What size generator for a horse float/camper

Hi there, Wez. Some thoughts: you could consider using 12v from a battery to supply the flouros, the Waeco, the portable DVD/TV and the water pump. This would then mean you are able to use those things even without the genny. A battery charger could then be powered by the genny of your choice to recharge the battery. That leaves the 'small fan heater' (about 2200W, most of them are) and the airconditioner (up to 2400W).
On this basis, you probably need to be looking at a 3kW genny min to allow a bit of head room.
Of course, if you are buying a genny to suit these last two items (the heater and the A/C), then the total load of everything else in your list is about 250W, which is within the scope of a 3kW genny.
The problem I see is that if you get a genny for the big loads, it will be seriously 'under-loaded' when it is only poweing the small stuff. If you don't get an inverter generator, it will have to run at full speed to get the voltage and the 50 cycle per second, so you may have a very loisy genny running just to power a few small loads. This is one reason why the 12v solution has some merit.
There's info on this site about choosing a genny (reliability; quality of the power; noise, etc.)
Hope this helps you. By the way, I bought a Yamaha inverter genny, and still think it's worth the extra $1,000 compared to the well-advertised options (like $100 for a 750W machine).

Thanks for that.
We actually have the fluros etc all wired up like a caravan into the float so can't actually be run from a battery - the float just plugs into the 240 power like a caravan or i can flick a switch to run everything from the car (12v). Would prefer not to run from the car over the whole weekend/3 days though.

Hi Wes
You can add Subaru to your Inverter gen list they have good units also all electric start units can come with wireless remote controls if required but they start at around the 3000W mark
All units are covered by Australia Wide Service Locations and any one of them is good reliable value for money.

The first option stated is a good one as it would allow you to downsize the generator and you can offset the 240V lights by installing a small inverter that would allow you to run off batteries and then the generator is more efficient just charging batteries.
The 1700i Subaru ,The Honda 2000EU and the Yamaha 2400i would be workable under that scheme as all will run a standard air con and you can charge up batteries in the off time.
