Brilliant tool
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

If you need one, buy this one
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.

Beschreibung passt nicht
Crimpen von Kabeln > 1mm² ist praktisch nicht möglich. Die Verbindungen halten nicht. Extremer Kraft-Aufwand zum Crimpen ist nötig. Nicht wirklich verwendbar.
