Internal meeting -- How to use marketing tools well

All our staffs in the sales department were together to learn how to use marketing tools well.
We are serious in learning and making better solar charge controllers.

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.”
