How to use it:
Connection:
Open the top cover of the controller and connect the wire with terminals follow the diagram on the cover of it
1) Firmly and correctly connect the “+”, “–” poles of the battery to the corresponding ports of the controller (the third and the forth one from the left). When load indicator light flash once and will light after 30 seconds, which means that the connection is correct, and you can continue finishing following connection, otherwise the controller will be damaged
2) Firmly and correctly connect the “+”, “–” poles of the solar panel to the corresponding ports of the controller (the first and the second one from the left). The wrong connection will damage the controller
3) Firmly and correctly connect the “+”, “–” poles of the load to the corresponding ports of the controller (the fifth and the sixth one from the left)
Note: The controller should be connected to the battery first
LED indicator light:
1. The LED indicator is used to indicate the charging status of the battery. When the LED indicator extinguish, which means that the charging is ended
2. The LED indicator light of charging status, the red means that the battery power is low and you had better charge it; and the green means that the battery power reaches to the safe value, you can use it
3. The load indicator lamp light means that it has output and the load can work, if the indicator lamp not light means that it has not output and the load cannot work
Note:
1. Please carefully check and confirm the voltage of the components before connecting, and the voltage of the solar panel is 18V, the voltage of battery is 12V, the rated voltage of load is 12V
2. The rated current of Solar panel and load must be less the than the rated current of controller
What is included:
1 x Digital PWM 20A Solar Charge Controller
1 x User Manual
