Power inverter for refrigerator; inverter manufacturers

[MailToHere WillBeIgnored]

What size of 12v DC -> 120V AC power inverter would I need to
run a full size refrigerator or freezer, which draws about 3A?

I'm aware of all the general rules, and am seeking an answer
from someone who has actually done it.

One brand of inverter claims a soft-start technology, which
will gradually ramp up the voltage in this case. Does this
really work?

Are there general differences between the different brands?
Are they all really made by one factory in Taiwan?

FYI: the general rules are that such loads momentarily draw 5x
the steady load. Many inverters can supply 2x their rated
power for 1/2 second, since it's a thermal limitation. That
would suggest I need a 750W inverter.

BTW, one company uses misleading model numbers. Their 800
model is good for only 600W continuous.

Thanks.










Thanks.

Sorry I can't answer your question but I will tell you that while a
refrigerator will draw less than 3 amps while *it is running*, at
start up if will draw much more than that possibly in excess of 6 amps
depending on its size.

JFYI

To be on a safe side, you need to know the power consumption when the
compressor is starting.
