depends on how the dealer set up the Inverter. I have a 12dvc coming from the Magnum but the breaker for the distribution panel is off for the AC/DC converter that in the brown plastic box with the AC power in the kitchen. The Magnum was capable of float, bulk and equalize for flooded and AGM battery charging profiles, the progressive didn't have any options for battery types.
As far as the inverter all you would need to do is splice the feed through at the inverter and remove the fuse in the front basement on the 12vdc. I would NOT go without a battery , even just a group 24 is all you need.
