Inverter

[AMK]

what size inverter do you funsters use to power a small hair dryer and a Hair Straitner.

Your recommendations would be appreciated to make sure I buy the correct size.

I have two batteries and solar so charging is ok, and it would only be used a couple of times a week when travelling and staying on Aires.

If you look for a dryer of about 1500w then a 2000w inverter will do but I would go for a Pure Sine Inverter otherwise you may damage any electronics in the dryer or straightener. A normal Inverter wrecks electric toothbrushes.

2000w at 12v = 166A so you will need some real meaty cables and shorter the better to cope with it. Batteries will also take a hammering and a 100A battery will supply enough power for about 15 minutes. It will take some time to put the power back in the battery again.

At the end of this thread there are links to the items I used including the hair dryer. Some of the links probably won't work any more but you should be able to find equivalents.

Ann loves the "Babyliss big hair" hair dryer only 700w and runs off our 1000w psw inverter.
It's not ideal on our single battery but it does have a 350w setting too

I suppose the other problem is how long and thick the hair to be dried is. Using a lower power dryer will take longer than using a higher power one for a shorter length of time.

Looking at the straitners they are only 150w so they aren’t so bad. It’s going to be the dryer that sucks the powe.

Beware though, straighteners have a high start up current. Ann's GHDs wouldn't work on a 475w Victron psw inverter

Thanks for that. I think I will look at fitting a 2000w and find a hair dryer around 800 to 1200w.

She should be able to manage with that.

Doesn’t bother me I have no hair

We made do with a 600w Inverter for the past 7 years,,,
Wife uses the dryer on the low setting, this reduces the heat and hence the power requirement...
Check what dryer you plan to use and that's the most drain, wattage should be stated..

My Dyson hairdryer doesn't work very well using the inverter and I completely fried my brand new GHD tongs. I think much depends on the make and model of the hair care products. My Diva Dinamica (who names these products! ) works fine.

Is it a pure sine wave inverter?

 

[Southdowners]

Yes it is.

I found it strange that some haircare products work and others don't.

You’re very brave telling a lady she should manage, never ever offer advice on things like hairdryer. All women have their own preference and it won’t be anything that you think is right. Haha

 

[AMK]

Brave or stupid.

Even more worried now, if I fry her GHDs after all this work I’m a dead man.

This could be hero to vilen in one small project.

I wouldn't use the GHDs with the inverter. When I said I fried mine, I really did. They were only a week old and they were completely useless... you don't get a second chance if it happens they just die. I think your wife may be a little less than happy if it happens to hers too!

We use a pure sine wave inverter for straighteners and dryer. It works ok so far and the other half is happy.

If you want your batteries to last need best not to take much more than 20 amps out of each battery.
