Solar issues

[Sirrell85]

Afternoon, any advice appreciated. Never really paid any attention to the victron app. I'm away in the van and have had the dometic fridge running for 24-36 hours, charged the phones and used minimal lighting. I think the fridge is just using the leisure battery, which may not be getting topped up with the solar. Arrhghhh. Thank you

This looks like a fouled solar panel to me..

You are getting a small bit of power in the morning and then as soon as the solar panel heats up it cuts out....

You are showing zero volts solar panel voltage on this screenshot.... And the other screenshot shows a small amount of power in the morning before the panel gets warm.

Have you got a few pictures of the solar panel on the roof?

Looks like it may be time for a new replacement solar panel

Not the best pics. Thanks for the info so far mate

Forget the solar and just add another battery

I'm assuming it's a really huge big capacity lithium battery that's still pretty full if it's above 13v?

Any bumps or tiny burns on the busbar lines?

How old is the panel.

Easiest test is to connect in a temporary portable solar panel to test the rest of the kit.

Ie a portable fold out panel?

Only 2 years old. I'll have a proper look at it when I get back home tomorrow

Very odd then, your panel has been up to 25v so it must be working ...

I wonder if its what @Dellmassive said about the panel heating up, is it possible for the weather to be too hot for a flexi panel to work?

Maybe? Assume you have a charger for when the engine's running as well?

Yeah, new to all this stuff so takes some getting use to

And did you drive it during the 24 to 36 hours of running the fridge?
