The inverter system, shown here with most of the new equipment installed, has been refactored to handle the new pack.



First of all, the entire 240V, 120V, and also the 12VDC house loads are all run off of this inverter now. That means I had to pull a new supply wire from the rear load panel to the inverter bay, and the shore cord and generator supply wires also terminate in the inverter bay now. There is no standalone transfer switch in this system; the Victron inverter you see on the forward wall there can switch all of the AC inputs internally.

The inverter/charger you see is a 230V/240V inverter that can produce 15kVA of AC continuously at 75F and peak at 30kVA for up to 30 seconds. Because we need 120V, its output goes to the autotransformer you see on the rear wall. That AT can sink 32A of neutral return current, which means up to about 4kW of "imbalance can exist between the two 120V legs of the house power side.

There are 2x1500W 120VAC-to-12VDC converters wired onto the house side of this system. These converters provide the 12VDC for the house loads (Spyder panels, miscellaneous pumps, etc.). Some of the "automotive" side loads are still powered off the pair off the chassis 8DLs in the rear of the coach. Also, the generator starter motor is also now tied to those rear batteries.



So far, the largest load I have been able to create is about 16000W: the aquahot, all of the electric space heaters, several of the roof heat pumps, and some lighting. Smooth sailing.
