<DIV>Jay,</DIV>
<DIV> </DIV>
<DIV> One other consideration to mitigate
morning/afternoon shading is to wire the array one string east side, one string
west side and use an SMA TL with its 2 separate tracking inputs. This is
assuming your shading is from east and west located obstacles...as the morning
sun hits the west string, you'll have full output in that string, esp with
opti-track. Same in afternoon. Not quite as granular as micros or
optimizers but an option. Simple. You'll also have 1500 watts of power
without batteries when the grid fails.</DIV>

<P dir=ltr>Jay you also might consider Solar Edge optimizers for partial shade
mitigation. Same effect as micro inverters...easy to implememt.</P>

<DIV><BR>HI All,<BR><BR>What is the recommendation for 72 cell 280
watt 120/240v micro inverters?<BR><BR>Enphase don\u2019t have
one.<BR><BR>This is on my old house. Still has a AEI-GC-1000.<BR>The
modules have got to come off as well as they are old mobil\u2019s.<BR>All just
about dead.<BR><BR>I\u2019ve got a good deal on 72cell, 280 watt modules, so
trying to find a micro for that or maybe a small <BR>And its only for
1500-2000 watts max. Thats all I can
fit.<BR><BR>thanks<BR>jay<BR><BR><BR><BR><BR><BR>_______________________________________________<BR>List
