solar controller comprises a charging circuit, a
control circuit, a
lightning protection circuit and a discharging circuit, the variable frequency air conditioner comprises an inversion circuit and a compressor, the charging circuit comprises an eleventh
resistor, a twelfth
resistor, a thirteenth
resistor, a fourteenth resistor, a fifteenth resistor, a sixteenth resistor, a seventeenth resistor, an eleventh
capacitor, a twelfth
capacitor, a thirteenth
metal oxide semiconductor (MOS)
transistor and a fourteenth MOS
transistor, and the discharging circuit comprises a forty-first switch, a forty-first
relay, a forty-first resistor, a forty-second resistor, a forty-third resistor, a forty-fourth resistor, a forty-fifth
discharge resistor and a forty-third
electrolytic capacitor. By the solar air conditioner
system,
lightning can be effectively prevented, the safety performance of the system is improved, the activity of the storage battery can also be ensured during charging of the storage battery, the service lifetime of the storage battery can be prolonged, the charging efficiency of the storage battery can be improved, the power utilization time of the storage battery is prolonged, the solar air conditioner system has relatively high self-starting capability, an endless loop state is prevented, the
discharge time can be greatly shortened, and the
energy consumption of the system is saved.
