Just purchased a 2000w pure sine wave inverter . Do I need a fuse between it and the battery bank and what size fuse if any would you recommend. Would have read the instructions but it didn't come with any , (second hand but never used).
Some are internally fused (projecta for example), so as long as it is fitted close to the batteries with adequately sized cable, you may not need one.
What is the brand and model number of the inverter Mick?

You need a 200 amp fuse between the inverter and the battery and use battery cable to connect it all up keeping the inverter close to the battery as possible jaycar sell the fuse

Not necessarily. If the inverter is internally fused like the Projectas, and it is fitted within a foot or two of the battery (which is the better idea), using something like 1 or 0 B&S cable and no likelyhood of the cable being damaged by metal edges, then the internal (12 X 20A fuses in the Projecta) will suffice.
No point in theorising anyway, till the OP gives some details about which inverter he has.

It is a bit like towing a box trailer with a truck, but it should do it OK, but how much power does it use to do that little job. Be interesting to know. I would turn it off when not in use to limit losses.
I only turn it on for Foxtel when free camping not sure what it draws but if I ever needed it to use on other appliances it's there , as for overkill ,well $50 well spent but I still would like to know if I need a fuse between it and the batteries.
Thanks

If you only want a inverter to power for Foxtel then all you need is 300w one and leave it attached to battery and keep Foxtel unit plugged in, this way you don't have to reboot all the time. Works for friends who I setup their inverter for Foxtel, just pull up setup aerial and off it goes.

what inverter would you suggest for a motorhome. Mainly it would be to charge laptops I guess.
That's what I could think of, but we are new to long distance travelling so I might have missed something.
If you are only charging laptops, as I do. You do not need an inverter, as I do not have one
Just look on your 240 volt charging cable box. It will say something like Input 100 - 240V - 1.5A Output 19V - 3.42A
From Jaycar, or a similar shop you can buy a 12 volt DC adaptor charger that says something like Input DC 10 - 15V max 10A Output 19V - 3.42A
You can see from the above two specification, the the Output is the same for both the 240 volt, and 12 volt, chargers It does not have to be the same brand as the laptop
If you take your 240 volt cable charger box in to an electrical shop, and ask for something of the same specifications to charge the laptop from a 12 volt ciggy connection, they will know what you mean From memory they cost about $70
I just fixed a double female ciggy socket to the wall, for ease of charging. I took both the positive and negative wires, direct from the house batteries, with a 10 amp fuse on the positive wire, close to the batteries I have no problems charging the laptop and phone, while having the satellite TV on
