Hence the planned electrical upgrade. I really only use shore power (a Honda generator, mostly) when I want to use the microwave.
At the moment, I have: a Renogy inverter, a plug-in 12V charger, two LiFePo batteries, and a 550W Renogy solar panel. To utilize these parts, I have been considering adding a Go Power transfer switch, a solar charger, and a DC-DC charger (hence my other posts asking about removing the battery isolator).

What 12V charger do you have? A modern one with a Lithium profile?
I run my 700W microwave from a 1000W inverter from my house batteries. I had 290Ah of AGM batteries before switching to LiFePo4 and could run it without issue until the AGMs got old ...it still worked but would sag the voltage down to around 11.9V while running.
I now have a 280Ah LiFePo4 and it barely breaks a sweat running the microwave. The 700W microwave draws around 1000W AC.
The LiFePo4 also powers my 12V water heater with ease....that was the biggest struggle with the aging AGMs.
I replaced a Blue Sea ACR with a Victron 30A Orion DC-DC converter when moving to Lithiums. They run hot but work fine.
Is your SMB a penthouse top? 550 W of solar on a penthouse will have it's own challenges.
