Ok, so here is my first post, and from reading this thread, you guys love to cannibalize new meat, and I am cool with that, as its about dues and respect. I do however have to say that Sunking's comment " I see a fire and explosion in your near future" almost made me require a diaper, it only serves as further proof the need for this thread, as sellers are preying on, and eating off cash lined cadavers . I digress.
I have put up on our blog images of the array, nearing completion. We are a sustainable farm that as you will see practices/walks the line.
For the few that may question the design, it is true north-south with maximum E-W exposure. It is phase 1 of 5 sections I will install, each section will be self independent, isolated and off grid. In part my design was to capture most of our photo day, and limit the exposure of the array to Daryl, Daryl, and Julio, our local gang of bad boys.
Briefly, we are in west central Florida, hurricane central, so everything is overkill built, and low on maintenance. Our primary grid is old, and when its down we are out of power for days to a week, not good for a hydroponic operation. We harvest rain, wind, exhaust, and now sun.
Since I got beat out twice on sustainable energy grants, where I was slated to be funded (politics and the good old boys) approved a farm in the middle of a city for 1MW of solar, when they have 3 cows. So I had to fund this alone and I looked at value and efficiency.
----------------the BUY--------------------------------------
I purchased 2 pallets of Dupont DA080-A2, B grades for under a buck a watt. Panels are blemish fee, but it was an assortment of older/same panel with different MP connectors and 1/2 were black underside the rest white. (look to the panels for harmony) . I went for amorphous cells due to geographic location, other more expensive cells used at local utilities and homes all have issues with heat gain, power loss here in summer.
----------------the WHY-------------------------------------
OK guys, pay attention here, as this is where I drop my shorts for the big attack.
We wired in Parallel each string of 8 @ 80 watts. There are 6 strings. (if we get the max power +,it's possible to be 704w each string)
I purchased a Xantrex XW-MMPT60-150 controller as logically in my mind, it was all I needed.
Balls out max 4224 array watts, over 71 max volts = 59.49 amps, (right???) so then I assumed each string of max output was in the area of 9 amps so, I ordered the 6 string combiner box, I may have screwed up on the fuse sizing, as I went 15A, as the load seemed to close for a 10A, Thoughts???
-----------------the SIGH-------------------------------------
So after you either piss yourself in laughter or send the fire trucks, help my review , ask questions, as I know the comments will be forthcoming, and when you feel compassion, please advise on battery efficiency and sizes, recommendations for best value.
Your new punching bag,
Robert

If you are running anything other than 60 volt battery you might as well throw half or more of your panels away because they are not doing anything.
