We have a 2017 31SL with residential refrigerator, and therefore have a Magnum inverter/charger. My question is this: how are the Magnum and the Progressive Power Converter charging connections to the batteries wired? Are they wired in parallel and both trying to control the battery charging cycle when on shore power? Does anyone have a schematic?
Yes, they work in concert with each other. I did a diagram of the circuit after installing a second inverter & separating the entertainment slide circuit.
It might be a bit confusing, but if you exclude my mods, you can follow it. Let me know if you'd like a copy.

Ken - a copy of your schematic would be great!
Here you go.
If you eliminate "New Junction Box & Single pole switch" going to the inverter, you have the input side of the magnum inverter.
Substitute your battery bank where I have 4 - 6 volt batteries and eliminate "Xantrex Inverter" and you'll have the 12v side.

What kind and size residential refrig did RW squeeze into your 31 SL? You are the first 31SL I have heard of that has a residential refrig. Just curious!

I think I follow your schematic, just might throw out your Xantrex is probably a 2000 Watt inverter not 2000 Amp invert.

Ken,
Right you are, 2000 WATT, not amp!

Maybe I am miss understanding something here. When you have a residential fridge, the factory installs and inverter to operate the fridge on battery power when not plugged into shore power or a generator. The Factory also installs a converter which is a charging system to charge the batteries while plugged into shore power or a generator.
Converters convert the voltage of an electric supply, usually alternating current (AC) to direct current (DC). Inverters convert direct current (DC) to alternating current (AC).

Tony,
You are correct, however, Redwood installs a Magnum 1000 watt pure sine inverter/converter combination unit. The converter portion of this unit is in addition to the dedicated converter. This configuration provides 2 converters.
The nice feature of the magnum is the guage that displays the current load of the converter. It displays amongst other items, bulk charge, float charge, # of input/output amps. This assists in generator run time....you can monitor the charge condition of the batteries. It also displays voltage of the batteries as you use 12v power so you can see how much power is left.
When I boondock and power the whole rig with the inverter, both converters must be turned off. Otherwise the inverter would try to create a 'loop' providing 110v to the converter that would try to charge the batteries with 12v.
To defeat this condition, I installed an on/off switch for the Magnum (see my diagram). I turn the factory provided converter off by turning off the dedicated circuit breaker. To use the generator to recharge the batteries, I must turn one or both of the converters back on to recharge.
