Installation Instructions
1. Strongly and securely install the controller;
2. The preparation of the conducting wire:calculate the length of the wire ,and then figure out the installation place,make sure the length of the wire is reasonable to decrease the loss of the electricity;
3. Connect the battery first,pay attention to the anode and the cathode to avoid the inverse connection.the indicator light of the battery will work if the connection is correct,otherwise,it will not ,but the component of the controller will not be damaged;
4. Connect the wire of the solar panel, pay attention to the anode and the cathode to avoid the inverse connection.if the connection is correct,the indicator light of “CHARGE”will be on or flash 10 seconds later after laying outside under the sun,otherwise,please check the connection.make sure the solar energy panel is laid outdoors under the sunshine;
5. Connect the load at the end, pay attention to the anode and the cathode to avoid the inverse connection .if inverse connection ,the led lamp may be damaged;
6. The controller’s maximum wire diameter range: 20-2AWG(0.5mm2-33.6mm2).
