The WP-2K2-H33 is designed for users with access to three-phase power who require a compact, energy-efficient pumping solution. This model is ideally suited for small commercial greenhouses or community gardens, leveraging the inherent balance of three-phase electricity to provide smoother torque to the pump motor compared to single-phase equivalents. One of its key benefits is the ultra-low start-up voltage requirement. This feature enables the system to initiate pumping operations earlier in the morning and extend them later into the evening, thereby optimising the daily water yield from a given solar array size. This is particularly beneficial in winter months or high-latitude locations where sunlight hours are limited. Additionally, the inverter includes a programmable timer function that allows users to schedule operations based on time-of-use electricity rates or specific watering cycles. For instance, it can be set to prioritise solar power during peak sun hours and supplement with grid power only during off-peak times, drastically reducing operational costs. The enclosure is treated with a conformal coating on the PCBs, offering an extra layer of defence against humidity and corrosive gases often found in agricultural environments, such as those used for storing fertiliser. The WP-2K2-H33 combines precise timing controls with robust hardware protection, ensuring the profitable and reliable running of small-scale commercial operations. It minimises waste and maximises crop health through consistent hydration schedules.
