Specifications:

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
