After dealing with some battery problems I did some additional research on the AC/Inverter system on the 575 as delivered by the factory.

The inverter on our boat is a Mastervolt MAXCombi charger with a 2.2KW inverter.    The boat is wired for 110V via a Victron Autotansformer 32, which breaks the 220V AC power into 2 legs of 110V.

After looking at the loads I had placed on the system, I found out the following:

The Victron ATR has a bottleneck of 16AMPS on any one leg of the 110V system.   So,  adding up the draw, you cannot exceed this.  On shore power, inverting, or dock power.

The MaxCombi, however,  has a limit of 9.9AMPS of 220VAC  (roughly 2.2KW at 230V) and when you invert this becomes a new limitation.     So..  you need to know what your AC draw adds up to against this 9.9AMPs.   At the 230V inverter level.   In my case,  don't try to run the coffee maker, microwave and TV set at the same time.  Don't even think of running the coffee maker and icemaker at the same time.   

I was overdue in doing this research, as it wasn't a problem before.  This year, however, I added an icemaker to get the 5lb bags of ice out of the freezer drawer and that apparently kicked me over the line and made this a more pressing issue.      I now know what I can run in combination and not in combination.    Two lists:    One when running on dock power or gen set,  and one when inverting.  Different limits.

It seems simple enough,  but you sometimes forget you are on a boat and assume the AC system can support almost anything.    Not the case. 

FWIW
