The inverter is co-located with the panels, so it is DEFFO a/c cable. The quote / invoice says "Solar Flex 4.0mm plus 10mm x 140m cable", and stamped on the outside of the armoured cable is "PK ELECTRIC CABLE 600/1000 V BS 5467" See https://www.basec.org.uk/cables/#BS-5467 . But I agree that none of this confirms the diameter of the internal wires. I had the thing professionally installed and signed off, so will ask them for more info &/or do a physical check.
Do I take it from your maths above (which I do accept is based on limited info) that if the existing is 4mm if I extend with 10mm I could charge at 16A, but if the existing is 10mm if I extend with the same & I could then charge at 32A?
@riverrock - I think you are right with the music - almost certainly #3. The very wet behind the ears (but very pleasant) salesman said it was something to do with the motor &/or regenerating brakes, both seemed unlikely.
EDITED TO ADD: On a secondary invoice it says the wire is "10mm SWA", so I am tempted to think the internal wires are 10mm.
EDITED TO ADD MORE: One reason to want to max out the max charging amps in the garage is for future proofing for when and if we ever become a 2 car BEV family.
