Confused beginner trying to spec for a kiln.

In the case of lithium batteries, Wh is the combination derived from the nominal voltage of, for LFP cells, 3.2V per cell x the rated Ah of the bank.
Typo, pretty important, but still just a typo.

Using P vs C is a new thing some cell manufacturers are doing, I'm not sure I understand the goal or reason for the change.

P might seem more intuitive than C...
I dunno...


Not really a typo.
The guy keeps adding W and thinking and stating that means the inverter needs ro be larger.
 
That is foreign power. 110V divided by 13.5A is about 8.2 ohms. I have a little water heater which is exactly that resistance.

If the inverter is 125V, 125V divided by 8.2 ohms = 15.2A

125V X 15.2A is 1,900W. Kinda creeps up on ya.

Your results may vary.

I dont know, i think it is just the initial colt box draw from the elements.
Once they get hot, the demand drops.
I bet, since the thing is rated for 1000W, it only draws 13.5A for a few seconds at startup.
 
Most reported numbers here I take with a grain of salt. At 110V, 1000W would be 9 ohms
If that was operated at 122V, then current would be the reported 13.5A for 1600W.
Small changes in voltage create large changes in power.
