Grid-connected air conditioner with solar cell power generation system and control method

摘要

In an air conditioner connected to a solar cell power generation system and a commercial AC power supply separately, a solar radiation sensor detects solar radiation to calculate a generation current, and a voltage detection means detects a generation voltage to calculate generation power using the generation current and the generation voltage. After calculating the load power from the load current detected by the current transformer and the voltage of the commercial AC power supply, the air conditioner is automatically operated by the power generated by the solar cell power generation system even in the off mode according to the generated power and the load power.
