Description
WK Solar pump inverter controls and adjusts the system operation and converts the DC produced by the PV module into AC to drive the pump, and adjusts the output frequency in real-time according to
the variation of sunlight intensity to realize the maximum power point tracking (MPPT).
Solar pumping systems can be applied to all forms of daily use, water pumping for drinking water supply for remote villages and farms without connection to the water grid, for agricultural use
such as live stock watering, agricultural irrigation, forestry irrigation, pond management, desert
control, and industrial use such as waste water treatment etc.
Solar Pump Inverter Features:
1. Plug and play mode: Only requests correct wiring, motor parameter setting and real VOC setting.
2. Support both DC solar input and AC power input simutaneously.
3. Ambient temperature: -10°C~50°C.
4. Adopt advanced MPPT technology to give full play to the power generation efficiency of the solar cell array.
5. Automatically adjust the motor speed and the water output of the water pump according to the change of sunlightintensity.
6. Maximum power point tracking (MPPT) with fast response speed and stable operation.
7. Digital control for fully automatic operation, data storage and protective functions.
8. can track maximum power of solar panels, and effective to increase the output power of the solar panels9.
Applications:
1. Ground water lowering,2. Irrigation systems
3. Industrial Application4. Drip irrigation& sprinkler
5. Tank/ cistern filling
6. Wildlife refuge
7. Rural water supply for ranches,8. cabins, and cottages
9. Fountains.
