Provided in the present application are an inverter and a control method therefor, and an energy storage system. When an energy storage battery (400) is depleted and unable to establish a bus voltage for a direct current bus (200), the energy storage battery needs to be charged by means of an external power supply network. Before the external power supply network charges the energy storage battery, an auxiliary power supply circuit (500) is controlled to be activated for a set duration, so as to convert the alternating current voltage of the external power supply network into a direct current voltage, and then convert the direct current voltage into a target direct current voltage, thereby supplying power to the direct current bus to establish the bus voltage; subsequently, a grid-connected control circuit (300) is activated to establish a path from the external power supply network to the energy storage battery, thereby avoiding damage to the inverter when the external power supply network charges the energy storage battery and consequently prolonging the service life of the inverter and improving the reliability of the inverter.

Disclosed are a photovoltaic system and a method for operating the same. A load device and a switching device are connected in series at an output end of the photovoltaic panel. Upon receiving a power supply instruction to start power supply to the electrical equipment, the output power parameter and the output electrical parameter ratio of the photovoltaic panel are determined firstly. Subsequently, the connection status between the photovoltaic panel and the micro-inverter is adjusted in combination with the output power parameter and the output electrical parameter ratio, that is, it is determined whether the micro-inverter gets access to the photovoltaic panel based on the output power parameter and the output electrical parameter ratio. In the above scheme, it can be determined whether to control the photovoltaic panel to access the micro-inverter for operation by analyzing the output of the photovoltaic panel and according to actual output conditions of the photovoltaic panel. Thus, even without knowing specifications of the photovoltaic panel or whether the photovoltaic panel is in daytime or nighttime, access control between the micro-inverter and the photovoltaic panel can still be achieved precisely, thereby effectively improving the access reliability of the photovoltaic panel.
