Common system errors and solutions:

Phenomenon

Causes and solutions

When there is sun rays irradiating at solar panels LED indicator (1) don't work;

Check the if connection of solar panels and this controller is correct like if there is reverse connection of anode and cathode even if there is disconnect of terminals;

Solar panel indicator (1) flashes fast;

System is in the stage of over voltage; there is disconnection between battery and solar panels even final loads , check if the charge circle is in right connection.

Load indicator (3) working normally but there is no output;

Check if the connection of loads and controller is in the right method

Battery indicator turns red and there is no output-loads don't work;

Battery is in the stage of over charge , charge the battery again to reuse
