WP-7K5-H33 | 7.5kW Three-Phase Solar Water Pump Inverter – High Efficiency, Strong Power, and Reliable Performance.

The WP-7K5-H33 is a high-performance 7.5kW solar water pump inverter, purpose-built for medium to large-scale water pumping systems. Designed with cutting-edge power electronics and intelligent control, it offers robust and reliable operation for agricultural irrigation, livestock watering, and rural water supply-especially in areas where grid access is limited or unreliable.

This model supports three-phase (3PH) input and output, making it ideal for driving powerful AC water pumps that demand higher stability and efficiency. With a rated output current of 18.5A, the WP-7K5-H33 delivers the strength and consistency needed to support high-capacity pumping tasks over long hours of operation.

One of its standout features is its Maximum Power Point Tracking (MPPT) efficiency of 99%, ensuring optimal solar energy utilization. The MPPT algorithm continuously tracks and adjusts to the best power point from the connected photovoltaic array, even under rapidly changing environmental conditions like shading, temperature shifts, or partial cloud cover. This ensures maximum water output throughout the day with minimal energy waste.

The recommended MPPT voltage of 550V makes it well-suited for mid- to high-voltage PV arrays, allowing for efficient wiring design, reduced cable losses, and easier compatibility with a wide range of solar panel configurations. This design flexibility supports both compact and large installations.

The WP-7K5-H33 is built to withstand tough environmental conditions. With an optional IP65-rated enclosure, it is fully protected from dust, water spray, and outdoor weather, making it perfect for field deployment without requiring a control room or additional protective housing. Whether installed in a remote farm or near a wellhead, this inverter ensures dependable performance.

It also features advanced motor control, including soft start and variable frequency output, which helps extend pump life, minimize hydraulic shock, and improve operational efficiency. Users can fine-tune motor speed and power delivery based on water demand and solar availability, improving overall system productivity and water resource management.

To ensure system safety and durability, the WP-7K5-H33 includes comprehensive protection features: over-voltage, under-voltage, over-current, short-circuit, and over-temperature protection. These safeguards help prevent equipment failure and provide peace of mind in demanding real-world applications.

The inverter offers a user-friendly interface for local configuration, plus optional communication ports (RS485/CAN) for remote monitoring and integration into smart solar or irrigation management systems.
