Yes, that's my setup.  Transfer to/from grid is 1:1 kWh locked in by
power company for life.  Big drive in VA to go solar or 'other'
statewide.  Our last 3 coal stations go offline within 3 years (one a
year).  There are 2 others privately owned smaller coal stations just
for running internal industrial uses and I'm not sure what those
companies may plan.

The majority of the state grid is 'green' energy in a mix-n-match
pattern of nuclear, solar, wind, and I think hydroelectric.  Main
problems here are same as other states.  They all relate to grid power
and EV charging.

The EV charging is pretty bad unless you can do it from home generated
excess.  Some wise-ass said I was wrong on that as 260 EV statitions
show but they were not aware that fully 50% of those are private
company owned for their own delivery vehicles.  120 stations left (all
but 40 are in awkward use areas like paid tourist parking garages or
airport).  Effectively that means 40 to support a population of 1.7m in
Hampton roads.

I know Rome wasn't built in a day but only a fool would not add that
into their EV data when considering purshase of an EV here.

Perfect!  I was about to ask for thoughts on the Jackery setups. On
paper 1 3 panel solar and 2 portable jackery batteries could seemingly
do a lot during a grid outage.  As you say above, grid-down for me
means no power until the grid is up.

Amazon has the system (1 battery so would want a spare) for just under
500$ USD.  In an outage, I could burst cool the chest freezer and use
the other for a DVD player and TV plus USB charging.

With no cut-out switch, during a grid outage that jackery plus a
gas/kerosine old style generator would be it.
