Boost your DC solar pumps performance by up to 30%. Controller optimizes your solar water pumping system by translating the current and voltage available from your photovoltaic panels, into a combination that is better matched to that needed by the pump.

With the optional float switch installed, the controller will automatically stop pumping when the reservoir is full.

The versatile 902-200 has all the features of the 902-100 and more. This controller includes a manual on/off switch for easy pump maintenance. The controller comes with high / low water level sensors so the pump will not run when the well water is too low. Weather proof enclosure.
