I've read in a few places that the motor will run a bit hotter with a MSW inverter. Therefore I'm planning to run a PSW with our chest fridge and freezer. Heat and motor longevity along with a small living space and I'll be needing all the coolness I can get.
We're running a similar setup to what you pictured Bansil. Been living with it in the sticks and bricks for about 8 months now. They are going with us into the bus.
Fridge runs 202 watts per 24 hours. 34 to 37 degrees F
Freezer runs 546 watts per 24 hours. Minus 1 to 4 degrees F
Running wattage starts around 140 and slowly drops to about 100 before the fridge or freezer shut off again.
Start up is hard to measure with my Kill-A-Watt as the unit shuts off during start up. I'm guessing over 2000 watts.
