Not only does it open up the ability to use a pair of 140w panels, it will allow use of some of the higher wattage panels with higher VOCs.
The only cold testing I did saw a panel rated for 36v Voc go over 40v for a short time but I don't think I'd see that normally. It wasn't early with the sun slowly coming up but rather I took a cold panel out and aimed it at the sun at 10 am on a super cold and clear day, hooked everything up and pulled the cover off. That's not going to happen normally, even in the clouds the panel will produce something and warm itself up a bit.
Now I just need to figure out how to sneak a few 12v panels in cus if Honey sees them, I'm dead meat. lol
