Can you run a Bar Fridge from a 600 w inverter? NO.

My 65w waeco 240v fridge runs perfect off my 1500watt inverter.

start up is around 650watt.

Your 600w inverter should be able to handle peaks of around 1200w for a short time

Spot on 600w only gives a start factor of 7.8 it could be as high as 20 to 30 which means a 1540w to 2300w to start
At a guess your 600w unit may only be 900-1200w intermittent load
A1200-1500w unit may start it but it is'nt good for them , try asking the supplier for specs and the warm start current rating and go from there

What you do is, go to Bunnings and buy a cheap GMC 850w genset, then convert that to Gas as it is cheaper to run, then convert the bar fridge to gas, as that would be cheap to run as well, then you could use that as a two way fridge.

Sorry Jim couldn't help myself. ROTFLMAO.

Cheers Steve.

Yes if the inverter and battery supply voltage are up to the job.

Here are the test pictures of the i-500M

Jim,

I had the same problem. I bought a 1500w Modified Sine Wave with 2500w surge and still had the same result. Since then I have bought a 600w Pure Sine Wave from Jaycar and yep, no joy. In other words don't keep forking out the dollars. So I wonder if there are different qualities of pure sine wave inverters. I've given up on this and am looking for a second hand 3 way fridge.

Hi Jim

I have been through this exercise recently with a smaller bar fridge about 70litre. A friend has the same fridge. We found that my 300 watt modified sine wave invertor would run either fridge. The fridge draws about 55 watts when running and according to a plug in power meter peaks at about 180 watts at startup. We did find however that if the fridge was disconnected from power, it seemed to have some type of reset time and would not restart for 2 minutes. So in short I would have thought that your fridge would operate from your inverter considering it is twice mines capacity. My fridge is a cascade brand and the inverter from dick smith. Hope this helps.

Jim check the DC volts at the inverter when the fridge is turned on to ensure the battery & associated wiring is suppling the required current. I had heaps of problems with a small inverter only to find that undersized wiring caused too much line loss at start up.

Hi Jim,

For a couple of years we quite successfully ran a 180L Fisher & Paykel fridge/freezer from a basic 1000W modified square wave inverter (which is what so-called modified 'sine' wave inverters really are) from time to time. I think the F&P was rated about 120-130W

The inverter was fed by heavy cables about 1m long from two 70Ah VRLA batteries.

Try plugging the fridge into 240ac with an ammeter inline and see what the startup amps are (safety precautions taken). Obviously, if the start up current is greater than your inverter capacity.. move on.
