Help with Inverter cables

[Rjcamper]

Hi all,
Picked up an inverter, now the cables supplied clamp onto battery, I want to wire direct to the leisure battery (Have spare point on the battery clamp) with a fuse and possibly a switch.

Now the cables supplied are only 500mm long and the location I want the inverter is approx 3m from the battery, can any gurus on here calculate the size of cable I need? I also saw a post on here (cant find it now!!) where the cables where split with a connector, as it would be good to have plugged in when I need it and not all the time?? I am thinking 25mm cables but just need to check with you all on here

This is only going to be used occasionally for a 1000w hair dry and possibly an iron when we are on longer trips, have tested directed on my car battery and all works well.

I have pasted below the techie bits from the manual:

Peak power: 5000W
Rated power: 2000W
Digital display: input / output voltage
Input voltage: DC 12V
Output voltage: AC 220V
No-load current: < 0.9A

Thanks all in advance

Have had a good read of DBK thread https://www.motorhomefun.co.uk/forum/threads/fitting-a-1500w-inverter.156023/

This is only my opinion but I would put the inverter as close to the batteries as you can and then run a cable for your socket to wherever you need it. That way you will not be needing to heavy Gauge cables to the inverter.

At 3mtrs from battery to inverter you're going to need very, very heavy cables..... 50mm2 maybe, which probably won't fit the inverter terminals, depending on the inverter output. .
Keep the inverter near the battery and extend the output to where its needed.

The inverter is a cheapie, as want to test use etc before splashing out so has three plugs and 4 usb's built into the case, would an standard extension lead work if I keep invert close to battery?
