Real world MAX VOC boundaries

[IntoTheWild]

Do you think I would pushing it if I rigged up two of these in series with a 100VOC controller:

87.8 x 1.25 = 109.75VOC

I believe 25% may be a very safe margin of error.

Thoughts?

It is over the limit. Using the 125% rule from codes is extremely liberal, and with using such lenient code rule is still over the limit. Do as you wish, but if you wake up one cool morning and your controller fails, you will know why. Good luck.

EDIT NOTE:

If this is for an RV using on a 12 volt battery system, wire the panels in parallel. Even at 24 volt battery if the wire lengths between the panels is fairly short and/or oversized is quite doable. There is no need to push the limit and takes chances.

Your Voc is 43.9V, 2 in series would be 87.8v @ 70F A chilly morning and you are dead.

Thanks for the advice! Sunking Mike90250

Hi everyone...
Mike90250 says "our Voc is 43.9V, 2 in series would be 87.8v @ 70F A chilly morning and you are dead." but has an vergreen 200w in a 160VOC array???
Just askin like pots and kettles?

He has a Midnite Solar Classic 200. In a 48 volt configuration, with Midnite's Hyper VOC feature he's safe to 248 volts. There are charge controllers that can handle up to 600 volts, if you want to spend the money.

Where did I miss that tidbit of info?

He was asking about Mike90250's Sig line. which shows,

|| Midnight Classic 200 | 10, Evergreen 200w in a 160VOC array ||

|| VEC1093 12V Charger | Maha C401 aa/aaa Charger | SureSine | Sunsaver MPPT 15A

yeah, what littleharbor said.
I've got 2 arrays on the 48V bank. One has a 150V controller and the other a 200V controller. Had to stuff more wires in the conduit, and could not exceed the legal fill factor, so had to increase voltage over 150V. I've seen my 160V nominal array hit 180v on cold mornings, and 154 on hot days. And you don't even need frost. Dark panels, facing the night sky, can, via thermal radiation get colder than the ambient air by a couple degrees, that's how the ancients made ice in the desert, at night , under a clear sky.
