I bought a cheap 800w hair dryer for our camper. The inverter is rated at 1200w max and this was the lowest power hair dryer that I could find.

Watching the app for the victron inverter it shows 850+ kva then triggers the over power alarm and shuts down, I guess the dryer is spiking its power.


I wondered if I could fit something in the power line almost like a dimmer control to try and drop it to 600watts? If not I will need to explore lower power hair dryers or rechargeable ones

The 800w toaster works perfectly fine.

a hair dryer is an inductive load which will have a current inrush on start up of multiples of the normal operating current. this is what is tripping the breaker.

oridinarily you'd fit a soft starter to loads that risked tripping on inrush current - large a/c units and the like. not sure if there would be one small enough for a hair dryer.

Thanks, it’s odd as it runs for about 20 seconds then trips, not on main start up and this is in setting 1 not 2 although that may just be fan speed.

Not that I have found. A few cordless rechargeable ones but unsure of how good those would be and quite pricey to just try. I have a small generator that hooks up so I think that will run it if needs be. It’s only for when my daughter has a party to go to when we are out competing

You can get soft start units (basically a fairly big capacitor which discharges to cope with the peak inrush current and then gets replenished slowly once things have settled) but they're not cheap, at least £100.

TBH I'd just run the generator if it's for very occasional use.

Thank you all.

Yes, doesn’t seem worth spending loads for very occasional use. Genie it is!


Appreciate the help
