Abstract
The unit control method includes the following steps: detecting a temperature of an inverter module of a current unit according to a first preset period; and controlling a demand capacity of the current unit and a photovoltaic power supplied by the current unit not to be increased in a case where the temperature is not less than a first preset threshold.
Claims18
A unit control method, comprising:
- detecting a temperature of an inverter module of a current unit at a first preset period;
- and
- controlling a demand capacity of the current unit and a photovoltaic power supplied by the current unit not to be increased in a case where the temperature is not less than a first preset threshold, wherein the controlling the demand capacity of the current unit and the photovoltaic power supplied by the current unit not to be increased comprises:
- determining whether the temperature is less than a second preset threshold, wherein the second preset threshold is greater than the first preset threshold;
- controlling the demand capacity of the current unit and the photovoltaic power supplied by the current unit not to be increased in a case where the temperature is less than the second preset threshold;
- and
- distributing a load increment to other units in an operating state except the current unit in a multi-split system in a case where there is the load increment in the multi-split system.
