7. Trouble Shooting Guide
The HSR12VXX series controllers are of good quality; if you have any trouble or problem, please check the
units as follows or contact the supplier:
Problem
The charge indicator is flashing
Details
The buzzer will warn when reverse connected.
When you connect the solar panel, if the polarity is not properly respected, its
protection system will be activated, not allowing the charge controller to work.
Once the polarity connections are properly restored, the unit will start working
properly again.
When the solar controller is on, but the battery is not connected, the solar controller
will limit the voltage to prevent the load from getting damaged.
Solution
The battery has been wrongly connected;
restore the right connection.
