Solar Doesn't Seem to Work

I'm new to having a 32RLS 5th wheel. Just picked it up from the storage and turned on both the battery and solar. It doesn't seem that the solar is charging the battery. Any suggestions on what I need to do would be great.

Is it sunny? LOL
Seriously though —
If you connect shore power will the converter charge the battery?
If you connect to your tow vehicle will it trickle charge your battery?
What type of battery? Was it dead when it came out of storage? FLA or AGM may be a boat anchor now. LFP might need to see a charger for a few seconds to turn it back on. In the future the battery disconnect is insufficient for long term storage, you need to disconnect the NEG battery cable.
I don't know which MPPT you have but have you tried the owner's manual for it?
Is there voltage being supplied to it by the panels?
Is it outputting anything?
Many people will have ideas to help but we'd need to know more about your equipment.

As George stated, additional details will be needed.
What type of Solar Controller? Does it have a display? Pictures? Battery Type? Multi meter Readings?

Appear you have already checked O.C.’s suggestion and report that the solar master switch is on.

My 2024 32 RLS had a blown fuse on the roof. I noticed my solar was not working either and I was looking at the mppt controller and there was a half moon on it and it never changed throughout the day. I wrote in the forum about 6 months ago or more regarding this problem and got lots of help from everybody. I went up top onto the roof and found that the fuse that was on the roof from the solar panel to the cable that goes into the roof of the trailer was blown. I purchased a new fuse and dropped it in. connected it and and bingo my solar up and running. not sure if this is the type of problem you're having, but it's worth a try to check it
