12v 400w hot water element
Versatile usage in heating up water, such as RV’s, boating, camping. Perfect as a dump load for small wind turbines, it can be used to heat water in your water tank or hot water cylinder, also the same as to apply to solar panels.
The 12v 400w water element can be wired directly to solar panels with around 400 watt output to heat the water. It can be connected directly to a charge controllers 12v output but it would be better to get a high current dc relay and power that by the controller and just use the relay as an inline switch between your battery ( bank ) and the element, high current cable and fuses should always be used when dealing with this sort of current, the standard water tank thermostat can be used to switch the element off automatically when the preset temperature is reached vie a relay.
