 A low voltage disconnect is used to stop loads from dragging a battery bank below a given voltage (Vlvd).
-The simplest way to implement an LVD is to wire all loads go through the LOAD output of the charge controller, and set the controller's Vlvd.  If the controller has no LVD or if the load is heavier than the LOAD output can provide, one may:
