Example Embodiment

[0017] The present invention will be further described below with reference to the drawings and embodiments.
[0018] See figure 1 , The inverter air conditioner with solar battery includes solar battery 1, inverter air conditioner 6, solar power supply controller 2 connected between solar battery 1 and inverter air conditioner 6, and mains 5, inverter air conditioner 6 includes AC/DC rectifier 8 And the DC inverter air conditioner circuit 7, the solar power supply controller 2 includes a DC/high voltage DC inverter 3 and a maximum power tracker 4; the maximum power tracker monitors the output power of the solar cell 1 and controls the DC/high voltage DC inverter 3 The low-voltage direct current output from the solar cell 1 is converted into high-voltage direct current, and it is directly supplied to the circuit of the direct current inverter air conditioner. Low voltage direct current is 15V~36V.
[0019] The mains power 5 passes through the AC/DC rectifier 8 and is connected in parallel with the solar power supply controller 2 to supply power to the DC inverter air conditioner circuit 7. The maximum power tracker 4 built in the solar power supply controller 2 detects the voltage and current output by the solar battery 1, and controls the converted output power of the DC/high-voltage DC inverter 3 through a dedicated algorithm, and supplies the DC inverter air conditioner in the inverter air conditioner 6 Circuit 7 is used.
[0020] The solar cell 1 in this embodiment uses an ordinary solar cell. A solar cell panel usually outputs 24-30V, 0-240W, and multiple panels can be used in parallel.
[0021] The inverter air conditioner 6 in this embodiment has two power input ports. The output port of the solar power supply controller 2 is connected to the first input port of the inverter air conditioner 6, and the AC mains 5 is connected to the second input port of the inverter air conditioner 6. . The first channel is directly connected to the DC inverter air conditioner circuit 7 in the inverter air conditioner, and the second channel is connected to the DC inverter air conditioner circuit 7 after connecting an AC/DC rectifier 8. Usually when the solar battery 1 provides sufficient power, the DC inverter air conditioner circuit 7 in the inverter air conditioner 6 is powered by the solar power supply controller 2. When the solar battery 1 provides insufficient power, the insufficient part is provided by the mains 5 to meet The DC inverter air conditioner circuit in the inverter air conditioner 6 is used. In order to make full use of the electricity generated by solar energy and reduce the consumption of city electricity.
