In cloudy or lightless weather, the storage battery pack supplies power to DC loads through the solar charge and discharge controller. The off-grid inverter is one of the key components used in off-grid solar photovoltaic power generation systems. Its function is to convert the direct current generated by solar photovoltaic panels into alternating current. Since the off-grid inverter needs to work in coordination with the battery energy storage system, it is necessary to consider installing the inverter at a position closer to the battery energy storage system to reduce the loss of transmission lines.

[0003] The off-grid inverter is installed on a solar rack, and the wires can be restricted by a cross rack. The transmission wires are led out through the off-grid inverter, and their lower ends are often in an exposed state, which not only easily affects the use of the off-grid inverter, but also the wind acts on the wire body, causing a swinging phenomenon, which easily affects the output of the transmission line and reduces the use effect of the photovoltaic power generation device.

A wire body control plate for controlling the position of the wire body is arranged on one side of the side protection plate.

[0006] Wherein, a bottom mounting plate is fixedly connected to the bottom of the front protection plate, and the bottom mounting plate is fixedly connected to the cross bar.
