3 Phase Solar Pump VFD 380V | Industrial Vector Control for Submersible Pumps | ISO 50001, CE Certified

The PQ580PV 3 Phase Solar Pump VFD is a high-performance variable frequency drive engineered specifically for solar-powered water pumping systems. Designed for 380V three-phase submersible pumps with power ratings from 0.75kW to 4kW, this solar pump inverter converts DC power generated by photovoltaic (PV) panels into stable three-phase AC output.

Equipped with advanced Maximum Power Point Tracking (MPPT) technology achieving over 99% conversion efficiency, the PQ580PV maximizes energy harvest from solar arrays under varying irradiance conditions. Its vector control algorithm delivers precise motor speed regulation, ensuring smooth startup and consistent hydraulic performance for both permanent magnet synchronous motors and asynchronous induction pumps. Whether you need a solar borehole pump inverter for deep-well irrigation or a solar water pump inverter for remote village water supply, the PQ580PV provides a dependable, battery-free solution.

Key Performance Advantages

Industry-Leading MPPT Efficiency

At the core of the PQ580PV solar pump controller is its self-adaptive MPPT algorithm, which continuously tracks the maximum power point of the PV array with up to 99% tracking efficiency. This means more water pumped per kilowatt of installed solar capacity, reducing the number of panels required and lowering overall system cost.

Dual Power Input Flexibility

Comprehensive Protection System

With 25 built-in protection functions, the PQ580PV safeguards both the inverter and the connected pump motor. Key protections include dry-run detection, overvoltage and undervoltage protection, overload protection, over-temperature protection, phase loss and short-circuit protection, ground-to-phase short-circuit protection, and low stop frequency protection. The dry-run protection feature automatically shuts down the pump when water levels drop, preventing motor burnout and extending equipment lifespan.

Intelligent Operation & Remote Monitoring

The solar pumping inverter features fully automatic operation with auto dormancy and wake-up functions, under-voltage restart, and data storage capabilities. A standard RS-485 communication interface enables remote monitoring of real-time parameters — including solar input voltage, output frequency, motor current, and water tank level — from anywhere. Historical data and event logs support proactive maintenance and system optimization.

Plug-and-Play Installation

Designed for ease of deployment, the PQ580PV requires minimal parameter configuration. Simply connect the PV array to the inverter terminals, and the system auto-detects the motor parameters and starts pumping automatically. The intuitive HMI with LED display and tactile keys allows on-site monitoring and quick adjustments. Soft-start functionality prevents water hammer effects, reducing mechanical stress on pipes and pumps.
