Head Scratcher - 40A+ draw from the fridge?
Hi Forums, I installed a GoPower IC 3000 which is an inverter, charger and transfer switch combo unit. In testing, I first ran the TV which pulled ~1.5 A. Then I ran the Norcold 2118 refrigerato...

Oh, so it is normal to draw that much? The Norcold site says 6Amps.

Let's do a little math. Norcold says the fridge pulls 6 amps. That is 120v AC. Six amps 120v AC is 720 watts. Now, you are pulling those watts from your battery bank to feed the inverter. To get 720 watts from the 12v battery takes 60 amps of 12v power. Considering the inverter is probably only about 80% efficient, that 60 amps actually becomes about 75 amps.
So, if you are measuring the 12v draw from the batteries and only reading 48 amps being pulled, you are actually doing very good.
The whole point of this is, don't run the fridge on the inverter. If you don't have 120v power to plug in to, run the fridge on gas.
