<DIV><FONT size=2 face=Arial>See page 29 of the SB7000TL manual for grounding
requirements and page 30 for a schematic. Both the pos and neg are disconnected
in the DC disco that comes with the SB7kTL. One problem that we recently ran
into is that the TL makes WAY more noise upon start-up and shut-down than the
non-TL so do not mount the inverter next to any noise-sensitive area such as a
bedroom. The installation manual mentions this very slightly (insufficiently).
Seriously, WAY more noise.</FONT></DIV>

style="FONT-FAMILY: Arial; FONT-SIZE: 10pt">I have yet to do a
Transformer-less inverter and am understanding that they are an ungrounded
system and that both the positive and negative of each string will need to be
disconnected. I started with the sma SB series and now find myself using
mainly Enphase. The SMA TL dual mppt lighter weight inverter has my attention,
especially with AB327 Knocking on the door but that's another
topic.<o:p></o:p></SPAN></FONT></P>
