She's probably long gone.
Off the top of my head, 190W solar + you add another 100W, in December in AZ on a sunny day will barely harvest enough to run 110V fridge and critically important loads like lights, pumps and furnace. Need to measure duty cycle of the fridge. Might have to stop using coffee maker and microwave.
The easiest solution for technically naive would be replacing your marine batteries with something larger, if it fits.
Jackery has 2-posts red-black port to connect their proprietary 100W or 200W solar panel, however such a portable solution seems inconvenient. And ridiculously expensive @ $300 per 100W panel. And easily steal-able. And inefficient, can't charge on the road. And small, one half of usable charge of the pair of your marine batteries. This gizmo is more for a weekend warrior, think car camping.
