Am I being belts & braces using 16mm cable to run between a Victron MPTT & my leisure battery? And should I put a fuse in the +ve cable?

That's good for about 110A / 1400W of panels...16mm cable to run between a Victron MPTT & my leisure battery?
That is definitely OTT. The cable, if you have 1 panel is carrying no more current than the wiring to your 12 v sockets which are fused at 15/20 amps and the sockets rated for 20 amps.Am I being belts & braces using 16mm cable to run between a Victron MPTT & my leisure battery?

I have 360W of solar. I would have thought 6mm sufficient.That is definitely OTT. The cable, if you have 1 panel is carrying no more current than the wiring to your 12 v sockets which are fused at 15/20 amps and the sockets rated for 20 amps.
Under absolute ideal conditions and 100% efficiency the MPPT will be pushing out no more than 10 amps.
And yes, fuse at 10/15amps for 1 panel.
Please tell me you need all that solar to recharge your cordless chainsaw batteries and it’s not for a hair dryer…I have 360W of solar. I would have thought 6mm sufficient.
Just lost by the suggestions on Victron kits. See previous
Hair straighteners. And foot spa.Please tell me you need all that solar to recharge your cordless chainsaw batteries and it’s not for a hair dryer…
I concur. Which is why I was scratching my head.I have 360W of solar. I would have thought 6mm sufficient.

I would agree - a bit of both. 6AWG is definitely a sledgehammer to crack a walnut. With a 1.5m - 2m of cable max to the rear leisure battery, 10 AWG would probably be enough. 8AWG if you felt keen.The size maybe to minimise the voltage drop and not just for the current capacity.
