21.6: DC Circuits Containing Resistors and Capacitors
RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from the initially uncharged capacitor.
Solar Charge Controller 101: A Beginner''s Guide

What happens if you have solar and the power goes out?
Unlike solar without batteries (i.e. a grid-tied solar system), a solar-plus-battery installation keeps your power on by "islanding," or disconnecting itself from the grid when an outage is detected. While the blackout remains in effect, your little solar island will charge the batteries during the day and discharge them at night.
