Mother's Day, so only 1 hr today. ;-)

Starting to play with arrangement of the remote boxes...

The 650 is fairly wide and deep, so I probably need to rearrange the remote boxes...

...to be more like this.  But, is there room behind the 650 for the backup battery which is somewhat deep?

I'll leave a 10" wide swath of space for the 650.

I do want to have the boxes out a bit so I can more easily remove them by sliding them down, so they need to be beyond the bottom flange of the sub-panel.
