Power outage

Happy Friday -
I installed a new fridge (Whynter FM45G) on my 1990 Toyota Itasca Spirit and hardwired it to the fuse box. Last night it was working for an hour as I continued to work on the rig until I called it a night. Woke up this morning and went out to go work on her some more and I noticed that all of the power that comes from the new fuse panel is dead. Since solar was added to the rig, there is a separate fuse box than the standard fuse panel located under the couch which takes care of all of the standard electrical this vehicle was originally equipped with. This new fuse box powers an inverter, mppt controller, 2 - 12 volt sockets, and now a fridge. The only thing that works on this new fuse box is the mppt charge controller, everything else is dead. I replaced all of the fuses to see if that would restore any of the power but nothing. Couldn't find any pinched wires that would short anything out. All of the original electrical the vehicle came equipped with is working (lights, stove fan, etc.) What could be the issue here?

    What is battery voltage??


    I am not sure of voltage, I will put a multi meter on it in a bit.

    Specs say it can run on either 120 volts AC or 12 volts DC.
    What are you running it on?
    Home depot specs for refer
    What is source for new panel? Is it fuses?


    Everything on the rig is run off of 12 volt. The fridge is hard wired to fuse panel with a 7.5 amp fuse. Everything was working normal last night, not sure what changed.
  • You said it powers an "inverter"!
    After you read the batteries for voltage, you will get better replies.
    Do you have two sets of batteries, One for chassis and one for coach?
