My set up could be improved but, I can live well, as equipped
3x200AMPs house batteries, 2x130 amp solar panels, 12 vt, 8.9 cu ft refrigerator, 1500amp inverter. I have an additional 2 small inverters to run the 2 TVs.
Maybe I should have put in a 2000 amp inverter but, if I had, I would not be so cheap with the power and draw down the house batteries faster. I have switches moving the microwave to the inverter and another switch that moves the inverter power to the 2 galley 120 outlets. No additional room for more solar panels.
Even at the dock and plugged in, if I run 2 stove burners and micro wave on shore power, everything goes dark when the hot water heater turns on. That's the down side of a 30 amp boat.
Of course I have a 6kw genny too. I think my system is pretty much bullet proof. My thoughts about the generator are, you have one, why not use it. SHRUG If you dont have a generator, why not. During the hurricane, the marina and the multi million dollar condos went dark and no A/C. I sat inside the boat, generator running, tv's A/C, drinking hot coffee, hot shower and eating hot food. (If I wanted to go 'camping', I would have joined the army. SMILE) Of course, because we are on the same feed as the hospital at the end of the street, we lost power for only maybe 20 hours. For me, those 20 hours were not bad.
When I leave the boat for an extended period of time, I shut off the 2 small inverters and the big inverter.
I dont worry about someone unplugging my shore power..... the 12vt refrigeratory keeps the food safe and fresh. I am going to install a StainlessLobster on the fridge.

I'm done but, I forgot the original question. Maybe this was a "you show me your's and I will show you mine" situation?
