PD4645 ugrade, from 25 amp Magnatec?
I currently have a Magnatec 6300 series (25 amp) converter in my camper. One battery, the batter is at the rear left side of a 9.5 foot camper. Quite a bit of wire to get back to the converter. I ...

8 gauge is fused at 40 amps, 10 gauge max fuse size should be 30 amps.
That said, a #12 wire used in a oven can carry 30 amps with the proper insulation so that the wire heating to 200F will not be damaged. But normally #12 wire is good for 20 amps in a home and will last with average wire insulation 50+ years of the home.
I would not think that your camper came with a 25 amp cheap charger and upgraded wiring. So it might have 12 or 10 gauge wire. 10 gauge will work with your 45 amp converter because most of the time 30 amps will not be going into the battery. Chances are when you start your generator, it might put 30 amps into the battery until the voltage goes over 13.4 volts, then charge rate slows. Even my 70 amp charger with 4,000 watt generator and 4 golf cart batteries will not put out more than 45 amps for more than a few minutes. Once the battery reaches 13.2 volts, charge rate slows.
The 25 amp converter might have used about 2.5-3 amps at 120 volts, and run fine on a small generator. The 45 amp can use 5 amps 120 VAC, or about 600 watts. If the generator is not up to the task, you will have a problem.
A $229 solar panel can solve all of these problems.
SunElec.com sells a 140 watt solar panel with a aluminum frame, and about $229 a few weeks ago. You want to look for a 12 volt nominal panel, PWM controller, and aluminum frame around the panel to bolt to the mounts, and to the roof.
2" angle aluminum 6" long will mount them to the roof. 3- 3/16: holes for #10 screws into the roof, and 5/16" hole for a 1/4" bolt into the panel frame.
Good luck,
Fred.
