    Hi,

    I have just bought a Ford Transit van conversion. I know nothing about electrics and have read that you need an inverter if you want to use a hair dryer, charge laptops etc.

    I am travelling round Europe for a year from May 2013 and on the cold days I want to be able to use a hair dryer. I saw one site mentioned getting a 2100kw Ring inverter so that the power supply is constant.

    The van I have does have normal uk plug sockets, one says 12v and one says 240v.

    Is an inverter the way to go?

    thanks

    Zoe

    Hi .. and welcome ..

    in order to understand we need to do the sums..

    a 2100watt inverter on full load will pull 175amps ..

    your battery capacity is what ? .. say 85ah .. ? it's useful capaity is 40ah

    that means it can in theory supply 1amp for 40hrs .. or 40amps for 1 hour .. 80 amps for 30 mins ... 160 amps for 15 mins

    so how long would it last pulling 175 amps ... less than 15mins and it would be kaput

    that is just theory.. in actual practice it would be dead long before that, leisure batteries can't provide a high current for a long time,they are designed for small currents (amps) over long periods..

    so in answer to your question.. if you want to charge phones, cameras etc ... buy either a small 150watt inverter.. or a 12v adapter with a selectable DC output and tips to suit your toys.. that is more efficient than an inverter.

    Forget using an inverter to provide space heating.. ie hair dryer or fan heater .. gas is the best way to heat the van unless you are on a site electrical hook up ..

    Nothing like disagreeing;:Smile:

    I do use an inverter to run a hairdrier (and a toaster and in summer an electric kettle)

    I have 2 125Ah batteries with a 1.5Kw inverter (Max current around 150A). This is enough to run a travel hairdrier (1200w) and while doing so will draw around 100A.
    My batteries will theoretically run the hairdryer for half an hour but it only takes less than 5 mins to dry Shirleys hair (and even less for mine!) so at worst we are using 17Ah a day.

    In addition my solar panels will replace the lost charge at the worst in four hours and at the best in less than an hour. So perfectly practical as long as you either have adequate solar or a BtoB charger.

    Not trying to say that at all, everything in your reply is correct, but there are ways round it.:thumb:
    and even I have not found a practical way to run a fan heater, though it will run off the inverter you won't keep warm for long!

    given that we don't know what size of battery the OP has, nor did he mentioned a solar panel.. and more importantly has no knowledge of electrics .. I thought my advice sound..

    yes.. you can do it with a large battery bank and solar .. I was trying to keep it simple for him.

    I have run 2 systems in the in the past to run a hairdryer from an inverter.
    System 1 was a large inverter hotwired into its own separate battery completely separate from the house batteries and charged by a Cetek relay from any excess that the solar bank produced. This way the house batteries are not compromised.

    System 2 is what am running now, which is a 1.5kw pure sine inverter which is built into the MH and hotwired through a shunt and driven by a 330 amp battery bank. This system runs to all plug sockets when not on hookup and is only used sparingly for occasional microwave and hairdryer use. All other items ie, laptop,phone TV etc are run directly from 12 volt.

    This too is my system with the addition of a relay to allow to be plugged in to electrics and shift power from one to the other.

    I dont have hair, so need for a hairdryer, but i have noticed that Nikki is always walking around with clean dry hair. However, when you cure one problem you invent another. Its the straighteners that are giving us a problem now :Angry:

    And you did Jim, very well explained too. I'll bet Zoe loves being referred to as "Him". :Rofl1:

    Cheapest I can find the RING 2100 inverter is £207 add an extra battery say £80 then £200 for solar that's almost 500 quid to dy hair :Eeek: ever heard of a towel :BigGrin:
    You could save £200 by runnibg the engine whislt drying and doing away with the solar :thumb:

    "The van I have does have normal uk plug sockets, one says 12v and one says 240v."

    Sooooo - are these sockets the same type marked 12 and 240? If so, do you have both 12 volt and 240 volt appliances with the same plug?

    I do not know what will happen when you accidentally plug the 240 volt appliance into the 12 volt socket but when you put the 12 volt appliance plug in the 240 volt socket I would not want to be parked next to you!!!!

    Welcome to the site; all advice offered is good and is from the poster's experience so works for them but we all have different needs hence some of us have VWs and some have RVs! Keep asking and enjoy your new purchase.

    Solaris

    Not really to do with hair dryers but what size solar panels are you using on your camper?

    But what good is this if you have a bog standard system with only one 85 Ah battery and no solar panel? Also I cannot see the significance of a B2B charger. What other battery are you using to charger the depleted battery?

    Surely it is better to get a much smaller inverter plus 12V supply for computer and battery charger,
