WP-4K0-H33 | 4.0kW Three Phase Solar Water Pump Inverter - High Voltage, High Efficiency and Outdoor Ready

The WP-4K0-H33 is a robust and intelligent 4.0kW solar water pump inverter designed for three-phase water pumping systems in demanding environments. Built for efficiency and durability, this inverter is the ideal choice for agricultural irrigation, rural water supply and solar-powered pumping stations.

With a wide AC input voltage range of 380V (-15%) to 440V (+10%), the WP-4K0-H33 is compatible with a variety of grid and generator power sources, offering flexible installation and reliable performance in both grid and hybrid applications. It is also designed to work seamlessly in fully off-grid solar systems.

Optimised for solar efficiency, the recommended MPPT voltage is 550V, ensuring the inverter operates at its highest efficiency point. Integrated Maximum Power Point Tracking (MPPT) technology allows the inverter to continuously track the solar input in real time and adjust the output to harvest the maximum energy from the solar array. This results in optimal system performance even under variable solar conditions.

The WP-4K0-H33 supports 3-phase input and output, ensuring stable and smooth operation for industrial pumps and motors. This makes it particularly suitable for medium to large irrigation systems or water supply projects that require consistent water delivery.

Housed in a rugged IP65 waterproof and dustproof enclosure, the WP-4K0-H33 is designed to withstand harsh outdoor conditions such as heat, humidity, rain and dust. It can be installed in remote agricultural fields, deserts or mountainous areas without the need for an additional protective cabinet.

The inverter also incorporates a full range of safety features such as over-voltage, under-voltage, overload, short-circuit and over-temperature protection. Its intelligent soft-start function reduces water hammer and mechanical wear, extending service life.
