Solar Frequency inverter special for solar water pump Adopts the high accuracy MPPT algorithms, tracking the PV array output by the maximum power point, driving the pump motor to meet various pump applications in agriculture, irrigation etc. 1, Supports AC&DC input: DC solar panel input. And If no good sunshine, can use grid AC regular input work the pumps. 2, Dry protection : If no water in the ground, the water pump will stop working automaticly and when the water comes, starts to working automaticly. 3, Automatic working: When the sunshine not good then pumps slow down automatically and when sun become good then go on working. 4, Save cost/directly connect solar panel: Solar panle connects solar inverter directly and to the pump. Also can control the water level in the tank. No enough water in the tank working fast, enough water will stop working automaticly. (how many water you need, you can set the parameters) 5, Speed & frequency control, No need battery: 0-320hz output by Vector control/0-3200hz output by control. 6, RS485 long distance control / Monitor /adjust parameters by computers etc:
