Compact fridge and inverter
I bought a 4.3 cu ft VissaniHVDR430SE and tried to run it off my 16 year old 750 watt inverter. I do not see a locked rotar amps for the fridge listed anywhere, nor is the surge watts available for t...

I looked at an AIMS 1250 with the bells and whistles including thermal fan for $125, but has very mixed reviews and there is a Whistler 1600 pro with the bells and whistles for sale on Craigs for $70, which also has mixed reviews.
Real cost is going to be $300 to $500
I would tend to agree with smkettner with the junk part.
When it comes to inverters, shopping for a bargain bin price will typically net junk. Less demanding stuff like TVs you can sometimes get away with junk.. But with a fridge compressor it will eat your cheap bargain bin inverters for breakfast and not even think about it.
Cheap inverters typically do not list the LENGTH of surge they can handle.. Why? Well it is because the inverter simply can not handle very long surge times..
A fridge compressor my have a 1A run rating but the start up surge will run about 10A-11A or as much as 1320W!
A 750W inverter typically will have a 1500W surge rating..
See the problem?
The fridge compressor is pretty much using up all the available surge rating..
Some folks have been able to get away with a 800W inverter but to me that is a bit too close and I would recommend at a min of 1000W..
I also would recommend you take a good look at the Tripplite PV1250, it is a beast and it IS designed to handle the high surge currents of a inductive load like a fridge.
Triplite specs INCLUDES the actual surge time it can handle which is more than most inverters give..
The PV1250 can handle 150% the continuous rating for ONE HOUR! and 200% the continuous rating for 10 SECONDS!
Cheap inverters you might get lucky if they can handle a couple of microseconds of surge..
Is the Tripplite cheap in price? No, it is expensive compared to those cheap inverters but it CAN do what you need.
The PV1250 was my first and only choice to run my home fridge conversion..
You can get one from Amazon right now for $244 HERE but if you shop around you might be able to find it a bit cheaper.
