Main Technique Features
Solar Frequency inverter special for solar water pump [Surface & Submerged ]
Adopts the high accuracyMPPT 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, Accept AC&DC input:
DC solar panel input. And If no good sunshine, can use AC grid to drive pumps;
2, Built-in high precision PV array maximum power point tracking MPPT algorithms;
3, Dry running mode monitoring, Self -protection against over-flow or dry up
If no water in the ground, the water pump will stop working automaticly and when the water comes, starts to working automatically;
4, Automatic working:
When the sunshine is not sufficient, pump slow down automatically, when sunshine is sufficient, the pump will go on working;
5, LED displays the real time situation and the parameter of system;
6, Speed & frequency control, No need battery: 0-400z output by Vector control
7, Based on RS485 real time remote control system
8. Built-in full protection and diagnostic mechanism.
9. Fast installation design, no need extra maintenance
