[T2] [VB] cooler/fridge ....

[c.dreike]

David,
I have a modified sine wave inverter, the cheap type. The refrigerator 
doesn't start immediately. It coughs a couple of times as the inverter 
overloads and resets and then starts up. Once running its fine. The 
motor doesn't overheat. I was going to try a larger unit for the start 
up surge but have not gotten there yet. The 400watt unit I have is 
supposed to be good for at least a 600 watt surge. The motor is rated at 
90 watts. Go figure.

Eventually I'll mount the inverter near the battery to minimize the 
voltage drop in the feed wiring. That means running a 115VAC line 
through the bus. Be careful if you do this and make sure that the line 
can't be easily cut. Safety first. You don't want to electrify your bus.
