Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic inverters, in particular to a photovoltaic energy storage inverter. Background Art

[0002] Photovoltaic inverters are inverters that can convert the variable DC voltage generated by photovoltaic solar panels into AC power at the mains frequency, which can be fed back to the commercial power transmission system or used for off-grid power grids. Photovoltaic inverters are one of the important system balancers in photovoltaic array systems and can be used with general AC-powered equipment. Solar inverters have special functions for photovoltaic arrays, such as maximum power point tracking and islanding protection.

[0003] In traditional photovoltaic inverters, the shunt connector and main connector are both located at the bottom of the inverter. In addition, some inverters are directly installed outdoors, and the connector is easily corroded by rain or sunlight. At the same time, if the connector is placed in a groove, the shunt connector has multiple connection points, which will undoubtedly make it quite inconvenient to connect the shunt connector to the corresponding line. Therefore, photovoltaic energy storage inverters are urgently needed to solve the above problems. Utility Model Content

At the same time, if the connection socket is placed in a groove, the shunt connection socket has multiple connection points, which will undoubtedly lead to quite inconvenient problems when connecting the shunt connection to the corresponding line.

[0005] The utility model provides the following technical solution: a photovoltaic energy storage inverter, comprising an inverter mechanism, wherein the inverter mechanism comprises an inverter body and a main slot opened at the bottom end thereof, and a main connection seat of the inverter body is located in the main slot;

[0006] A shunt mechanism, the shunt mechanism comprises a mounting sleeve with an open bottom end, and the mounting sleeve is embedded and installed at the bottom end of the inverter body, a mounting plate is slidably installed in the mounting sleeve, a shunt connection seat is evenly embedded and installed on the mounting plate, an electric wire is connected to the end of the shunt connection seat, and the end of the electric wire is electrically connected to the inverter body, a threaded sleeve is embedded and installed at the midpoint of the mounting plate, a threaded rod is rotatably sleeved in the threaded sleeve, and the top end of the threaded rod is movably sleeved with the inner wall of the mounting sleeve;

[0007] The wire-winding mechanism is arranged on the inverter body outside the mounting sleeve.

[0008] To implement the above technical solution, an installation sleeve and a main position groove are used to protect the shunt connection seat and the main connection seat respectively. At the same time, the threaded rod and the threaded sleeve can allow the shunt connection seat to move up and down, so as to facilitate its connection with the corresponding branch line. Compared with the existing technology, this device can not only protect the connection seat, but also is relatively simple to install the line, which is convenient for the staff to work.

[0009] Furthermore, the wires inside the inverter body are in a threaded shape.

[0010] The implementation of the above technical solution makes the deformation trajectory of each wire more stable and less likely to be entangled with each other.

[0011] Furthermore, a limiting groove is provided on at least one side of the installation sleeve, a limiting block is slidably installed in the limiting groove, and the limiting block is connected to the installation plate.

[0012] To implement the above technical solution, the limiting groove and the limiting block are used to limit the movement of the shunt connector, so that the movement is more guided.

[0013] Furthermore, the length of the limiting groove is smaller than the groove depth of the installation sleeve, and the difference is at least one centimeter, which is used for folding and placing the wires.

[0014] The above technical solution is implemented to avoid excessive squeezing of the wires by the mounting plate.

[0015] Furthermore, the wire-winding mechanism includes a U-shaped frame, which is connected to the inverter body outside the mounting sleeve. A wire clamping groove is provided on the U-shaped frame, and a notch is provided on one side of the wire clamping groove. The number of the wire clamping groove and the shunt connecting seat are the same, and the mounting position is vertically aligned.

[0016] To implement the above technical solution, the connecting wires can be separated by using the wire clamping groove.

[0017] Furthermore, both sides of the notch of the wire clamping groove are designed to be curved.

[0018] Implementing the above technical solution makes it easy to press the connecting wire into the wire clamping groove from the notch.
