so if I have two (2) 4500 watt 240 volt elements in series, then I get 120 volts across each, and roughly 1000 watts of heating from each? if so what would be the amps draw? sorry Ohms got my head messed up at the moment.

conversely, if I had two (2) 4500 240 volt elements in parallel then i get 240 volts across each and roughly 9000 watts of heating?

how does a normal US water heater wire the elements? i know they have separate thermostats but do they end up in parallel using 9000 watts, or do they end up in series using about 2000 watts?

the reason i ask is my soon to be dedicated to water heating inverter offers 5000 watts at 230 volts, its one of the euro type sigineer units. if one element is 4500 watts that maxes out the inverter with one element would it be better to use two and half (or quarter?) the heat output?

guessing it might be better to use just one.
