Re: Any gurus on solar panels for charging batteries?
Sure... there are devices that have both a solar charge controller for a battery bank, and an inverter for supplying AC current, all built in. You can also get a pretty inexpensive transfer switch that can supply power only to circuits in your house you select.
Is the array that is currently on your roof active and being used for anything? Do you know what the PV system voltage is?
Here are some examples of devices:
Solar inverter:

Transfer switch (this is the one I have in my house for running the fridge, internet, one of the split AC units, and my office on generator):

Good Lithium batteries are about $750-1000 per kWh these days, so how many of them you need just depends on what you have to run, how long you want to run it, and what your battery system voltage needs to be.
If this is in the "cost prohibitive" area, you can do something more simple like a standalone solar controller and inverter with household plugs and probably spend half as much. It just depends on what voltage your PV array is putting out.
