The PV power systems are electrically designed in two ways, i.e., system with a utility power grid having no battery backup (Fig. 4.3) and the other system having battery backup as shown in Fig. 4.4. The second type of system is designed to store energy to supply power to the "critical loads" during the utility outage.
