Help, I have purchased a 400W Remoska for use in our PVC and would like to be able to use it “off grid” using an inverter. The van has two new 120AH batteries which I think will give me enough power, the Remoska only being used for a maximum of 90 minutes (jacket spuds). The essential question is the size and type of inverter required and the cable size from the batteries to the inverter. You don’t get something for nothing- 240v & 400w comes out at around 1.8A so my calculation is that at 12v to feed in enough power for 400w i would need around 35A draw from the batteries. All the inverters I have looked at appear to have much smaller cable than 35A so where am I going wrong in my calculations? Any advice/experience would be greatly appreciate.
