Iโm not sure I understand REDARCโs answer; but the gist of it is, hooking the WFCO to the REDARC wonโt work. So Iโm going to let it be for sure.
Here is their answer:
โIf you connect the WFCO only to the input of the BCDC1240D, this will not work.
The BCDC1240D is looking for battery voltage, and the WFCO is looking for a voltage in order to supply power โ the BCDC1240D does not have battery voltage on the input without a battery connected.
If you had both the truck and the WFCO on the input, the BCDC1240D would turn on under normal voltage thresholds once the truck reached 13.2V, and start drawing the current required to charge the auxiliary battery.
If the WFCO could keep up with the current requirements to charge the truck battery, and sustain amperage required to charge the auxiliary battery, this would work just fine.โ

Also, the OPโs Redarc model and the 25 amp version Iโm using have a built-in MPPT solar controller and a separate input wire for the panels.

"Charging from one source at a time is always the most ideal circumstance, as two charging sources at once can cause early float stages, and an incomplete charge.โI can see this happening if both chargers are smart enough. They may trick each other into thinking the battery is charged.

The first problem I see to connecting the WFCOโs output to the Redarc โs input is you will be limiting your maximum charge rate to 40 amps. Canโt your four AGMโs handle more than that?
Bob, I honestly think the scenario of having the solar controller in the Redarc and the charger in the WFCO trying to charge the batteries at the same time isnโt the problem you may think it is. Your panels canโt force 40 amps into the batteries if they arenโt at a state of charge that will accept it. So what if they both sit there in float for a few hours? Eventually the sun is going to go down, and the panels will stop producing power. Then the WFCO charger will go into bulk if the batteries need it. Except, youโre on shore power, so why would the batteries need any more than float anyway?

While the Redarc install instructions donโt directly address the multiple charging devices that could exist in an RV, they do state that the Redarc input wire should be connected to an appropriately sized wire going to the truckโs battery (not the alternator), and the output should be connected directly to the auxiliary battery it will be charging, and as close as possible to it. Thatโs how I installed mine.

- second question is, with live power coming from the WFCO and the TRUCK/SOLAR at the same time (wired together at the DC input of the BCDC), will everything play nice, or will something burn up or catch on fire?
