Note:
1.The function of the controller is to protect the voltage overshoot and discharge.
2.When the battery voltage is too low, the controller to stop output; after the solar panels charging, the battery will return to 12.6 v. It is a natural to output.
3.12.6 v is to restore the discharge voltage.
4.When the solar panels to recharge battery float charging voltage can be achieved. It will stop charging. This is called overshoot protection.
5. After the battery discharge, the battery outside will flash, this is to remind the user, the configuration is not reasonable, it need to take battery connection.
6.The controller normal voltage of 10.8 v to 13.7v. This two voltage fluctuation, you can be set manually

If you got trouble in using please try to adjust the Float Voltage to 13.7V:

Firstly, you need to long press the "MCU control" button about 3-4 s, and then there will be a management interface on the screen.
Secondly, you have to press the "Add" button under the screen until the voltage reaches 13.7 volts.
Lastly, you need to re-press the "MCU control" button again, when the display doesn't blink anymore it saves controller recording the data.

Package Includes:
1 x Solar Charge Controller
1 x User Manual
