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 |
