<DIV>You will need to install MPPT trackers from TIGO and SOLAR MAGIC on all of
your modules, and not just the string in question... as far as I have been
told. I have asked both outfits the same question - and was interested in
SunMizer for this very reason.</DIV>
<DIV>But SunMizer seems to be going through a change, or perhaps
chrysalis. One can only wonder.</DIV>
<DIV>Maybe you could use Enphase for just the modules in question, and use
a smaller string inverter for the balance.</DIV>

designing a 4KW res system which has limited roof space and <BR>would like to

voltage needs. However, this would necessitate placing <BR>2-3-maybe 4
PVs (in one string, of two string total) in a location which <BR>would recieve
shade from the second story from about sunrise until, say <BR>10:30
PDT.<BR><BR> I'm not interested in going individual
inverters on all PVs, but <BR>would appreciate feedback on the use of
module level MPPT trackers such as <BR>Tigo or Solar Magic, or?? only
installed on the shade affected PVs? Or <BR>must they be installed on
all PVs in that string....or both strings??<BR><BR>Thanks in
