Jay,
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.

Jay you also might consider Solar Edge optimizers for partial shade mitigation. Same effect as micro inverters...easy to implememt.

Thanks all for the great info.
I’ve got some pretty good morning afternoon shading so micros make better sense than the Galvo, but I”ll check that out.
And I’ve got some really great pricing on some 72 cell 280 watt modules.
Yea I’ve heard the ABB are a nightmare.
I’ve got no experience or info on the APS. Anybody else have any besides Benn?
Thanks all,
jay

We would NOT recommend the ABB micro 3.0 inverters because of the problems with their wireless interface and router incompatibility.
The install of 48 Suntech 300w modules went well, but there were 30 hours involved in hooking up the communications interface.
In the end, ABB tech support had us abandon the normal interface for a signal of over wire home-brew set up.

HI All,
What is the recommendation for 72 cell 280 watt 120/240v micro inverters?
Enphase don’t have one.
This is on my old house. Still has a AEI-GC-1000.
The modules have got to come off as well as they are old mobil’s.
All just about dead.
I’ve got a good deal on 72cell, 280 watt modules, so trying to find a micro for that or maybe a small
And its only for 1500-2000 watts max. Thats all I can fit.
thanks
jay
