Connecting AC to Pressure Pump and GLS systems

You can connect AC into your pressure pump controller to help supplement battery charging when there is not enough solar. Depending on the model of pump that you have, you can either connect 110VAC or 220VAC, this can also be found out by looking on the sticker on the left hand side of the controller. Either you can request a plug from us or you will need to source the plug locally, it's a standard wall plug male pigtail for 110VAC or an NEMA 14-30 male plug pigtail for 220VAC. For the 110VAC connection, you will wire one hot, one neutral, and one ground into the controller like the diagram below.

​
For the 220VAC, you'll wire the 2 hots into the corresponding connections, wire out the neutral and one ground like the diagram below. For both grounds, the ground wire will be sharing the same terminal as the pump's ground.
