There are two main types of battery-backed-up, utility-interactive PV systems. The first and oldest is what is called a dc-coupled charging system. As shown in figure 2, the PV array has a nominal voltage of 24 volts or 48 volts and normally operates through a charge controller to charge a battery bank. The battery bank is connected to a
Charge controller: Solar charge controller is an electronic device that manages the DC power from PV panel/arrays going into the battery bank from the solar array. It ensures that the deep cycle batteries are not overcharged during the day. The power does not run backward to the solar panels overnight and drain the batteries. Its design depends on rated current available from
Lithium–ion batteries (Li–ion) have been deployed in a wide range of energy-storage applications, ranging from energy-type batteries of a few kilowatt-hours in residential systems with rooftop photovoltaic arrays to multi-megawatt containerized batteries for the provision of grid ancillary services.

Typically the PV array may only supply energy for 4 to 6 hours per day. Loads obviously can operate 24 hours a day, so the total amount of PV array energy that can be stored in the battery and the capacity of the battery and size of the inverter determine how long the loads can be operated and how many loads can be connected at any one time.
