power transmission

I am thinking of using a heating element as a dumpload

the element is 60 metres from my controller

according to the voltage drop calculater my 10 mm sq cable would drop 10 volts at 50 amps (if my interpretation is correct)

does this mean I could use a 12 volt heating element

I presume you have a 24v supply. If so then loosing 10v would leave you with about 18v at the heater when dumping.

If you have a modest rated 12v heater that will stand 50% overload it will be ok  but that is a lot of overload and I would question whether the heater will last long.

Do you want the heat? if so you are wasting quite a lot of your available heating in cable loss. If it is just convenience and some heat is going to help then fine but I would think carefully about overloading a 12v heater.

Not enough details to help much.

Thanks Flux

yes my system is 24 volts

and at the moment I am dumping a lot of heat after my batteries are charged

I figured I could preheat my water tank instead of dumping
