So basically, I do have to have separate setups? So like I said in my previous reply, 6-8 panels on one controller and battery bank. If I wanted more than that, I'd have to buy another controller and batter bank to have more than 6-8 panels. So therefore, that would multiply it to 12-16 panels on two controllers and two battery banks. Is that what you all are saying?

The remaining one of a kind panel may be usable as part of that setup. but probably not.SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment

Additionally when you have more than 2 parallel strings you are going to need a Combiner$, Fuse$. A 80 Amp MPPT Controller has the following panel wattage input limitation verse battery voltages:
1000 Watts @ 12 Volt Battery
2000 Watts @ 24 Volt Battery
4000 Watts @ 48 Volt Battery
You have very expensive battery panels that cost you roughly 2 to 3 times more than higher wattage and higher voltage Grid Tied Panels. You could have bought 6 x 200 watt panels and made two parallel strings. Half the racking, hardware, and material. You paid a whole lot more than you needed to.
Lastly at at 1200 watts you can go with 24 or 48 volt batteries and you NEVER EVER want to use parallel battery strings. Instead of 5 years of service is you parallel them you get 2 or 3 years. Batteries have minimum Charge Current requirements and with you need at least C/10 Charge Current to even stand a chance of keeping lead acid batteries charged up with solar, and that is not likely to do it. All C/10 means is C = the battery AH capacity divided by 10 Hours. So with a 1200 watt panel system you need at least 500 AH batteries @ 24 volts, or 250 AH @ 48 volts. Given that it is a no brainer to go 48 volts because you would only need a much less expensive 25 amp charge controller vs 50 amps @ 24 volts. Either way is a 700 pound $2000 battery you get to replace every 5 years or so.
So let's clear up some of your confusion as money makes things crystal clear. Anything you take off grid from commercial power from the POCO is going to cost you 5 to 10 more for power, very limited power in battery cost alone. Nothing else included like panels, controllers, hardware and such things. So do you really need solar?
If you answered; I am doing this to save money and/or mother earth, forget it because you just volunteered for a huge rate increase and became an extremely heavy polluter with a huge carbon footprint depriving future generations of limited resources.MSEE, PEComment

Hopefully, it'll all come through. The eBay user has really good ratings from several people, so I somewhat believe this one. I could understand if they had just two people saying they did great, but when it's from 70-80 people I don't think it's a scam. They only thing I don't like is they didn't provide tracking. We can hope for the best!
Brandon, For your sake I hope I'm wrong. They have a very limited amount if positive feedback, (this can be created artificially) and a very short track record.
I won't give you the old "I told you so" but I would be very interested how this turns out.

Sorry to inform you but what you bought is a bunch of crap that someone through together to get a sucker to buy.

I just figured micro inverters were cheaper/going to be more efficient , I thought bout selling the stuff off anyways since the kits sell for like $700 a 400 watt kit, figured I'd do it for 500 a kit or something lol...I probably will eventually move into the grid tied system, once I figure out the wiring >.>Last edited by Brandon8791; 01-06-2017, 03:19 PM.Comment
