Inverter power drain

Thanks austastar
I have a couple of old computer fans at home so I'll have a play and see if I can work out how to use them.

trouble with computer fans is they wont push nearly as much air as a 240v box fan does.

Also the box fans that have the revolving front are great for moving air to all corners.

I have a honda genny and ac in van, but only run it for a few hrs in late arvo.

Of an evening I run a small inverter (150w) on a box fan with a timer, I usually run it for about 5hrs 10pm to 3am, when it knocks off as its cool by then and everyone well asleep, the timer draws very little.

The following arvo when genny on I charge it up with a 25amp ctek charger for about 3hrs and it is right to go another night.

80% is a very safe margin, I always run mine down to 50-60% and have done for years with no ill effects.

Thanks anglepole
Would run off aux. battery so no worries there.

Thanks Derek
Will run off auxillary battery. As we only plan to camp for one night (2 max) per spot the battery will be recharged by driving the next day.

If it was a 50 w fan the maths do not add up.

P=ExI

p= 12 x 3.1A
p = 37.2 A.

Your fan must have been much lower load than anticipated.

I also have a major issue with you using amps used over a period instead of the industry standard of Amp/Hours. This is extremely unprofessional.

Thanks for your concern.

I used an amp clamp meter not maths.

I try to explain things so the average person can understand, sorry if this upsets you.

NOTE: P=37.2W

LOL this must be a 12 volt thread with all the agro

only thing ill say is I seem to run my 700cca cranking battery too flat to start the diesal in only a matter of a few hours with a dick smith 300 watt inverter running only a computer watching DVDs

this was acertained using no maths or amp meters

Hi get outmore

Replace your battery soon. It is not holding charge.

Derek.

Try using an AGM Deep CYCLE battery instead of a CRANKING battery

You will see the difference in battery performance in first night

No worries on that count Kiwi Kia - it's mounted on the cargo barrier with plenty of breathing space all around it.
