Hi all. I know this has been discussed in various other threads about what inverter to get My question is. We need to use a hairdryer about every 3 days maybe for 5 to 10 minutes. So the hairdryer is 1450 watts. I have 300 watts solar panels. 2 batteries 110 ah each B2B Mppt etc. I have seen on eBay inverters 1500 watts.from £ 39.99 to £500 So. What have you or what do you recommend. Must the inverter be connected direct to l batts or can it be used via USB or cig lighter Thanks in advance. Brian.
 
11 yrs ago When we decided to have long stays away all I heard for weeks was how am I going to dry my hair the week before we went shoulder length hair went and I could see her neck.
Now guess what no hair cut for 16 mths because of lockdown and all I'm hearing I've got to get my hair cut
 
1500 wat at 12 volt needs 125 amps ! Way beyond cig lighter at 10 amps and usb at less. A cheap modified sine wave inverter will do it but use thick short cables direct to battery. Someone else will advise more.
For years we have used a hose bodged onto a cab heater outlet. Wash hair before drive off. Drive until heater is hot, push on hose, non driver dries hair.
 
I run 200w of solar and I run a 3kw inverter pure sine wave and with a bit of sun in the morning the wife can use a 1500w hairdryer with no problem when you look at an inverter look at the continuous load not the peak there are a lot about that stat high wattage but the continuous is very low I bought a flamezum inverter off eBay with a remote on off switch it has been excellent I run the fridge on 240 when we go out for the day and the suns out so saves me gas and I can run a 700 Watt microwave
 
In terms of location, I would suggest installing in the same area as the B2B and Bailey Electrical System. You can replace the 10mm Battery-to-B2B cables with bigger ones very easily (size dependant on inverter power) and then spur from B2B to Inverter (not describing it very well - I will do a little picture later on, but it really would be very simple with your layout now)

Inverter size wise ... can the hairdryer be used at a lower wattage? it would widen the options greatly and lower the price a fair bit.
 
Some of the inverters on ebay are putting out a lot less than they say, least would be a 2000w continuous, i would also put a master switch on the pos feed line, battery cables are best, oh and i have a 12v camping h dryer which works well, think its around 400/600w with thickish cables, but ciggy sockets to week for it, best hard wired.
 
This is the one I bought it does what it says on the tin I have also fitted a isolater on the battery positive and I have a change over switch so I switch over from external hook up to inverter which is hard wired into the consumer board

A 1450w hair drier is fine for at home or on hook up.
Mrs S has a similar 1200w folding hair drier to the one posted by Brian C. ( Sassoon) It has a high and low power setting. We have 2x95ah batteries 100w solar and a 1500w pure sine inverter. If Mrs S dries her hair in the morning, we have all day to charge the batteries back up. About 5-7 minutes or so of mostly low setting hardly takes anything out of the batteries.
 
Hi all. Thanks for your answers etc. David showing how thick I am now. In your diagram you say connect to studs. The only studs I know are what plaster board is fixed to So is there another name that I would know the studs as. Also I notice you sell inverters. (Wish I had thought of this last week). Might be buying one of you. Still thinking. Brian
 
I have seen a length of vacuum cleaner hose used fitted into one Truma vent with the others restricted wouldn't cost anything to give it a try
 
Ref studs - It is this kind of thing - https://amzn.to/3eVtImv

The ones above you would stack cables one on top of the other - in your case you would have 3 connectors - one fom battery, one to B2B and one to Inverter.
Also can get busbars, which is the same kind of thing but with a row of studs/bolts instead.
Shame you didn't think of this last week as you said, as I could have setup the cables ready to just connect the inverter to. On the plus side, I do know the cabling routing and cable lengths so could provide what you need for a very straightforward installation - and what you have fitted is not wasted, only the cables will be a bit longer than really needed (no great problem there - just tuck underneath the shelf the B2B is on).
Pure Sine Wave is best type, but if the only use will be a hair drier, then a cheaper MSW - Modified Sine Wave - will do the job for a good saving.

I have not used this make myself but the the Krieger range seems to be well liked and seem a resonable price and has a Remote feature - https://amzn.to/32YWg8X

£135 with a 3 year warranty is a pretty decent deal (I wouldn't say the install kit was a £70 value though! maybe £15 for the cables and fuse/holder, but the remote is dead handy)


I have fitted a couple of Edecoa Inverters and they seem well made and quite hefty (generally weight is good with inverters :)
This 1500W model comes with cables (you would want to add a fuse/holder really) and a remote for under £100

Yep, I rigged same up to the first open vent from my Webesto (Shut all the others for more air) on my boat some 10 years ago for my then Misses, Worked a treat 👍

Hi David. So you could supply studs cable fuse. Inverter is that right. Leave the inverter choice to you. So how much and how do I pay.
 
With a pair of those studs, two pieces of 25mm Cable (batteries to studs) and one of 10mm + fuse holder + fuses and postage, be about £18.
Inverter. ... I would probably go for the cheaper Edecoa one - easiest way to buy is you to get from Amazon direct via that link.

As mentioned, with the thicker cables you would need to make a cutout on the battery box lid to accomodate the extra thickness of the cable.
The remote uses an RJ45 (like a network cable) and they supply a good length so you could fit that just about anywhere within reason to control the inverter.
I'd also suggest a little extension lead so you can plug in the hairdryer easily without lifting the seat. Something like this if you don't already have something handy - https://amzn.to/3gKQ2Sd
(you could of course easily fit a more permanent socket - happy to do that for you if we are in the same place sometime :) )

Cheers

Hi. Ok those bits plus postage. How much how do I pay. I will sort the inverter purchase myself. Cheers Brian
