WP-4K0-L11 | 4.0kW IP65 Solar Water Pump Inverter - Reliable, Weatherproof and Efficient.

The WP-4K0-L11 is a robust and powerful 4.0kW solar water pump inverter designed for long-term operation in harsh outdoor environments. With a durable IP65 waterproof and dustproof enclosure, it is fully protected against rain, dust and moisture, making it the ideal choice for agricultural irrigation, livestock watering and remote water supply applications.

Designed for single phase (1PH) input and output systems, this inverter offers easy integration into standard water pump setups. Whether used in off-grid solar systems or hybrid energy setups, the WP-4K0-L11 ensures smooth motor operation, energy savings and reliable performance.

The WP-4K0-L11 has a rated output current of 24A, providing enough power to drive 4.0kW pumps efficiently and stably. With intelligent control algorithms, it adjusts output based on real-time system load and solar input, helping to maximise energy use and extend water pump life.

Its built-in soft-start feature minimises water hammer and mechanical stress, making the system more reliable and reducing wear on pumps and pipes. In addition, the inverter is equipped with multiple protection features, including over-current, over-voltage, under-voltage, short-circuit and over-temperature protection, ensuring stable and safe operation under all working conditions.

Thanks to its fanless design or intelligent cooling system (depending on the configuration), the WP-4K0-L11 offers quiet and efficient thermal management, even under high load conditions or in hot climates. It is designed for easy installation and minimal maintenance, saving time and money in the field.

Whether you're managing a rural water project, an agricultural irrigation system or an off-grid water supply, the WP-4K0-L11 delivers the performance, durability and ease-of-use required for reliable day-to-day operation.
