A pair of 12VDC 6" 600 watt water heater
elements, never used. These are useful for converting a 120VAC water heater
to operate off 12VDC. Or they can be used as diversion loads for diversion charging
regulators that when the regulator
senses a fully charged battery(s) diverts solar
energy to a dummy load.
The pair are only $50 which is less than half price
of currently advertised units.
