This utility model relates to the field of energy storage technology, and in particular to a photovoltaic-storage off-grid device. An off-grid photovoltaic-storage device includes an integrated cabinet housing a battery pack, a PCS module, an STS module, and an EMS module. The STS module is connected to the power grid and the EMS module, and is used to detect the grid status and send a status signal to the EMS module when the grid is de-energized. The EMS module is used to control the PCS module to switch from grid-connected mode to off-grid mode based on the status signal, so that the battery pack can supply power to the load; it is also used to switch the PCS module back to grid-connected mode when the grid is restored.

This invention discloses an open pneumatic control system for cryogenic liquid rocket engines, belonging to the field of liquid rocket engine design. Compared to traditional closed pneumatic control systems, this invention eliminates the valve assembly box and replaces the control solenoid valve with a new type of solenoid valve with anti-backflow function, and replaces the pneumatic valve with an anti-backflow pneumatic valve. Eliminating the valve box also eliminates the need for the valve box cable, requiring only one control cable, reducing electrical interfaces and improving the reliability of electrical products. In the original closed system, fault isolation between solenoid valves was not possible; this invention, by eliminating the valve box, eliminates mutual interference between controlled valves, achieving fault isolation. The solenoid valve layout of this invention is more flexible, has higher structural reliability, facilitates fault isolation, improves functional reliability, and simultaneously reduces engine weight.
