5.  Summarize 

CPT series solar charge controller is a specially for the sunshine of the good development of a region and a separate simplified controller Suitable for 12V automatic control system, and some models with USB5V / DC12V output, to facilitate the use of smart devices and lighting.

Connection ( As indicated in diagram ):

Open the top cover of controller and connect the wire with terminals follow the diagram on the top cover of it.

1. Connection the “+”, “-” Poles of the battery to the corresponding ports of controller ( the third and the fourth one from left ).

* The subsequent operation can be processed only if the load indicator ( mark: load ) flickers once and starts lighting after 30 seconds.

2. Connect the “+” “-” poles of the solar panel to the corresponding ports of controller ( the first and the second one from left).

3.  Connect the “+” “-” poles of the load to the corresponding ports of connector ( the first and the sixth one from left ).
