For those of you who use inverters, what size do you use and what do you use them for?

Have a Bushranger 600 watt fixed to the cargo barrier.

Charging camera and sat phone batteries most of the time on trips. Have used a electric drill in the bush but not that often

If you are only wanting to charge Camera batteries, Laptop etc. then a 300watt unit is a practical investment that will provide you with reasonable flexibility at minimal cost. (square wave unit should suffice)

If you wish to light up the entire camping area, power the getto blaster, run the hair dryer, bread maker, toaster and recharge auto batteries, all at the same time, then I would reaccess the style of Camping one is indulging in :-)

500W power tech pure sine wave from Jaycar.
Used for charging video, laptop, digital camera, phones, etc.
Good for camp lighting.
Handy when in remote areas for power tools too.
Could be used in power outages at home, but haven't yet.

Hi Squizzy would $305 for a 500w pure sine wave power tech be a good price. What did you pay for your's?

$305 is a good price.
You can generally say $1 per watt when talking pure sine wave.

Buy it while at that price.

Hi Truckster, Tootled off to Jaycar yesterday and paid $329 for the 500W Powertech. Looks the goods. Check out the size of the supplied battery cables ! ! Your price sounds pretty good to me ! I have a mod. sine wave 300W unit but will use that for non important items.

300 DSE Pure Sine mounted on the rear cargo barrier.

Only run CPCP.

I charge my toys ( iPod, Phone & Camera ) with 12 volt.

Normally a modified square wave is sufficient for me, but the small ceramic heater on the humidifier on the CPAP ( winter ) requires Pure Sine wave.

150w Pure Sine Wave Jaycar - satellite TV receiver, charge my laptop, charge Makita torch battery, charge Remington shaver.

500w Pure Sine Wave Jaycar - run the washing machine

10w on 240vAC equates normally to about 1.1 amps on 12vDC, so 100w on 240vAC would be approximately 11.0amps on 12vDC

Hi David, Interested in your post re the 500W powertech inverter (pure sine wave) running your washing machine. Is the inverter cat MI-5085 from Jaycar and is your machine a Lemair ? I guess a normal 90 - 100 AH battery would suffice.

GeeTee yes, my washing machine is a Lemair - and have had it running on a 300w inverter. They take less than 300w - around 280w on spin if my memory serves me correctly and 255w washing.
Around 30.0 amps from a 100aH battery is a tad ouch. The rating on a 100Ah is preferably to keep it around 20 amps or 20% of capacity for battery longevity. I do run mine from the 100Ah battery, but I do have 300w of solar going into the battery while the washing machine is on.
Check your battery specifications and see what they recommend.

A modified sine wave is a sawtooth style square wave and only 'approximates' mains power. Pure sine wave is like you get out of your power outlets at home.

Some devices will not run at all from modified sine wave.

Some power supplies and in particular switching (no transformer) power supplies can run hot to very hot to dangeriously hot

Things like electric drills and generally all power tools with a universal style motor will happily run from modified sine wave, heating elements, incandescent light bulbs.

For example my Makita battery charger gets dangerously hot, and my Remington razor charger will not charge at all modified sine wave.

Generally speaking things like laptop power supplies, video and camera battery chargers, satellite receivers, video and DVD players, TV etc. are far better off running from PURE sine wave.
The pure sine wave inverters are generally substantially more efficient than the modified sine wave. The little Jaycar (PowerTech) 150w pure sine wave I use is approximately 92% efficient. Most of the modified sine wave are only in the order of 80% to 85% efficient.

Member Eric(on holidays at the moment) has a 1700W inverter strapped to the cargo barrier of his 80. He runs a complete interpersonal Movie Cinema inside his truck with individual outlets to all passengers and twin cinema(dvd) screens. The sound is loud enough to wake the dead lol

My set up is more simplistic. I run a Pure Sine Wave 150W Powertech(Jaycar) to charge batteries and run the laptop or mechanics fluoro light. Mine lives in the armrest cavity between the front seats

Can't remember what mine is Willie but it lives in the same spot. Is a plain and ordinary one that runs the laptop and chargers and the occasional trouble light. Thinking I will have to get a Pure Sine Wave soon too in the camper.

Miles,

We're running a Digitor 300W modified sine wave inverter, $120 from DSE. Using this run/charge laptop, phone batteries and digi camera battery. Works a treat.
