This and the Solar Edge are interesting options. This system is really small, probably just 6 modules, so the Solar edge won’t work as it needs 8 minimum. The larger TL inverter starts to get expensive, and with any shading I”m going to get outside the min voltage window pretty quickly. The APS micros, are a good price point, do two module with one inverter ( and hopefully two MPPT but I don’t know about that). And even with the optional data interface, its still less expensive than the Galvo 1.5.
As backround, when I installed it, the GC-1000 ( 48vdc input) might have been the only inverter. Or around the same time was maybe the trace, and a bit later the SB2500 came out. thanks jay > On Oct 26, 2015, at 7:24 AM, frenergy <frene...@psln.com> wrote: > > 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.
