-[[electrical:solar:charge_controller#shunt_controllers|Shunt chargers]] have a charge-and-stop approach where they:+[[electrical:solar:charge_controller#shunt_controllers|Shunt]] (on/off) chargers have a charge-and-stop approach where they:
   - charge to [[electrical:12v:hvd|High Voltage Disconnect]] (Vhvd) and stop   - charge to [[electrical:12v:hvd|High Voltage Disconnect]] (Vhvd) and stop
   - fall in voltage to a High Voltage Reconnect (Vhvr)   - fall in voltage to a High Voltage Reconnect (Vhvr)

 +**This differs from PWM** because PWM can hold an average voltage by cutting power hundreds or thousands of times a second.  If you make a setpoint for 13.6v it will hold 13.6v as long as sun and [[electrical:12v:loads|loads]] cooperate.  A shunt programmed to charge to disconnect at 13.6v and reconnect at 12.7v will average 13.05v.
