5KW Solar Pumping Inverter 440VDC

The WP-5K5-L11 is the most powerful single-phase option in the range, delivering 5.5kW of rated power with a maximum output current of 30A. The WP-5K5-L11 solar pumping inverter has been engineered for heavy-duty single-phase applications in situations where three-phase power is not available.

The product's most notable feature is the incorporation of advanced vector control technology, which facilitates precise torque regulation and ensures smooth motor operation.

This technology contributes to a substantial reduction in mechanical wear and noise levels. This is of particular benefit in environments where noise is a significant concern, or when utilising older pump models that are susceptible to voltage fluctuations.

The unit is distinguished by its wide MPPT voltage range, a feature that facilitates the compatibility with a broader spectrum of solar panels when arranged in series. This characteristic is particularly advantageous in reducing both the cost of cabling and the complexity of the installation process. The device has been found to be especially well-suited to large farm irrigation systems, community water supply projects, and industrial cooling water circulation scenarios where single-phase infrastructure is the only viable option.

The construction is robust, ensuring longevity in harsh outdoor conditions. A conformal coating is applied to the PCB in order to resist moisture and dust. The WP-5K5-L11 effectively addresses the challenge of integrating small residential units with large industrial three-phase systems, providing a versatile solution for maximising water output in constrained electrical environments. This ensures reliable operation of critical water infrastructure.
