Question: what would happen if it was a 500 watt element for 24V DC?
500 watt 24V DC cartridge heater 1/2 inch NPT
If that fits it would still be worth it. wouldn't blow it up at any point because of too much voltage. If they are all the same thread even a bit bigger like the 800 or 1000 watt one might be worth a try.
I need to take readings still to confirm, but my hunch is that the element receives full panel wattage at the full potential array voltage (18V?) when it is getting diversion current. Does that change the math?
ya it's not as easy as going if you halve the voltage, you 1/4 the power from the rated input. so if it gets 18V you would end up around 1/2 the power rating (just guessing off the top of my head after just waking up and getting ready for a night shift ;) )
