Solar pump inverter (Solar pump controller)
A transformer-less Inverter system, with 415 Vac, 3-phase output voltage and V/F control to manage pump starting condition (soft start). The equipment is microcontroller based and operated with software for digital control of inverter parameters, fault finding-diagnostics and digital I/O signalling.
Inbuilt MPPT Control
With the function MPPT (Maximum Power Point Tracking), it regulates the output frequency according to irrigation in real time to achieve the maximum power. Adopting the proposal dynamic VI maximum power point tracking (MPPT) control method, fast response and stable operation, better than the conventional methods, which may lead to the problems including poor tracking performance, unstable or even cause water hammer damaging when the irradiation on the array changes rapidly.
