[0002] Inverters are core devices that convert direct current (DC) into alternating current (AC) and are widely used in photovoltaic power generation, energy storage systems, and emergency power supplies.

[0003] Currently, in traditional photovoltaic systems, the photovoltaic controller and inverter are usually independent devices, requiring complex wiring to achieve functional coordination. This separate design results in a large system size, high installation and maintenance costs, and energy conversion efficiency losses. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 As shown, one embodiment of this utility model includes a housing with a display screen on top and a power transmission interface on the side. The power transmission interface includes an AC power input interface, a solar panel voltage input interface, a battery DC power input / output interface, and an AC power output interface. The AC power input interface is connected to AC power. The solar panel voltage input interface is connected to a photovoltaic panel array. The battery DC power input interface is connected to a battery pack.

[0021] Among them, such as Figure 2As shown, the box contains a voltage regulator, an automatic transfer switch, a solar controller, and a charger / inverter; the voltage regulator is connected to the automatic transfer switch and the AC power input interface; the solar controller is connected to the solar panel voltage input interface, the charger / inverter, and the battery DC power input / output interface; the charger / inverter is connected to the automatic transfer switch and the battery DC power input / output interface, and the automatic transfer switch is connected to the AC power output interface.

[0022] The box also contains a cooling fan.

[0031]

[0032] This utility model features a sine wave inverter with mains power complementarity and mains power backup charging function. The inverter converts the DC power provided by the battery into AC power to supply the load. It also has a UPS automatic switching function and three working modes: DC main power (solar main power, mains backup), AC main power (mains main power, solar backup), and pure solar power.

[0033] 1. DC Main Supply: Under normal conditions with sunlight, the solar panel charges the battery via the integrated inverter / control unit. When sunlight is insufficient, the unit automatically switches to AC power to directly supply the load, while the built-in AC charger also recharges the battery pack. This operating mode has two control methods: ① Solar power continuously charges the battery: The battery is only used when it is fully charged by either solar power or AC power. Upon power-on, the battery status is immediately checked. If not fully charged, AC power is used for supplementary charging. Once fully charged, the system immediately switches back to battery power until the battery level is low, then switches back to AC power for auxiliary charging. (This method helps protect the battery.) ② Solar power continuously charges the battery: Whenever the battery voltage is detected to be above a specified value, the battery provides power. When the battery level is low, the system switches to AC power for auxiliary charging. (This method maximizes the utilization of solar energy.)

[0034] 2. AC main power supply: The load is normally powered by the mains power, and the solar power generation charges the battery through the integrated control and inverter. When the mains power fails or is abnormal (or is manually turned off), it is converted into pure sine wave power output by the battery inverter.

[0035] 3. Pure solar power supply: Normally, solar energy charges the battery. The user installs a switch at the output load end. When electricity is needed, the switch is turned on, and the battery outputs pure sine wave power to the load through the integrated control and inverter.

[0036] Before operation, the wiring sequence of this utility model is as follows:

[0037] 1. First connect the positive and negative terminals of each battery in the battery pack;

[0038] 2. Connect the positive and negative terminals of the battery's DC power input interface;

[0039] 3. Finally, connect the positive and negative terminals of the solar panel.

[0040] For the installation of this utility model, the following should be noted:

[0041] 1. Do not install the inverter on flammable building materials;

[0042] 2. Install on a solid surface;

[0043] 3. Install the inverter at eye level so that the LCD display can be read at any time;

[0044] 4. To allow for airflow and heat dissipation, please leave a gap of approximately 20 cm at the back and approximately 50 cm at the top and bottom of the device;

[0045] 5. The ambient temperature should be between 0°C and 55°C to ensure optimal operation;

[0046] 6. It is recommended to install it vertically on the wall;

[0047] 7. Ensure that other objects and surfaces are as shown in the diagram to guarantee sufficient heat dissipation and enough space to remove the wiring.
