This kit comprises of a 12V 300w element, a high current relay and a level sensor to ensure the element is only activated if it is covered by water. 
 
This is a perfect addition if you already have the Bobil Air Xchange set up, but want to add an electric element so that you can use any excess battery power to heat your water. 
 
We also offer the Solaris controller as an option, this is required for voltage sensing to turn the element on and off when it detects that power is available. This isn't needed if you have a Smart Controller.
 
Please note: This is NOT a replacement kit for the Bobil Hybrid kits.
