[0099] In the prior art, the prior art of high current and high voltage photovoltaic panels generally adopts the method of adding a P-channel field effect transistor at the front end to prevent the solar panel from being reversely connected, and adding a P-channel field effect transistor to prevent overvoltage, or adopting a front-end rectifier diode to prevent the solar panel from being reversely connected;

[0100] However, the high-current and high-voltage P-channel is expensive and difficult to select. The P-channel is only suitable for low-current and low-voltage photovoltaic panel charging, and is not suitable for the application and promotion of high-current and high-voltage photovoltaic charging products.

[0101] In addition, when a rectifier diode is added, the diode voltage drop is high and the loss is serious.

[0102] The photovoltaic panel circuit of the prior art is as follows Figure 7 and Figure 8 As shown, Figure 7 When the photovoltaic is connected to Q5 normally, the back-end BUCK / BOOST is turned on and works. When the photovoltaic is reversely connected, Q5 is turned off and the BUCK / BOOST does not work. However, this circuit is not suitable for high-current photovoltaic controllers. The cost of P-channel field effect tubes is high, and the higher the current, the higher the cost. In addition, the PV+ voltage exceeds the withstand voltage of Q5, which will cause Q5 to burn out due to overvoltage, and even burn out the H-bridge MOS of the back-end BUCK / BOOST.

[0103] Figure 8 In this circuit, PV can be connected in both positive and negative directions, but the rectifier bridge has a large voltage drop loss and is not suitable for high current applications.

[0104] The photovoltaic panel circuit of the present invention is as follows Figure 6 As shown, when PV is connected normally, Q19 body diode is turned on, Q19 provides power for the control MCU circuit, and the controller calculates the PV voltage through R25, R28, and R32 voltage divider. If the PV voltage exceeds the threshold voltage, the relay does not operate, and the physically isolated back-end BUCK / BOOST circuit is not damaged by high voltage. When PV is reversely connected, Q19 is cut off, and it cannot provide power for the control MCU circuit. The relay will not operate, and the BUCK / BOOST circuit will not work either, so that the photovoltaic panel circuit has the performance of anti-reverse connection and anti-overvoltage operation, and the relay has a wide selection and strong overcurrent capability, which is more suitable for large-current PV charging solutions.

[0105] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
