Claim 4:
5. The photovoltaic air conditioner control method according to claim 4, wherein setting or resetting preset flag bits according to the determination result further comprises:
resetting the frequency reduction flag bit after setting the frequency reduction flag bit, 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;
setting the frequency limitation flag bit 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
resetting the frequency limitation flag bit 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.
