Solar AC Pump PCU

      A transformer less inverter system, 415 VAC 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 can be possible, better than the conventional methods, it can overcome the problems including poor tracking performance, unstable or even cause water hammer damaging when the irradiation on the array changes rapidly.

Salient features of Solar AC Pump Controller

Due to Designed for power existing AC pumps, Service is easy and available anywhere.
Can be designed for Pumps from 1 HP to 200 HP.
As per IEC/BIS standard (Applied for approval).
Protection functions: Dry running, Tank Over flow, over/low input voltage, over current and over load protection, Reverse Polarity etc.
High quality, low cost, compact design and high reliability.
High Efficiency: 96%-98%.
Very Low Harmonic Content.
Dual mode operation: can be operating on electric power at night and solar power at day time.
Inverse exponential speed variation at the time of lack of solar radiation.
Can be integrated with existing system.
Possibilities for monitoring from remote Area.
Can be monitored large number of solar water pumping systems centrally.
The pump works automatically as the sun rises and falls
