Internal meeting -- How to use marketing tools well
The earliest PV charge controllers were voltage-controlled switches that disconnected the PV array when a certain voltage was reached. When voltage fell to another, lower point, it reconnected the array. These controllers protected the batteries from overcharging, but were unable to provide the three-stage charging regime recommended by battery Ldsolars for longest battery life, since the controller output was either “on” or “off.”
