+**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.
 These setpoints may or may not be user-configurable.

 AGM batteries are kept healthy by:

+A [[http://amzn.to/2gEtVwL|battery waterer]] can make the job easier, and does not require one to judge water level visually.  The water "bloops" as it fills and stops blooping when the water is at the correct level.
 Batteries that are older, in poorer health, or are charged at higher voltages will be "thirstier".  Check water levels 1x/month until you know how they behave.
