AC watts vs DC watts - solar power question?
Is the formula for calculating watts for DC the same as for AC (Volts x amps = watts)?
I'm trying to figure out the details of a solar system. There is a company selling controllers that are rated for either 10 amps, 20 amps or 30 amps 12/24 volt DC. At 30 amps 12 volt DC you would only be getting 360 watts right?
Yes! you only will be getting 360 watts.
You didn't explain if the 360 watts was input from the PV panel or if that was load.
Either way 360 watts though, so your correct.
Voltage times amperage = wattage =====> AC or DC, it doesn't matter.
