Product Description
ERSAN V70 Series Solar VFD, the excellent MPPT function enables the efficiency to reach 99.9%. It can track the light automatically throughout the day and can drive a variety of different types of pumps (for example: permanent magnet synchronous, asynchronous motors, etc.), And it contains water level control parameter group especially. High performance with multiple protection functions. Direct air ducts up and down, DC fans dissipate heat. Standard 485 communication design, that is convenient for networking to monitor the inverter. It support PID control and AC & DC dual power supply. Our solar frequency drives are suitable for farmland irrigation, residential water, landscape fountains, swimming pool water supply, desert management.
