Welcome back, Mark, I for one have missed you.
I did a smaller scale version of your solar power project some years ago - it was a major undertaking though, not so much to build it as to keep the vast bank of storage cells healthy. Deep cycling once per year was probably the biggest single hassle - it took the 8.5 kVA diesel generator about 14 hours at 50% load to recharge it, IIRC. (I could only charge at 115 Amps through my 24 Volt ex-forklift battery charger.)
Unfortunately it is not a suitable topic for Outdoorking, but I wish you good fortune in both playing with it and benefiting from it.
