CONNECTING THE CONTROLLER
The Waterboy MPPT Solar Pump Controller must be mounted close to the solar array and pump, in a
secure and protected position. Mount the controller vertically using the mounting plate supplied, in a
ventilated area out of direct sunlight. This is often half way up the array post under the panels. The
controller should be placed at a good working height, shaded by the panels and protected from
contact by livestock, wild animals or children. Ensure that safety devices such as a DC isolator is
switched off, or the solar panels are unplugged prior to opening and working on the controller. Make
sure that all connections on the terminals are tight, with no loose wires before switching on.
Wiring
(See electrical diagrams overleaf)
1. Set the switch in the controller to the OFF position. This is the middle position on switches marked
SOLAR / BAT.
2. Insert the pump power cable through the largest gland in the bottom of the controller box, being
careful not to damage any components on the board.
3. Connect the 3 wires to terminals as indicated (1, 2, 3).
4. The low water circuit uses the normally closed (NC) terminals, COM1 and WH. If no sensor is being
used connect a link/jumper wire between terminals COM1 and WH.
5. Insert the low water cable through the smaller gland in the bottom of the controller box, being
careful not to damage any components on the board.
6. Connect the two wires to the terminals COM1 and WH.
7. The tank full circuit uses the normally open (NO) terminals, COM2 and TH. If no tank full/ pressure
switch is used, leave open.
8. Insert the tank full/pressure switch cable through the smaller gland in the bottom of the controller
box, being careful not to damage any components on the board.
9. Connect the two wires to the terminals COM2 and TH.
10. Connect the controller leads to the solar leads or isolator (if supplied).
11. If the solar array has a circuit breaker/isolator make sure that it is OFF before attempting to
connect the array to the controller. Connect the leads from the solar panels to the top of the
isolator, connect the leads from the controller to the bottom of the isolator.
12. Turn ON the solar array circuit breaker/isolator if one is being used with the system.
13.
Ensure the pump is submerged before proceeding!
14. Switch the controller to ON (SOLAR); all indicator lights will turn on briefly and then go off except
for the “SYS” (System) light which should be green. After a few seconds the green “PUMP” light
will turn on and if all is connected correctly the pump will start.
15. The green MPPT light will flash on and off during pump operation.
16. Shutdown: always turn off the controller before switching off the main isolator switch.
