Description

Technical Field

[0001] This utility model relates to the field of inverter power supply technology, and in particular to a smart switching solar inverter power supply. Background Technology

[0002] An inverter power supply typically includes an inverter and a battery. The inverter converts the direct current (DC) power from the battery into alternating current (AC) power of a certain voltage to meet the operating requirements of electrical equipment.

[0003] To meet the needs of long-term outdoor operation, solar panels can be used to charge the batteries in the inverter power supply. For example, utility model patent application number 2013205861807 discloses an intelligent solar inverter power supply, which meets the requirements of users in the wild or in areas without electricity. However, ordinary inverter power supplies usually only have one battery, and when the battery experiences problems such as overload or overheating, the power supply often needs to be shut down, making it impossible to continuously power the equipment. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent switching solar inverter power supply that can detect and switch between multiple batteries to ensure stable operation of electrical equipment.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A smart switching solar inverter includes: a solar panel, a smart charge / discharge controller, a battery pack, a switching circuit, and an inverter. The battery pack contains multiple independent batteries. The smart charge / discharge controller is connected between the solar panel and the battery pack to detect and control the charge / discharge of each battery. The switching circuit is connected between the battery pack and the inverter. The smart charge / discharge controller is connected to the switching circuit and selects the normally operating battery to power the inverter.

[0007] The switching circuit includes multiple switches, each corresponding to a battery.

[0008] The intelligent charging and discharging controller includes an inverter circuit, a control circuit, and a detection circuit.

[0009] The battery is equipped with a temperature sensor, which is connected to a detection circuit to transmit signals.

[0010] The number of batteries is at least two.

[0011] The inverter is connected to the charging and discharging intelligent controller.

[0012] The beneficial effects of this utility model are as follows: A smart switching solar inverter power supply is specially designed with multiple independent batteries. The batteries can be detected in real time through a detection circuit. When problems such as over-discharge, overload, and abnormal temperature occur, the switch corresponding to the problematic battery is turned off, and the switch corresponding to other normal batteries is turned on, realizing intelligent switching and ensuring the stable operation of electrical equipment. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0014] The following is combined Figure 1 The technical solution of this utility model will be further illustrated through specific embodiments.

[0015] A smart switching solar inverter power supply includes: a solar panel, a charge / discharge intelligent controller, a battery pack, a switching circuit, and an inverter. The battery pack contains multiple independent batteries, such as... Figure 1 The first battery, the second battery, ... the nth battery are mentioned. In this embodiment, the number of batteries is at least two to meet the basic switching function, ensure the stable operation of the electrical equipment, and reduce costs.

[0016] A smart charge / discharge controller is connected between the solar panel and the battery pack. In this embodiment, the smart charge / discharge controller includes an inverter circuit, a control circuit, and a detection circuit to perform individual detection and charge / discharge control of the batteries. The solar panel charges the batteries in the non-operating state one by one without affecting the normal operation of the batteries in the operating state.

[0017] A temperature sensor is installed on the battery, which is connected to a detection circuit to send signals. The detection circuit can perform real-time detection of the battery. When problems such as over-discharge, overload, and abnormal temperature occur, the discharge of the problematic battery needs to be paused. After the problematic battery cools down, it can be automatically tested. If it passes the test, it can be used again, which has a high degree of automation.

[0018] like Figure 1 As shown, the switching circuit is connected between the battery pack and the inverter. In this embodiment, the switching circuit includes multiple switches that correspond one-to-one with the batteries, which facilitates turning off the switch corresponding to the problematic battery to pause the discharge of the problematic battery, and turning on the switch corresponding to the normal battery to realize power switching and continuously meet the stable operation of the electrical equipment.

[0019] To improve automation, the intelligent charging and discharging controller is connected to the switching circuit to automatically shut off the switch corresponding to the faulty battery and select the normally functioning battery to power the inverter. No manual operation is required, ensuring high safety.

[0020] Furthermore, the inverter is connected to a charging and discharging intelligent controller, which normally keeps the switching circuit open to reduce energy consumption and improve safety. When the inverter needs power, it sends a signal to the charging and discharging intelligent controller. The controller then automatically activates the switch corresponding to the normal battery based on the battery's self-test, thus meeting the inverter's power requirements.

[0021] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
