aren't you in the car industry? The guys down in the workshop should have something like this lying around if you don't want to buy one yourself: https://www.joom.com/en/products/5febea76e3da9501068f9f0a

Here in USA they told me: "I use a hammer"... :palm:

I used acetylene gas and oxygen flame when I made such connections on the buses.

Thermite perhaps? :D

Crimping is an efficient and highly reliable method to assemble and terminate conductors, and typically provides a stronger, more reliable termination method than that achieved by soldering.[/i]

No. Just no.
Solder joints are more difficult to do correctly, but when done so are almost always the better choice. The vibration point is a good one, but not really applicable for a home solar PV installation, unless you live directly above a seriously active tectonic fault zone.

The "more difficult" part together with vibration which quite often is applicable, will make a proper crimped joint the winner in most practical scenarios. We're talking about something that gets done in awkward positions by people longing not for the ultimate in low resistance but for a pint at the pub.
I have an Elpress (which is the Nice Brand here in Sweden; they do the most popular and approved crimpers for both small wires and coax) crimper that goes to 70mm2; it's a "hardened ball" version so pretty close to the hammer crimper anvil but not as chaotic. Long nice handles and very sexy gunmetal finishing. I've done my UPS battery link cables with it and similar. I would not try soldering in those applications; the heat transfer would be complicated to achieve and cause problems with insulation pooling on the floor..

I have to disagree, a soldered joint is the best one in this instance. I used to look after nearly 200 buses and coaches, all were 24V with 4 huge great 6V batteries all connected in series and the interconnecting links and the leads to and from the batteries and the huge great starter motors all had soldered connections. As all we know, buses in particular are real bone crushers in their riding and so the leads were constantly being subjected to massive vibrations and I never had a single failure of these connections and if you consider not only the jarring harsh ride of buses, but the huge amount of vibrations generated just by the diesel engines themselves and the fairly large amount of engine flexing being brought to bear on the cables in particular on the starter motors and alternators, it stands testimony to the suitability of those cables being soldered.
