Right now I have 8 Siemens M75 48W panels hooked up in series and parallel to give me 65V or so directly into my 48V battery bank ( 16 trojan L-16H's ) which works pretty good and powers my huge fridge ( 26cf! ) as well as a computer during the day, we run a generator a few hours at night to do the laundry, watch TV and run the well pump but we'll be hooking up our freezer soon so need some extra juice.
A guy locally is selling 2 year old used Sanyo HIP-200BA19 HIT panels, 200W 40V for $2.25/W which seems like a great price to me but I'm not sure how this would work with my other panels. I know for this I would now need a charge controller, and probably an expensive one to support 48V and MPPT, maybe the Xantrex XW SCC Solar MPPT Charge Controller to match my two 5548 inverters?
Here are the stats on the new panels:
