Wiring Instructions
1. Wire preparation: It is recommended to use multi-strand insulated copper wire. Firstly, make sure the length of the cord, secondly, ensure the installation location in the circumstances, thirdly, try to minimize the connection length to reduce power consumption. According to not more than 4A/mm² in accordance with the current density of selected cross-sectional area of copper wire, the controller side of the first strip 5mm of insulation should be shucked off.
2.Firstly, connect battery termination to the controller, and then connect to the other ends of the battery. Pay attention to +, -, do not be reverse. If the connection is correct, BS should be lighted, according to buttons to check. Otherwise, need to check the connection. In case of reverse, will not burn any part of the insurance and damage any part of controller, fuse only as the end protection of a controller itself to protect the amount of internal short circuit damage.
3. Photovoltaic cells’ wires connected, connect solar panels termination to the controller, and then the other ends connected to solar panels. Pay attention to +, -, do not be reverse. If it is a sunny day,charging indicator light should be bright. Otherwise, there is need to check the connection.
4. Load connected: connect the wire of load to the controller output, pay attention to +, -, do not be reverse. Otherwise, it would burn appliances out.
5.Connecting photovoltaic cells and the load wires as followings: remain a curvature along the wire to prevent the controller from rain water.
