The installation and precautions of the solar controller
1. Unpack and fix it securely in a suitable location (please avoid direct sunlight and moisture).
2. Connect the battery leads first (in order to make the automatic identification function not in error), and wait for the controller to complete the identification process (the level indicator indicates the battery power) and then connect the solar panel leads, and finally the load is turned off. Connect the load line in case.
3, in order to use safely, do not make excessive load or increase the solar panel too large; replace the solar battery with a power source such as a power supply to charge the battery.
4. When charging, remove the solar panel and the charging current should not be too large.
5. Pay attention to the positive and negative of the battery.
