[0015] Compared with the closest existing technology, the present invention has the following beneficial effects:

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Figure 1 This diagram shows the overall structure of the integrated solar inverter control unit of this utility model; Figure 2 This diagram shows the internal structure of the integrated solar inverter control unit of this utility model; Figure 3 This diagram shows the bottom of the integrated solar inverter control unit of this utility model; combined with Figure 1-3 As shown, this utility model provides a solar inverter control integrated machine, which includes: a housing 1, multiple fans 2, multiple heat sinks 3, an external unit 4, a first circuit unit 5, and a second circuit unit 6.

[0024] The housing 1 is divided into a first area and a second area. The first circuit unit 5, the second circuit unit 6, the fan 2 and the heat sink 3 are all located in the first area, and the external unit 4 is located in the second area. A partition 8 is provided between the first area and the second area. The partition 8 has multiple through holes. The fan 2 is spaced at the through holes. The housing 1 has several air guide holes 9 on the first side wall 101 and the second side wall 102 opposite to each other in the first area. The heat sink 3 is spaced between the first side wall 101 and the second side wall 102, and the heat sink 3 and the fan 2 are arranged in a one-to-one correspondence, so that the fan 2, the heat sink 3 and the air guide holes 9 form an exhaust channel.

[0025] The first circuit unit 5 is located at the bottom of the heat sink 3, and the top of the heat sink 3 is provided with multiple spaced support pillars 7. The second circuit unit 6 is mounted on the support pillars 7. The housing 1 is provided with a photovoltaic input interface and a load output interface. The photovoltaic input interface, the external unit 4, the first circuit unit 5 and the load output interface are electrically connected in sequence. The second circuit unit 6 and the first circuit unit 5 are electrically connected.

[0026] Specifically, the external unit 4 is a circuit board integrated with various components, used to connect to devices connected through external interfaces and to connect to the internal first circuit unit 5.

[0027] The heat sink 3 is fixedly installed on top of the first circuit unit 5. The air generated by the fan 2 is blown onto the cabinet 1 through the airflow channel of the heat sink 3 and spreads to both sides of the cabinet 1. Then, the heat inside the all-in-one machine is guided to the outside of the all-in-one machine through the airflow holes 9 on the side walls of the cabinet 1, so as to achieve the cooling effect more quickly. When the power of the first circuit unit 5 is large, two or three heat sinks 3 are installed on the top of the first circuit unit 5, and two or three fans 2 are set opposite to each other to increase the wind speed and wind force, and continuously cool the inside of the cabinet 1. At the same time, the first circuit unit 5 and the second circuit unit 6 are separated by the support column 7 to form a flow space for air, thereby increasing the heat dissipation effect.

[0028] Furthermore, two or three heat sinks 3 are installed on the top of the first circuit unit 5, and a fan 2 is installed at the position of each heat sink 3. The fans 2 are spaced apart on the partition 8, that is, all fans 2 are located on the same side of the first area. When the power of the first circuit unit 5 increases, the fans 2 work with the heat sinks 3 to accelerate the heat dissipation speed, so as to prevent the temperature from rising when the power of the first circuit unit 5 increases, which could cause damage to the components in the solar inverter control unit due to high temperature. When the number of external batteries is large, the number of heat sinks 3 and fans 2 can be increased accordingly.

[0029] In one embodiment, the housing 1 is also provided with a photovoltaic input port and a photovoltaic indicator light for indicating the connection status of the photovoltaic input port.

[0030] Specifically, by setting up a photovoltaic input port, the photovoltaic panel connects to an external battery through the photovoltaic input port to continuously store power for the rechargeable battery, and the photovoltaic output status is indicated by a photovoltaic indicator light. When the photovoltaic input port is in the connected state, the photovoltaic indicator light lights up, making the status visible. The photovoltaic indicator light provides timely feedback on the photovoltaic connection status to avoid misjudgment. Conversely, when the indicator light is off, the problem can be quickly located and resolved.

[0031] Several guide holes 9 are arranged in an array on the first sidewall 101 or the second sidewall 102.

[0032] In this scheme, when the power of the solar inverter control unit is at its maximum, the temperature of the solar inverter control unit increases accordingly. When multiple fans 2 inside the housing 1 operate simultaneously, air guide holes 9 are needed to guide the airflow. The arrangement of several air guide holes 9 in an array can maximize the airflow inside the housing 1, thereby discharging it to the outside of the housing 1.

[0033] Heat sink 3 is a heat sink with multiple parallel stacked fins, and the height of heat sink 3 is 0.3-0.5 times the height of fan 2.

[0034] Specifically, the air from fan 2 can be dispersed to different locations around the heat sink 3 along the gap between adjacent heat sinks and finally discharged to the outside of the housing 1 through the air guide hole 9, thereby uniformly dissipating heat to the first circuit unit 5 and improving heat dissipation efficiency.

[0035] Furthermore, the height of the heat sink 3 is set to 0.3-0.5 times the height of the fan 2. This allows the airflow from the bottom of the fan 2's exhaust surface to blow directly onto the first circuit unit 5 located at the bottom, thus specifically cooling the first circuit unit 5. Meanwhile, the airflow from the top of the fan 2's exhaust surface blows directly onto the second circuit unit 6, which is at approximately the same height, thus specifically cooling the second circuit unit 6. The airflow from the middle of the fan 2's exhaust surface can be mostly dispersed to various areas of the first region through the heat sink 3, accelerating airflow and achieving circulation, thereby improving heat dissipation efficiency.

[0036] The box 1 has several flow guide holes 9 on multiple side walls in the second region.

[0037] In this scheme, since the first region and the second region are connected and a partition 8 is provided with a through hole, the fan 2 is located at the through hole. The second region is provided with an external unit 4. In order to prevent the external unit 4 from being damaged due to excessive temperature, several air guide holes 9 are provided on all surfaces except the contact surface between the second region and the first region to increase the heat dissipation capacity of the second region.

[0038] The first circuit unit 5 includes a charger, and the housing 1 is also equipped with an AC power interface, which the charger is connected to.

[0039] Specifically, it features seamless switching between hybrid power supplies, allowing the AC power to replenish the external battery via the charger, ensuring battery life on cloudy or rainy days. It also supports AC power priority or solar power priority modes, and the charger is compatible with different AC power specifications, such as 10V or 20V, making it suitable for deployment in multiple regions.

[0040] The second circuit unit 6 includes a display and a temperature protection device and an overload protection device electrically connected to the display, respectively, to indicate excessive temperature or overload through flashing of the display.

[0041] Specifically, an active early warning mechanism is provided. When the temperature is too high, the display 7 will flash to indicate this, preventing thermal damage to components. The display 7 will also show an overload alarm to remind users to reduce the load or increase capacity, thus avoiding repeated system restarts.

[0042] The housing 1 also includes an external battery interface for connecting to an external battery, and the external battery interface is connected to the external unit 4.

[0043] In this solution, an external battery interface is provided for connecting an external battery. The external battery may include multiple sets of rechargeable batteries connected in sequence. The external battery can be connected in parallel to the solar inverter control unit to supply power to the load according to the power demand. At the same time, the power generated by the mains power or photovoltaic panel can also be stored in the external battery through the external unit 4, so that it can be used in emergencies when power is tight.

[0044] A bypass circuit breaker is also provided in the second area of ​​the enclosure 1. The bypass circuit breaker is connected to the external unit 4 to protect the external battery or photovoltaic panel.

[0045] When the bypass circuit breaker is closed, any one of the mains power, photovoltaic panel or external battery, external unit 4, load output interface and load can form a circuit, so that the mains power, photovoltaic panel or external battery can directly power the load, bypassing the inverter link, avoiding the paralysis of the whole system due to inverter failure. The bypass circuit breaker has overload protection function to prevent the load short circuit from affecting the external battery or photovoltaic panel.

[0046] The solar inverter control unit also includes a cable tray 10 and connecting wires. The cable tray 10 is disposed in the through hole of the partition 8. The first circuit unit 5 and the external unit 4 are electrically connected by connecting wires, which are installed inside the cable tray 10.

[0047] In this solution, since there are many connecting lines between the first circuit unit 5 and the external unit 4, the cable management board 10 is needed to solve the problem of messy connecting lines. Messy connecting lines can also cause the temperature to rise, which can easily damage the internal components of the all-in-one machine. Therefore, the cable management board 10 can better solve the problem of messy connecting lines.

[0048] The enclosure 1 is also equipped with a wireless network interface.

[0049] Specifically, it can connect to remote devices via a wireless network interface, such as a cloud platform, to monitor power generation and perform remote fault diagnosis.

[0050] The above are merely embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model shall be included within the scope of the claims of this utility model pending approval.
