Why is not my solar panel charging for last to days? When I disconnect the panel I have over 22V from it and when I connecting it back to the regulator the voltage drops to a little bit over 1V measuring whit a multimeter. The app is telling me about the same voltage that's in the batteries. Last two days it's been a lot of sunshine so that can't be the problem.
One would suspect a high resistance joint/terminal/fuse somewhere.

Perhaps reverse polarity connection, or faulty solar panel?
Hi,
if you did not change anything on your installation and see these symptoms, there is a chance that the unit is broken unfortunately. It would be best to talk to your dealer.
