Claim 3:
4. The photovoltaic air conditioner control method according to claim 3, wherein setting or resetting preset flag bits according to the determination result comprises:
resetting the frequency limitation flag bit and the frequency reduction flag bit 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;
setting the frequency limitation flag bit 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
setting the frequency reduction flag bit 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.
