 A low voltage disconnect is used to stop loads from dragging a battery bank below a given voltage (Vlvd).

+One can also **DIY a low voltage disconnect**.
 In theory the simplest way to implement an LVD would be to wire all loads go through the [[electrical:solar:charge_controller#using_load_output|LOAD output]] of the charge controller, and set the controller's [[electrical:solar:charge_controller_setpoints|Vlvd]].  In practice this is rarely done for reasons given in the link above.  It is more common to run a [[electrical:12v:relay|relay]] on the LOAD output, which is triggered ON/OFF by the LVD setting:

 Observe and adjust based on your experience with your own system.
