24v inverter

Deano,

I assume you mean, "do you need 7.5 amps"?

The amperage rating is only the maximum that the inverter is design to output.
Amperage is governed purely by the device plugged into it and yes it will run at lower amps.

If a device is plugged in and attempts to draw more than what the inverter can deliver, (7.5 amps maximum) the inverter will trip out, so that it is not overloaded.

So, providing your fridge doesn't "draw" more than 7.5 amps, the Redarc Inverter should suit your purposes admirably. The current rating (i.e. that which the fridge will draw at full load) should be marked on a compliance plate somewhere on the fridge.

Now, is it really an Inverter you need?
An Inverter converts DC voltage 12vdc or 24vdc input, to 240 volts AC output.
When you say your Fridge is an old 24 volt type, what do you mean.
Will it only run on 24 volt (DC) input. Or does it require 240 volt (AC) input.
Or will it run on either 24 volt DC, or 240 volt AC input.

It is important that you understand what the Fridge requires as input voltage (AC or DC) before you can choose an appropriate solution to run it from your vehicle supply.

Hi sand man, The fridge dose only run on 24v dc. it has no 240 v input. My car is 12v so need something to convert 12v into 24v dc. Any ideas??? Thanks Deano.

Hi deano,
See, DC to DC Convertors

Or Google for "12v dc to 24v dc"

Try these guys www.electroparts.com.au/vc7.htm try these guys
I am going the other way 24-12v 12amp for $82.50

Good luck

If you can't find a cheaper solution you could buy two of these laptop Power supplies - each puts out 24volts at 5 amps. The cost for TWO will be $140.

Hi guys, talked to the 12volt shop in WA and they said that if the fridge draws 4.5 on start up on 12v, it will draw only 2.5 volts on 24v. at this stage I have a cheapest price of 150 dollars for a 7.5 amp unit. I will keep trying tommorrow. Thanks guys I will let you know. Deano
