Solar Pump Inverter (Solar pump controller) : A
transformer-less Inverter system, with **5 Vac, *-phase output
voltage and V/F control to manage pump starting condition (soft
start). The equipment is micro controller 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.
