Can I program or do I have to take it to dealer? Thanks so much for your help.

I agree with Jim, programming could be an issue. If your batteries are dead, the controller should not be in float mode.
Starting to suspect a blown solar fuse or mis landed wires within your system.

Te dealership said the "battery is concidered fully charged anf the controller is maintaining the battery charge. Not the case obviously.

Understand your upset, I get it is frustrating on your first trip.
To check the programming you will have a small rotatable switch on the bottom side of your controller.
It is just a matter of pointing the arrow on the switch per the correct number based on the manuals recommended settings.
It really feels like this is more then a setting to me…….. just a guess of course.

Wow, it would appear that the dealership needs to send its tech’s to some training classes. How in the world can they say that if your batteries are dead. Sorry you are going through this delima!

I just zoomed in on your picture, you need to check those battery terminal connections on your controller for proper polarity with a meter.( the ones OC called out with arrows)
It sure looks like the black wire is connected to the positive connection and the red is connected to the negative.
A meter will tell you the truth when hooked to those terminals.
Just an observation.
Please get us a better shot of the wires going into this controller. As Bryan said...they might be backward.

Side note, is your genset an nps6000? If so, it DOES have an emergency pull start behind the air filter housing. I had to pull start one time boondocking and let the battery completely die. At least you could get some juice into the system to continue testing.
Also, fingers crossed for you that the fridge didn't burn up a control board with the dead battery. (I've had two bite the dust). Once you get the generator fired up, check the fridge to make sure it powers on, if not, start that claim as well...

I do not see a pull start on this generator anywhere.
The Victron inverter isn't really installed upside down...is it?
Still need better picture of your MPPT controller...show us the wires please.

Linking the manual for your generator as well for your future use. I didn't get one with my unit from Alliance either.

If you ever have any issues with the generator, call NPS directly they are very helpful.

Well, the PV value proves you have voltage coming from the panels.
We still need a good picture of your controller wiring connections. The fact that the voltage is jumping from 3v to 9v
supports a problem for sure.
Like I indicated earlier your battery wires could be reversed based on your original picture.
Hope your making progress getting to the bottom of this issue.
