Given some cables

[Chispas]

I’ve been given some cable & I’m wondering if it’s worth it to buy a crimper, maybe a hammer one ? My upcoming project will need some short runs from the panels, at max about 4 M & then battery cables to the busbars & inverter. Spanish panels come fitted with mc4 connections & cutting them will void the warranty. The smaller cable is about 5mm diameter. 20 csa. So I won’t be able to fit mc4s . Is this getting too messy? The big cable is about 6 to 7 mm in diameter, haven’t measured properly yet. I will have to buy or make up some mc4 cables to the breakers but from there to the SCC I can maybe use this?

Is there anything printed on the outside of the cables?

So 1 Kv rated, 16mm2 and 90 c temp rating??? Une is the Spanish standard & I think 16mm2 is for meter tails up to 80A what does the temp range mean exactly? Ambient or temperature of the conductor?

The basic outline for the project is 2 sets of 2 x 600 W panels, 24 v nominal, 2 x SCCs & 2 x 100AH lfp in parallel. The longest run from the panels is about 5 or 6 M. The panels ive looked at are about 54 V VOC ISC about 15, I think.
