Questions about Renogy DC DC Battery Charger w/ MPPT!

[Jetguy]

I'm installing a Will Prowse 400 Watt Solar Package w/ Alternator Charging System in a 2004 Monaco Motorhome. The only difference is I'm using a
Xantrex Freedom 458 Series Inverter/Charger instead of his pure sine wave inverter. When plugged into ground power the Xantrex will charge the house batteries.
Will's system uses a Renogy DC DC Battery Charger w/ MPPT. A few questions about this unit.
1. With no solar connected to it and no ground power connected with the motorhome's engine running will it still charge the house batteries normally?
2. With the engine off and solar connected and ground power connected to the motorhome and the Xantrex charging the batteries will the Renogy Charger sense this and stop the charge from itself?

Thanks

Yes.

2. With the engine off and solar connected and ground power connected to the motorhome and the Xantrex charging the batteries will the Renogy Charger sense this and stop the charge from itself?

The Renogy will react to the bank voltage it sees. It does not know or care that the other charger is present. Multiple chargers can feed the same bank at once.

When plugged into ground power

The locals around here will often refer to this as "shore power", as the term ground has other meanings in this context.
