iCrimp IWS4 Solar PV Connector Crimping Tools for AWG14-10 (2.5/4/6mm²) Solar Panel PV Cable with Wire EDM Die

Have had for years, no issues.

This is a nice crimper. You can tell by the machining on the jaws is smooth and seem wider than some. I just used it on several MC4 crimps on 10 guage solar cables and worked great. Glad I spent a couple more dollars on these.

Used this for the first time today. Didn't know when I ordered it that the wire I had was 8 gauge. The tool says it's good up to 10 gauge. Yet it performed flawlessly. I've tried using these before, and they would all ruin connectors by having a failed crimp. Not one connector was lost when using this tool.

I'm very happy with this ratcheting crimp tool! It makes VERY tight connections between the cables and the connectors. In the past, I've usually soldered these connectors on, but this thing crimps so tight, I don't really feel the need for that, except perhaps for some hard to get to MC4 connections up on the roof which might get some pretty rough wind and weather treatment on top of our RV. I may still solder those after crimping...but that may be over-kill.

Perfect tool for making the mc4 connectors. I’m crimping #10 wire for solar panel connections. 100% crimped every time. Great tool.

Had to makeup several connections & it worked great 4 connections were #8 wire & I did not realize this until i went to fix connections to far out in country to go back & order different one so i went ahead & made crimps, a little tough but it worked

This tool makes perfect crimps every time. You just have to be sure that the proper side of the connector is facing the right way. There are no instructions with the tool but after My first crimp was a disappointment I realized my error and now I'm very pleased!

These are the crimpers you want for solar MC4 connectors! The other ones on amazon are cheaply made. The dies on these look like they’re wire EDM cut, which means they’re very well shaped and defined, unlike other tools where the dies are cast and dull. Spend the extra couple bucks and get these 👍🏼

I’ve tried a few different cheapish ones and this has by far been the best so far, accurate and strong crimp on mc4. There’s a YouTube video made by Staubli that describes the process perfectly for a good crimp everytime

Impeccable, utilisation facile.

Ho sistemato un paio di cavi quindi i si è già ripagata.

A well made tool for crimping solar mc4 connectors. It was a pleasure to use and see the professional result on 6 mm cable. I have only used it about 20 times but I expect it to last as the build quality is good.
