Claim 7:
8. A photovoltaic air conditioner control apparatus, comprising:
a detection module configured to detect grid-side inverter module temperature and grid-side current of a photovoltaic air conditioner in real time;
a determination module configured to determine an interval in which the grid-side inverter module temperature is located and an interval in which the grid-side current is located; and
a control module configured to perform frequency limitation and frequency reduction control on the photovoltaic air conditioner according to a determination result, comprising:
controlling a compressor of the photovoltaic air conditioner to continue to operate according to a current operating state if the grid-side inverter module temperature is less than or equal to a first temperature threshold and the grid-side current is less than or equal to a first current threshold;
controlling the compressor of the photovoltaic air conditioner to operate stably at a current frequency if the grid-side inverter module temperature and the grid-side current continue to rise, when the grid-side inverter module temperature is greater than or equal to a second temperature threshold and less than a third temperature threshold, or the grid-side current is greater than or equal to a second current threshold and less than a third current threshold; and
controlling the compressor of the photovoltaic air conditioner to reduce its frequency if the grid-side inverter module temperature and the grid-side current continue to rise, when the grid-side inverter module temperature is greater than or equal to the third temperature threshold, or the grid-side current is greater than or equal to the third current threshold.
