Claim 1:
2. The photovoltaic air conditioner control method according to claim/wherein performing frequency limitation and frequency reduction control on the photovoltaic air conditioner according to the determination result further comprises:
controlling the compressor of the photovoltaic air conditioner to exit frequency reduction operation after controlling the compressor of the photovoltaic air conditioner to reduce its frequency, if the grid-side inverter module temperature is less than or equal to a fourth temperature threshold and the grid-side current is less than or equal to a fourth current threshold;
controlling the compressor of the photovoltaic air conditioner to operate stably at a current frequency if the grid-side inverter module temperature is greater than or equal to the second temperature threshold and less than the fourth temperature threshold, or the grid-side current is greater than or equal to the second current threshold and less than the fourth current threshold; and
controlling the compressor of the photovoltaic air conditioner to exit frequency limitation operation if the grid-side inverter module temperature is less than or equal to the first temperature threshold and the grid-side current is less than or equal to the first current threshold, wherein:
the first temperature threshold, the second temperature threshold, the fourth temperature threshold and the third temperature threshold increase sequentially, and the first current threshold, the second current threshold, the fourth current threshold and the third current threshold increase sequentially.
