Solar Controller showing no input

[Cassidyuk]

Hi
I am off to France tomorrow and noticed that the input LED is showing no display on the solar controller
Its measuring 21v on the input terminals and the output display is showing 13.7v to the battery
Do you think it just could be the LED has packed up or maybe the controller has packed up ?

As you have an output above battery voltage then yes I would assume it’s working with a failed led

That’s sitting on float at that voltage. Will tail off when the sun gets low.
See what it shows in the morning if the volts are around 14v it’s still working and on bulk charge assuming it’s fairly bright. Then it will return to float.

Obviously you haven't got time to sort a problem before leaving if there is one.
So have a look when you are settled somewhere.

When the sun is out in the put a load on the battery (switch on lights & TV etc.)
The battery voltage should gradually ramp up to 14.4v. Once you see the voltage rising you can turn off the loads. When the voltage gets to 14.4v I don't honk your controller has an absorbtion phase so it should drop to around 13.8v which is the float charge
