My question is the conversion from AC watts to DC watts this simple?
AMPS multiplied by VOLTS = WATTS
WATTS divided by VOLTS = AMPS
Then the watts are converted to amps in the other voltage.
If and inverter is needed I assume the crock pot 100 watts is for the AC side. For AC; 100 WATTS divided by 110 VOLTS is .9 AMPS AC
Since the power supply is a DC Battery (or Solar panel) feeding an inverter - 100 watts DC divided by 12 VOLTS = 8.3 AMPS DC plus the losses of the inverter.
While most inexpensive inverters (modified sine and pure sine) tout 90% efficiency some reviews I have read say they are more like 65% efficient. Which would mean the DC supply might need to supply the inverter with 9.2 amps for 90% efficiency and 12.7 AMPS for 65% efficiency
I am not sure about any of the above – but this my understanding of how this works. I might be off in the trees looking for coconuts on this. I welcome enlightenment.
