Using an Electric Heater as a Dump Load

April 12, 2013

A common question I get asked is “Can I use a standard 120/240 AC heating element or hot water heater element as a DC dump load for my wind turbine/water turbine/solar system?” (Wondering what a dump load is? Click here) The answer is yes but don’t expect it to consume (dump) as much electricity as […]
