What's The Advantage of Direct Solar PV Driven Air Conditioner

The actual working voltage of the compressor for photovoltaic direct drive air conditioning varies depending on the unit model and power configuration:

-For single-phase 220V models, the voltage of the photovoltaic string is usually between 200V and 350V.

-The three-phase 380V model generally has a photovoltaic string voltage between 300V and 450V.

The advantages of the photovoltaic direct drive air conditioning compressor are as follows:

-Strong voltage adaptability: Due to the influence of factors such as light intensity and weather on photovoltaic power generation, the output voltage fluctuates. Therefore, photovoltaic direct drive air conditioning compressors can adapt to a wide voltage range, such as 150V-800V.

-DC drive efficiency: By using DC frequency conversion technology, the DC power output from photovoltaic panels can be directly used. Compared with traditional AC air conditioning, it reduces energy loss during the DC-AC-DC conversion process and improves energy utilization efficiency.

-Intelligent power regulation: Through maximum power point tracking (MPPT) technology and intelligent control chips, the compressor can adjust its power and operating frequency in real time according to the supply of photovoltaic power and the actual operating needs of the air conditioner. When the light is strong, the power can be increased to enhance the cooling or heating effect, and when the light is weak, the power can be reduced to maintain basic operation.

-Dual power complementary: It has two power inputs: AC mains power and DC photovoltaic power. When there is sufficient light, the photovoltaic DC power is used first. When there is insufficient light or at night, it automatically switches to mains power supply to ensure continuous and stable operation.

-Low starting current: When the DC variable frequency compressor starts, the required current is relatively small, the impact on the power grid is small, and it can quickly reach the set operating state, achieving rapid cooling or heating.

-Significant energy-saving features: High efficiency during partial load operation, able to automatically adjust the speed according to indoor and outdoor environmental temperature and load changes, enabling the air conditioning system to maintain good energy-saving effects under different operating conditions.
