That’s too bad, apologies.

You’re running a 48V system in your camper?

Meh, at least I contribute…(and am not off base).
Your contribution in 4 days and 7 pages has been 2 ea 1 liner insults?
Yoo can dooo better than that…cmon bud.

And for all the butt hurt, remember I did not ever say there was anything fundamentally wrong with a higher voltage system. In fact it is more efficient in some ways.
I sometimes make the mistake that I presume that people are after the best balance between cost, performance, durability and value. Served with 2 large sides of practicality.
And I also generally presume that the most apparent cost effective way to competently achieve a particular goal or outcome is desired.
What also I fail to sometimes recognize is there are folks who are just particular about something and prefer it a certain way or “their” way for no obviously advantageous reasons. Heck, I do as well with things. Some things. We all do to some extent.
However, none of this above is “wrong”. Nor would I ever criticize anyone for their preferences generally speaking.
Just state that it’s your preference or you think it’s cool or you recognize that it may not be or isn’t the most cost effective, or something. Because if you don’t, you go from presenting an option to presenting bad information within the context of the question.
Cheers all!

Where’s SiO2 Waldo??

I'm just acknowledging what other members have said..
Maybe those comments made by other members would cease if you dialed back your own insults and arrogance.
Give it a try buddy, it might work to your advantage.

Another Derp comment….
Derp….again!
How do you spend so much time geeking out over this stuff and make a comment like that?
Since you can’t seem to take no for an answer.....

I know residential type ones have large inputs and outputs, but isn't the 150Vdc based on the open circut voltage not the operating voltage to insure it won't damage the controler if there is an issue? at least thats how it was expalained to me so if that is wrong please let me know.
my controler for example has a 100V input but it is rated as a 24V in working voltage, but we all know a 24V panel doesnt put out 24V, for example my 325watt split cell panel has a operating voltage of 33.5 and a open circut voltage of 40.3V. so with my controler which can handle upto 100V input that means I could do two 24V panels in series but not three. although there is no advantage to me doing series on a MPPT, aside from keeping my wire size as small as I can.
that wouldn't be a big deal for me to setup as it is only a 8 foot run, and I believe I oversized it to start with incase I did add a second panel.

Yes, I believe that's correct.. which I've never understood. If panels are connected and operating they are not in an open circuit situation. My 6 panels vary between 80v and around 110 in operation, depending on sunlight conditions.
