A transformer-less Inverter system, with 110/160/230/320/415Vac, 3-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 signaling.
With the Inbuilt MPPT (Maximum Power Point Tracking) function, it regulates the output frequency according to irradiation in real time to achieve the maximum power. Adopting the proposed 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.
