How many amps a 600 watts pure sine wave inverter drawn from a 12 v battery ? Regards GG thank you

Hi Gerard, the amount of current drawn by an inverter is governed by the load being imposed on it by the 240V device it is powering, thus if we say it is running flat out it will provide just over 2 amps at 240V, and in the process will draw 600W from the battery, this will take 50Amps, plus a bit to make up for the inefficiency of the inverter, so say an extra 10%.
Maximum current draw about 55 amps.

600 watts divided by 12v (nominal) is 50 amps. This will varie as to load and condition of battery. Bill

Bill did you work that out on your finger's....

The rule of thumb when working with inverters is to divide the load drawn by 10 and not 12. This takes into both the power loss in the inverter and also the smaller losses in the cabling (never discount the second loss, the inverter has also got to make up for the loss there.)
A 600 W inverter could draw 60 A running flat chat.

If you would read the post, I changed it 10 mins later.

G/Day mate on stand by they draw about .5-.7 Amps so they can be a drain if you are not charging your batteries Make sure you have a good heavy wire connecting the inverter to the battery. Here is a link to a very good table and info that will help you will see at 40 amps with a 2 mtr cable you need a cable that has a cross section of 8mm This is the cable I use and I solder all jions and use an Anderson plug for any connections. www.rpc.com.au/pdf/Wire_Chart.pdf Cheers The Hats

Hi
I would be throwing THAT ONE away
12% of rated ouput in standby

I have a 2400w inverter that draws about .5A's on standby and a lot less than that if I put it in power save mode..
Can't use Power save mode as it will not switch on, when the fridge kicks in...

Hi Jurgen
A typo??
I suspect the poster did mean 0.5<0.7A

Yeah I agree PeterQ
My inverter is allegedly 2500W and draws 900mA on standby. so 500mA to 700mA sounds about correct.

HI Hats
I did use mymagnify glass in case the was a small Dec point
But you could have just said it was a typo
I have plenty of them
I like to put at least an 0 in front of the dec point [0.7A]
