Inverter questions
My new trailer will have a 1500 watt pass-through inverter. I wonder if I can run a K-cup coffee maker and a small blender through it. Both are rated at less than 1500 watts - but what about the 2...

Higher voltage beats fat wire.
Twice the voltage, half the current to do the same work. Very true, but that also comes at a cost. The battery bank would have to be configured for a higher combined voltage, but most RVs are 12V.
12V PSW inverters are cheap and very common. 24V and 48V are less common, and typically cost more. I put a 48V inverter in my golf cart, which uses a 48V battery bank. Thin wire by comparison (1500W inverter, using 6 ga). I still have to use a DC-DC converter to take 48V and make 12V for the lighting and accessories.
As my other recent post mentioned the cost of the fat wire is $51 total. Deduct the cost of thinner wire required for a higher voltage inverter.
Now take $352 for the Xantrex PSW 2KW inverter, and compare the cost to a higher voltage inverter. Is there a cost savings?
Higher voltage is more efficient, but not necessarily cheaper or easier.
But different strokes for different folks.
