摘要： The disclosure relates to a method, an apparatus and an external protective device (EPD) for power-off monitoring. The power-off monitoring apparatus is used for monitoring and warning the abnormal power-off of EPD, including a power-taking line, a power-taking switch-on module and a warning module. The power-taking line connects the power-off monitoring apparatus to a dedicated power outlet which is not connected to the power supply circuit of EPD; The power-taking switch-on module monitors whether the EPD is abnormally powered off, and turn on a switch to connect with the power-taking line when abnormal power-off is detected, so that the power-off monitoring apparatus can be launched by taking power from the dedicated power outlet; The warning module is used to send warning information when the power-off monitoring apparatus is launched. Through the mutually exclusive power supply design, the disclosure can connect the dedicated power outlet to work when the EPD is abnormally powered off, thus effectively preventing the safety problems caused by powering off the EPD.

摘要： The application provides an inclined assembly structure for a loading rear carrier, which includes a rear carrier body, wherein two support rods inclined and bent to below the rear carrier body are fixed to the positions, close to front and rear side edges, of the bottom of the rear carrier body. According to the inclined assembly structure for the loading rear carrier of the application, when connecting plates are fixedly attached to butt plates, because the connecting plates are inclined relative to the rear carrier body, and a frame is connected to an external body when in actual use, the gravity generated when carrying heavy objects on the rear carrier body acts on contact surfaces of the connecting plates and the butt plates. Because the support rods are also inclined and bent and matched with the inclination of the connecting plates and the butt plates, the borne gravity is decomposed.

摘要： The present application relates to an energy storage inverter battery charge and discharge control method, and a charge and discharge control circuit. By means of configuring a PI control unit and using AC power as a control object to act on a battery-side control circuit on a battery side, a current control loop reference value Ibatref is formulated. By means of adjusting the current control loop reference value Ibatref of the battery-side control circuit, precise control of battery charge and discharge power is achieved, causing battery charge and discharge power to be optimally managed. In addition, the present application can manage battery energy of the energy storage inverter in a variety of application scenarios, so that energy of a photovoltaic unit preferentially meets a household load demand. Electricity is sold to a power grid unit only when there is excess photovoltaic unit energy. If electricity selling is limited, a battery unit is charged instead and excess energy is stored, achieving maximized use of the photovoltaic unit energy. When photovoltaic unit energy is insufficient, the battery unit discharges electricity to meet the demand of the household's own load, so that the electric charge overhead of the user is reduced as much as possible.
