  "textContent": "Disclosed are a photovoltaic and a charging control method, device and circuit thereof, and a storage medium. The charging control circuit includes: a double-relay circuit and a charging relay circuit, wherein the double-relay circuit is arranged between a grid side circuit and a machine side circuit of the photovoltaic electric appliance; and the charging relay circuit is configured to turn on to realize the gradual charging of a bus capacitor when the double-relay circuit is not turned one. A charging relay circuit is added to an alternating-current power supply side, so that when double relays are not closed, a charging relay can be closed to realize the gradual charging of a bus capacitor.",
