0.75kW–160kW MPPT Solar Pump Drive for Remote Water Pumping Applications
The Off-Grid Solar Pump Controller is an industrial solar pump drive designed for agricultural irrigation, remote water supply, and off-grid pumping projects where reliable operation and low maintenance are required.
By converting photovoltaic DC power directly into controlled motor output, the system enables battery-free solar pumping solutions while reducing installation complexity and long-term maintenance requirements.
The controller supports a wide range of pump motors, including three-phase AC induction motors and permanent magnet synchronous motors (PMSM), providing a flexible solution for distributors, EPC contractors, and pump system integrators.
Product Highlights
MPPT Solar Energy Optimization
Solar power output changes continuously due to weather conditions and sunlight intensity.
The integrated MPPT control algorithm tracks PV operating conditions in real time and adjusts the operating point to improve solar energy utilization throughout the day.
Key benefits:
Better utilization of available solar power
Stable pump operation under changing irradiation
Improved system efficiency compared with fixed-voltage solar input methods
Battery-Free Direct Solar Pumping
Traditional solar pumping systems using batteries require additional investment and regular replacement.
This controller is designed for direct PV-to-pump operation, helping system owners:
Reduce initial system cost
Eliminate battery maintenance requirements
Improve reliability in remote locations with limited service access
Flexible Motor and Pump Compatibility
One controller platform can support multiple pumping configurations, reducing product selection complexity for distributors and system integrators.
Compatible with:
Three-phase AC induction motors
Permanent magnet synchronous motors (PMSM)
Deep-well submersible pumps
Surface centrifugal pumps
Industrial Protection and Reliable Operation
Solar pumping equipment is commonly installed outdoors and in remote areas where maintenance is difficult.
The controller includes integrated protection functions:
Over-voltage protection
Over-current protection
Over-temperature protection
Short-circuit protection
Fault alarm and automatic restart function
Optional IP65 enclosure versions are available for outdoor wall-mounted installations.
