6.48KW bi-modal (grid-tie w/battery) system. 27x Canadian Solar CS6P-240.
Xantrex XW 6048 inverter (Schneider Electric bought Xantrex and is re-branding to Schneider Connext XW)
4x Xantrex MPPT-60 charge controllers
Xantrex AGS + SCP + XW-Config
Honda EU-6500IS Generator

16x Surrette S-530 batteries, each string with its own set of inverter cables in their own enclosure (lifetime extra-large deck box). If the Surrette 500-EX were out at the time, I've would have gotten those instead. They are series 4500. Essentially a series 5000 battery in a L-16 size series 4000 single-walled container.

System is pre-engineered (wire size, conduit size, reserved wall space for 2nd inverter) to be expanded to 48-52 panels and 2 inverters. 12 panels will be non-roof mounted (ground, pole, tracking pole, wind turbine with tracking solar in order of $$$). 10 year timeline.

Installation: James Crutchfield of Pharaoh electric is a very skilled union (predominantly commercial) electrician but he's only done 4 solar systems before and they were all straight grid tie. The solar design (james had a large input on the electrical side), device configuration, plans, SRP paperwork, and installation of the network-related low-voltage were all DIY by me (I actually had to take a couple days off of work to guide him on where to put the wires in the PDP). James, with two helpers, did the racking, panels, the electrical work (with two helpers, and was 80% of the work), and battery wiring. Trever did the customizations to the GS2000 shed for the generator and the LifeTime X-Large Deck Boxes for the batteries (fans, vents, exhaust kit). James called in Mike Green to help with the low voltage from the AGS to the generator.

Cost: $24K for PV solar materials, $16.5K for PV & subpanel & generator installation and electrical materials, $9.5k for Solar hot water materials and installation (different contractor), $5K for generator materials (incl housing). The PV costs include batteries, subpanel, standoffs, tilt mounts, oversized wiring, and excessive number (twelve) of lightning arrestors to protect my inverter, charge controllers, and house circuits from lightning and solar flare / CME.

My March 2013 electric bill (Feb 10 - Mar 10) was about 250KWh (-77KWh on-peak, +332KWh off-peak, +255KWh net, 56.7 Avg Temp) with rooftop solar but without community solar (I also have 4KW of community solar, which is essentially leased grid-tie with uncertain inflation resilience; I will keep it until I expand or until prices climb too fast; it is currently $24/mo/KW-block). My March 2012 usage was 1660 KW-h (60.6 Avg Temp) and my March 2011 usage was 1396 KW-h (59.5 avg temp)
