However, the inverters, controllers, and optimizers in existing photovoltaic power generation systems are usually independent, which has many problems in installation, maintenance, and expansion. Traditional designs require complex wiring and coordination, which increases the complexity and cost of the system.

[0003] In addition, in practical applications, photovoltaic systems often face problems such as shadowing, which affects the system's power generation efficiency.

[0004] Therefore, a solar photovoltaic optimizer with compact size and easy installation has become an urgent problem to be solved.

[0008] An inverter-integrated solar photovoltaic optimizer, which integrates an inverter, a controller and an optimizer. The front of the device is an optimizer and a controller module, which are provided with a display, a USB output interface, and controller buttons; the rear of the device is an inverter module, which is provided with a voltage monitoring component, a USB output interface, a type-C output interface and a 220V output interface; the controller is electrically connected to the display and each output interface; the lower part of the device is provided with an MC-4 interface for connecting to a photovoltaic component and an interface in series with a battery, which can support 5V-220V direct voltage output while operating independently and can also support connecting to a battery for energy storage. A high-speed data bus is used inside the module to support fast communication between components. Each module is equipped with a standardized interface to support parallel or series connection of multiple modules to achieve system expansion.

[0009] As an improvement, the integrated module simplifies the installation steps. You only need to fix the module in the installation position and connect the input and output ports. During maintenance, the faulty module can be replaced separately without disassembling the entire system. It supports flexible expansion, and users can increase or decrease the number of modules according to their needs to achieve dynamic adjustment of the system.

[0010] As an improvement, aviation-grade flame-retardant tin foil and aluminum foil are used to fully cover the internal modules and external safety box of the device to optimize data communication within the device and improve the stability and reliability of the device.

The modular design simplifies the installation and maintenance process, reduces the amount of work and maintenance costs. Users can quickly expand the system scale according to demand, which improves the flexibility and adaptability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

After the machine body (1) is powered on, the device can operate independently. The photovoltaic optimizer module (2) monitors and collects real-time data of the working conditions of the photovoltaic panels, so that the device can continuously perform dynamic shadow capture and tracking processing. During the normal operation of the device, the display (3) LCD screen of the photovoltaic optimizer module (2) will continuously display the current product operation status to prevent the user from performing dangerous operations.
