We are at a dry camp music thing. The Dulcimer Funfest in NoWhere MI (Evart). It isn't rally in the middle of nowhere, that's about four miles up the road.
We have electric only refrigeration and the most efficient dorm size (this is a 23 - remember) uses about half again more power than our Nocold did when it worked. Now I have a good running APU (Generator) and a PD9245 converter And a new this year Bogart Trimetric 2025 Battery monitior. (Trimetric is already highly recommended and they have a new number that does more.)
That is the big problem. Now that I have a very good picture of what all is happening, I don't like it at all.
From a battery at 57%, the best rate I could get was 25A. Trimetric said that and I believe it and I also believe (because I checked with a Fluke that the battery terminal was only 13.6V. So I checked at the PD's terminals, 14.4 just like advertised......
So, the little POS #10AWG that is OE is less than effective. My house bank is in the starboard (right) bow (front). I find it believable that the #10 could burn off 0.8V, but I don't like it. That means what should have been a 2 hour charge run is being more like 3 hours.
Has anybody replaced or parallel this cable with good results?
I am planning to get about 25' of #6 THHN (maybe #4)and then try to figure out how to get it there.
Yes, I will also harden up all the other places as well to make the whole charging circuit more solid. I am a little concerned about the frame as a the return path.
