Relay Charge ControllersRelay charge controllers were the second type of charge controller to be developed. They are similar in function to the shunt type charge controllers except instead of short circuiting the panel output they open circuit between the solar module and the batteries. These controllers have a set on and off voltage with a hysteresis (difference) usually adjustable by the user. When the batteries hit the high voltage setting the entire electricity source is disconnected until the voltage hits the low voltage setting. This keeps the batteries regulated but the voltage can vary between the on and off settings and is not that consistent. These also can only be used as a solar charge controller (not for use with water power or wind power) . | ||||||||||
