[RE-wrenches] State of Charge Meter for Sol-Ark

[Dave Angelini Offgrid Solar]

Ask them to do it?  Sometimes it is just a matter of asking. Schneider 
did this because I told a bunch of people to complain.
There are folks who only want to look out the window and see a picture & 
read Soc. It works for them. They are the boss!
