A solar pump controller suitable for 3 phase pumps, which can work with utility supply & also with solar generated DC power.
- Sensor less dry run protection.
- Electronic Motor protection: Short circuit, overload, single phasing, reverse phasing, Stall Protection, under voltage & over voltage.
- Auto start function as per solar intensity.
- Uses MPPT (Maximum Power Point Tracking) to deliver energy at various Solar Energy Levels.
- MPPT (Maximum power point tracker with fast response speed and stable operation.
- Assured running of pump in all weather conditions irrespective of sunlight level.
- Solar or grid power selection.
- Dual Input (Solar + Grid) Preferential Logic.
- GPRS remote control module for distance monitoring, Control, parameter modification.
