverter power supply is in the inverter output when there is city power, and automatically switches to the city power output when the DC input fails;
The electric power inverter is well-designed, allowing it to cut off the DC when it is turned on, and automatically switch to the mains bypass, without affecting the power supply of the load, and convenient for maintenance and replacement of the battery;
After the battery voltage is high/low and overload alarms, the battery voltage will return to normal and the power supply will automatically resume output. After 50 seconds of eliminating the overload phenomenon, the power supply will automatically resume output. This function is especially suitable for unattended communication base station;
The power inverter supports the AC startup function. If there is a load at the output terminal, the inverter power supply will not be able to turn on;
The power inverter supports the communication function, and uses the monitoring software to understand the working status of the power supply in real time;
The power inverter provides two sets of passive dry nodes, which are used for DC input failure and AC output failure alarm.
