Converter and Charger at the same time

Sometimes you have to get the VEC running and then turn on the converter. Depends. No problem just find out how your converter and VEC like to do things.

I'll play around with this to see how they work together. I thought the VEC would always start in bulk mode so it would deliver amps even if the battery was at 13.6 volts.

So what to do with the WFCO? Use it to run the rig 12v while you charge the batts with the VEC with the batts disconnected from the rig (battery disconnect switch open) That is, put the shore power cable into the gen and also plug in the VEC. Open the disconnect Now the VEC can put all 40 amps in while the rig is not drawing some amps at the same time, reducing net amps in, and so increasing gen time.

I assume the reason for disconnecting the battery is because the WFCO won't supply any DC current if the voltage is above 13.6 volts. I don't have a disconnect yet, it's on "the list". I would have to remove the cable at the breaker near the battery. I don't think the DC load will be that high when charging. Maybe 2-6 amps for fans and LED lights.

I guess I can play it by ear. As long as the VEC is at 40 amps, I know that disconnecting the batteries and running the WFCO can help some. If the VEC is running at below 40 amps then I know it's servicing the DC loads and the batteries and disconnecting won't help.
