This was indeed my greatest concern. However the battery came with pre-crimped very solid DC wires, and nice push connectors for the battery itself. The battery also has an integrated DC breaker (great!).

The system runs 3KW max, so I just added an additional breaker (with RCD integrated) in the conduit box. In NL this is something a DIY-home owner easily can do themselves :) (just use the right solid/flex stranded cabling for the connectors, etc...)

And further, my position has been that learning the correct methods, paying a lot of attention to details, and not being cheap with tools is -still- cheaper and probably more reliable than paying contractors. I have only used my hydraulic crimper for a pair of cables, but it was the correct tool and did good work.

I'm not interfacing with a grid, and there are already code issues with my places- I'd probably feel different if I could get insurance on my place.

Cheap chinese tooling and youtube (plus pretty good general literacy) go a long way in this world.

And FWIW, I live in the US west and am way more worried about fire coming from outside than from the batteries.
