[RE-wrenches] Adding battery to grid tie

When I do this I tend to use an A or B switch for high voltage solar and 
then use a battery based with high voltage mppt or more commonly now, an 
all in one battery/inverter/HV mppt. My clients mostly are technical and 
can comprehend. I am lucky to have them!

The panel wiring to automate can be expensive to do. Go manual!  And so 
if the client is up for it technically and wants to keep cash in pocket, 
the Florida hurricane tap is great. You can't do any of this with big 
systems and non technical people.

Good Luck Man!
