Pure Sine Wave Inverter Size

That would depend on the size and how much the fridge draws when the motor starts, probably a 1000w-2000w would do it.

We run a Samsung 320l fridge freezer 24/7 using a 1500/3000w PSW inverter off 4 x 200ah batteries being charged by 600w of solar panels if that is any help.. smile

thanks guys not sure of the size of the fridge motor but certainly the fridge is a lot smaller than 320 liitre - I would say around the 180 litre mark.bus getting fitted with solar, inverter etc in a couple of weeks so good to know in advance so we get the correct size.
cheers debs and graeme

A decent inverter will have plenty of "extra" capacity for the motor start requirement over and above the continuous rating.
Check the wattage rating of the fridge and allow 20% over that.

Our 520L fridge at home draws about 200W, PLUS 375W when defrosting, so watch that.
It would run happily on an 800W continuous rated PSW inverter, maybe even a 600W one.

A bigger consideration will be where the power comes from and how you will store it.

Cheers,
Peter
