A simple custom made controller for our hot water tanks.
 
The Bobil Simple Controller has:
A temperature sensor allowing you to view the temperature of the water inside your Bobil Electric tank.
Settings to power the 12V electrical element inside the Bobil Electric tank, and adjust the turn on/off voltages, giving you the ability to use excess solar power when your batteries are full to generate free hot water!
 
This controller eliminates the need for the Solaris voltage controller and the dual display. It also has no inputs for any diesel heater controller - for this please see our more complete Bobil Smart Controller.
