A wire ferrule is a simple way to finish off the end of stranded copper wire and prepare it to be used in a screw terminal like you’d find on a charge controller.
Crimping a wire ferrule onto a stranded wire can turn a ugly, high resistance messy wire end into a neat and tidy, low resistance professionally finished wire.

Doing ferrules for the first time with AWG2 and the 150/45 victron charge controller. It says it takes AWG2 but the crimper leaves a non square crimp. Do I just tap this square or how do you work with that?

Hey Nate, There has been a lot of talk about Ferrules, I am wondering if you could touch on then for use in the new push connections on the Victron Multiplus II, there is some confusion out there, and a recent video put out by AM Solar says not to use ferrules in these connections, however the interpretation from the Victron installation manual can go either way. Im sure as a Brand Ambassador you may be privy to the best info. Thanks for your help.

I just looked up the video you're talking about and understand the concern by AM solar. I have not run into that issue yet, but Ferrules are indeed approved for use in the Multiplus by Victron. We actually talked about it in the training I am teaching at yesterday as a good solution for those who are having trouble getting stranded wire into the terminals. I would be surprised if a properly crimped ferrule came loose inside of the Multiplus as once a ferrule is crimped, it is on there REALLY tight. But remember, ferrules are optional... If they are causing more issues than they are fixing; don't use them.

I noticed you use square ferrules vs hex. Do you use square ferrules in round holes? I think the solar panel disconnect you recommend has round holes. It seems like a square ferrule in a round hole would not have many contact points between the ferrule and the hole?

The crimping tools for 6/0 wire are either not available or very long lead times. Searching for just that reveals nothing. Guess we won't be using wire ferrules.
