this is Industrial quality it has a heavy transformer, it handles motor surges with ease, and it doesn't overheat, its designed to operate electric motors

it has been running our residential fridge 24/7 almost 4 yrs now..be 4yrs in Nov

here is the tripplite website about that inverter

X2 on the Tripplite!

This is the same model I decided to use with my home fridge conversion 7 years ago. It is a very robust well designed MSW which uses a old school heavy 60hz transformer in the output stage to boost the 12V AC to 120V AC. This design allows the transformer to absorb the large inductive back EMF which happens when running induction motors in fridge compressors.

Built like a tank and most likely will outlast your RV and then some.

I also make use of the "load sense" feature which turns off the output stage when no 120V demand is detected. I set mine so a 9W load will turn the inverter on so when I open the fridge door the inverter turns on and powers the light bulb, close the door and inverter shuts down..

The Amp/hr savings is substantial using the load sense to the tune of at least 24Ahr per 24 hrs!

I also am using a Haier 10 cu ft fridge, we love it, keeps the food at 34F-36F all day and night (100F temps in the day and 70F at night) unlike the old absorbtion fridge which would be as high as 50F in the day and drop to 20F at night (freezing the milk solid overnight)..

As far as batteries, we are light users but one pair of 6V GC batteries gives us plenty of power to overnight using the furnace and running the fridge..
