Hi All, I'm working on converting a Sprinter van into a luxury road cruiser and occasional camper. I have no plans for boondocking so no solar. I have installed a 110v Dometic roof AC unit. My plan is to power it with a secondary alternator which I've already installed. I installed a Nations 280 amp alternator to power my Victron Multiplus 3000 watt inverter. This will power the AC unit. Since we won't be doing off-grid camping I just have 2 100amp AGM batteries for LED lights and such. The question is how to wire this. Can I run the alternator directly to the inverter? Do I run the alternator to the batteries and then to the inverter? If I do that will my alternator be limited to limited voltage because of the batteries? The Nations alternator was specifically designed to charge the AGM batteries but I'm not sure if it will know to send additional power for the inverter draw. HELP!!! And thanks from chilly MN
