If you try to set up a dump load for your solar system with an automotive relay, and your system is not 12V, you will likely fail. This is a more robust item that can be used successfully to control the dump load of a 48V system. I use this to control baseboard heaters that dump excess power after my batteries are full (use for example with Outback FM80).
