These twin core water elements can be used on 12, 24 and 48V battery systems to divert surplus power to a water tank. They have a 1 ¼” BSP boss, are 400mm long and are made from stainless steel. Each core is rated for 1kW.
Choose resistance from the drop-down menu.
The power dissipated in a resistor is calculated as follows:
For example a 1 ohm resistor on a 12V battery will dissipate 14x14/1 = 196W because it will reach 14 volts.
Also check that the maximum current draw does not exceed 30 amps or you may overload your SSR.
Current = Power/fully charged battery voltage.
It is unlikely that your thermostat (if any) will be able to work with the DC current.
On DC water elements good practice is to ensure:
Refer to PS MPPT DC water heater installation Guide June 16 for install instructions.
