Finally got the STXR replacement in for my ST1500! I guess it took a little longer than Xantrex anticipated. I replaced the ST1500 about four months ago with a SB2500; this STXR one will get put on an 'auxiliary' array on a SW facing roof. It will be an odd array, made up of the spare parts from an old guerilla system. There will, so far, be two strings:

- Two Sharp 185 watt panels (24v panels)
- Three Astropower 7105's and one Shell SP75 in series (all 12v panels.) They're pretty well matched spec-wise.

I'll add to it as I find mates to my motley collection of old PV panels. It will be interesting to see if the different models of panels 'play nice' with each other.
