Wiring an Invertor

[Cheeky Girl]

Hi
Looking to wiring up a Victron 12v 500Va invertor.
My plan is to connect straight to the battery with a cut off switch and in-line fuse.

I want to bypass the existing switch panel to keep it all simple and to reduce the cable run.
Does this sound ok?
What size of in-line fuse would you recommend?
Thanks for any help.

You should use 10mm2 wiring.

The device is fused at 70 amps but the fuse your talking about protects the wiring to the device, probobly best to fuse this just above say 80 amps as 70 is a bit of a strange rating anyway.

Use a slow blow type fuse like ANL or Midi.

ITYWF 10mm² cable is rated at 70 amps.

70 amp Midi fuses are readily available ( eg from 12volt Planet and Furneaux Riddall

Yep, memory clearly failing me. Even tri rated is 75 amp, I am dully chastising myself.

The cable gauge does of course also depend on the length of the cables with regard to volt drop.

Assuming its a Phœnix inverter rather than a Multiplus inverter/charger Victrom say 6mm² up to 1.5m and 10mm² from 1.5m to 3 m. If I understand the tech data correctly 10mm² is the largest which the terminals will accept

The chassis earth should be ≥ 6 mm² . See also the instructions for creating an earthed neutral.
