4” Solar Go-kits

The 4″ WPS® Solar ECO Pack is a complete solution for solar pump systems with 4″ borehole pumps. The system consists of a WPS® 0.37 kW 3x230V AC motor and a 4″ WPS® stainless steel borehole pump.

A special WPS® Solar controller was developed for this motor power, equipped with a voltage boost module. This makes it possible to reduce the number of solar panels required from four to two 270 Wp units. This significantly increases the overall efficiency of the system. The system delivers a flow rate of 1.5 m³/h to 8 m³/h, with a maximum head of 38 metres.

This solution is particularly suitable for:
– Agriculture and irrigation
– Tank applications
– Water supply for livestock
– Domestic applications
– Water supply for small communities
