net metered system question [RE-wrenches]

[William Miller]

Pals:

Great discussion, thanks.  Here are a few more questions, if I may (I'll
put them in caps to distinguish):

I DON'T RECALL THAT THE SW CAN BE PUT INTO THE SEARCH MODE WHILE IN SELL
MODE CAN IT?  IF THAT WERE THE CASE, THE IDLE CURRENT MIGHT BE REDUCED.

IN OUR AREA, OUTAGES ARE RATHER INFREQUENT.  THEREFORE, A BATTERY BACKUP
INVERTER SYSTEM IS USED FOR BACKUP MAYBE 10 HOURS PER YEAR.  THE ABOVE IDEA
IS ONLY FOR HOME OWNERS THAT MIGHT BE WILLING TO MANUALLY ENGAGE THAT
BACKUP CAPABILITY ON THE RARE OCCASION IT IS NEEDED.
