Can anyone tell me which size cable I need to use for charge out connection of a 250/60 mppt?
It will charge a 48v bank.
My supplier only sells either 16mm2 or 50mm2. 16 seems quite small to me and 50 might not fit.
Thank you!!

Cable size for Victron 250/60 mppt
The question is more of what is your panel configuration? I have 10x 430W mono panels on a 250/100 and I have two strings of 5x panels. Their Isc is 11A and two strings 22A so cable wise that is the consideration. I have 10mm² cable, Your supplier 16mm² is more than adequate.
In the manual on page 24, it recommends 35mm² or AWG2.
You mean p22 on the actual document and p24 in the pdf soft scroll paging.
I think you misunderstood the documentation. The 35mm² refers to the ENCLOSURE cable capacity and not necessarily the recommended cable sizing. In other words its up to 35mm² on the battery terminal side.
Since I gave a link to a pdf. And not a physical copy. The page number is a given to mean pdf scrolling.
And I stand corrected then on the cable recommended size statement. I apologise if you feel this was misleading. Since it does not categorically state that is recommended cable size.
The mppt can take a maximum of 35mm² on the battery terminal, from experience as we have installed several.
Thank you very much
