Just flagged this up today 3000w inverter may be worth a punt.

I'm just in the process of getting this >>>1100/2200watt Inverter <<<, the cables are going to be 35mm2, with 100 amp fuses.

You might want to do the calculations on what you'll need, there's more to it than price.

How many batteries do you plan to carry Biggy? 8O

If you do the sums you may well go a bit lukewarm on the idea? :? :wink:

For that kind of money you might as well buy a bloody Generator!

What do you have in there that needs this kind of juice? And as others have hinted at, what kind of batteries do you have that can SUPPLY that kind of juice!

Totally useless, you would flatten any combination of batteries in minutes if you use it at high load.

Get a genny, or a smaller inverter or both.

Hi if it gets a 2200watt drain it will blow your 100amp fuses in a second, I would suggest 300amp fuses, and 40mm2 cable

Yeah just what we need another different opinion :lol: :lol:
It's not a 2.2kw it'a 1.1kw with 2.2kw surge, it's all there if you bother to read it properly, which is the reason I posted the link for Bigfoot, and the fuse/cable rating is correct.

Remember Power Out = Power In (ignoring inverter losses)

If the power out is 1100w, then the power in is at least that which is 92 amps at 12 volts.

Most leisure batteries are ~85 ah and so will supply 85 amps for 1 hour, so at 92 amps you'll flatten your battery in just over an hour with a 1.1kw loading....and you'll overheat the battery and distort the plates at prolonged high currents.

Kev a 2.2kv surge will blow a 100amp fuse, thats why I suggested a 300amp.

This from the REUK site: http://www.reuk.co.uk/Fuses-for-Power-Inverters.htm
However most 1,000 Watt rated inverters can supply 2,000 Watts for a short period (10 seconds typically) in order that appliances such as pumps which need a burst of high current to get started can be used. Within 10 seconds a standard 100 Amp fuse would have long since burnt out, and so a 200 Amp fuse would have to be used for such an inverter. BUT, specialist inverter fuses have two ratings - a continuous rating and a blow rating. With this type of fuse, a 100 Amp continuous rated fuse would be perfect.

They then suggest a "Mega Fuse" as a cheaper alternative.

A 125A Mega Fuse available in the UK for around £5.00. As with all Mega Fuses, the blow rating is double that of the continuous rating making them perfect for use with inverters. This 125 Amp fuse could easily be used with a 1,000 Watt rated inverter connected to a 12 Volt battery bank.

Olly...I recognise your MH and Micra from Hurley over May Day...hope you got free nights like we did for the no water fiasco!

Gentlemen and ladies.
I have no desire to purchase such an invertor,I received the notification from Maplins,and thought to pass it on in case anyone is interested. I have 2x110 batteries which is sufficient for my needs. I do not wish to receive Sky Sport inside the Artic circle nor cook a microwave dinner by Lake Gardia.
My years camping since a young boy and motorhoming with my parents have taught me proper stewardship of power and water. If I wanted all the comforts of home I would stay at home.

Says it all Biggy!

Motorhomes, and lots of other things, are getting just too sophisticated.

Not that I really want to bring back the little rubber doughnut you had to stamp on to run the cold (and only) tap! 8O :lol: :lol:

And we thought that was brilliant when it first came out! :roll:

somebodies bus pass is showing.

:twisted: :twisted: :twisted:

As for Olleys advice, after having looked a the link he gave it makes a lot of sense to go down the mega fuse route, it's a little more expensive, but a good Idea.

Thanks Olley (is that because you're a wise owl then)

I have had Hank the Tank for a year now and I think we have learned a lot in that year and as we wild camp a lot have learnt the need to reserve battery power. What I am intrigued to know is what anyone would want a bloody great invertor for. What high powered devices would you want to power? Am I missing out on something here cos I cant think of anything we have missed that dont work of 12v.

Just found some 100 amp mega fuses on Ebay £1.95 (item No = 250415786596) just need to find 3 holders now.
