These solid-state controllers will protect the 9300 pump from over-voltage and over-current conditions and will provide current boosting in low sunlight conditions, providing both protection and maximum water delivery.
SHURflo 9300 Pump Controllers optimize your solar water pumping system by translating the current and voltage available from your photovoltaic panels into a combination better matched to the pump requirements. With an optional Float Switch installed, the controller will automatically stop pumping when the storage reservoir is full. One of these controllers is required for PV array-direct pumping systems with
the SHURflo 9300 submersible pump.
The SHURflo 902-100 controller is not waterproof, so it must be mounted in a dry location or an appropriate weather-tight enclosure. For use with a 24 VDC nominal PV array. Maximum input voltage is 45 VDC, and max output is 28 VDC and 5 A.
The SHURflo 902-200 controller has all the features of the 902-100 and more. This controller is switch selectable for 12 or 24 VDC operation and includes a manual on/off switch for easy pump maintenance.
The 902-200 controller comes complete with three high / low water level sensors and sensor wire. Water sensors hang in the well and are used to prevent dry-running in low yield wells. Maximum input voltage is 45 VDC, and max output is 28 VDC and 7 A. Use a single 36-cell 12 VDC module (reduced water delivery) or two in series for 24 VDC nominal operation. The 902-200 includes a weatherproof enclosure suitable for outdoor mounting.
A single common 60-cell module can also be used with either controller, and will produce the 4A max current that the pump draws with only about 50% of full sunlight. This will increase the amount of water delivered per day by increasing water output early and late in the day or in cloudy weather.
