very new noob Questions victron controller

[billwardak]

i am planning on putting a 24 volt system on my rv. i have a victron 150/100 VE.Can charge controller, looking at purchasing a victron 24v 2x120 multiplus 2 inverter, 2 SOK 24volt batteries and Heliene 60m-310 solar panels. the VOC on the panels is 39.89. so if i understand correctly i can only run three solar panels in series on that controller before needing another one correct? i would love to have as many panels as possible.

For a 24volt system you should be able to run 3 parallel strings of 3 panels on that controller.

try punching the panels specs into victrons controller program.

Are you actually in Alaska? That series string should be reaching 150Voc at about -40degrees. Might be OK in Arizona, but not at the Arctic Circle.

Yes in Alaska lol. North Pole Alaska to be exact.

Really hoping not to be in my motorhome at 40 below though. Lol

So 9 panels total, correct?

You really should take your panel specs and enter them into the above linked Victron mppt calculator. There may be a different controller or a different panel layout that is better suited to those panels and what you want to do.
