상황
A small DC wind turbine charges a 12V battery through a fuse and blocking diode; a low-voltage disconnect protects the battery and a timer switches a remote street lamp.

01
Include a blocking diode to prevent reverse current from the battery to the turbine.
02
Use a normally closed SPST switch as the low-voltage disconnect so the load drops out on low battery voltage.
03
Model the timer as an SPST switch in series with the lamp for remote on/off control.
When designing or documenting small off-grid wind/battery DC systems that need battery protection and timed lighting loads.
