Yay! I'm finally back. With the forum change, the login via Google got blowed up. It just got fixed a few minutes ago. Lots of updates. We're close, wife has been working on all business documents we need, which as been a real PITA. The last thing we needed to finish with the trailer is getting the fridge running. We had tested the compressor when we got it home, but it has since seized up, which meant buying a new compressor and installing it ourselves.
That went ok, had a buddy of mine come over that knows how to braze copper pipe. But while fillling it, we noticed a strange thing happening with the pressure, and the next day we were completely out of coolant again. Then I realized, we never pulled the rubber plug on the other service port and capped it, because we got distracted while working with the compressor. He was away for a week, so I bought myself a MAP Gas torch, cut a piece of copper pipe, sealed one and and brazed it myself.
We got it running that it was cooling, but we found we had a freezing issue.
Which we solved with some insulation
I also added a pair of 12v IP67 rated fans inside the fridge to give some air movement across the evaporator, the next morning I woke up to this:
We had finally broken the 41F barrier. But then another problem arose, the inverter doesn't have enough umph to run the compressor. There's a huge inrush current flow to start the compressor. I tried to mitigate that buy delaying the condensor fan starting for 60 seconds, but that wasn't enough. The choices are buy an expensive RV soft start and hope it works, or get a bigger inverter. We pick up a 3500/7000W inverter tomorrow. The compressor will start on our 4300W generator without problem so I think the inrush is just a little more than 4000W, and our 2000/4000W inverter isn't enough.
In between working on the fridge and running produce across state lines, I installed this huge solar panel on the top of my truck.
With it and the other panel on the trailer I can now generate up to 25.5A, while the trailer with everything on is drawing about 18A. On a good sunny day, we can run completely off of solar power, making us the quietest truck out there, everyone else is running large generators. We now have a pair of marine batteries on board, and with the truck connected via the trailer plug, there's 3 in parallel.
I did have the trailer at a refrigeration service place for them to look over it and they gave us several things that we should do, which one was add more ventilation to the cabinet. I finished that yesterday.
I also mounted a 10" 12vdc fan on the louvered door to the cabinet to draw air out, it'll switch on with the other condenser fan.
With the addition of the big ass solar panel on the roof, that meant a larger charge controller in the trailer. There's a Renogy 30A in there now, and the 20A is now mounted in my truck. I plan to take the other inverter and mounted it in there too, with another marine battery so if we're out camping, or anything else, we have power directly in the truck.
We're looking at a November 10/11th opening, 1 year from the day I killed a horse and this all got rolling.
