Abstract: Photovoltaic air conditioners can solve functional problems in special power consumption scenarios, such as communication equipment rooms in remote areas, isolated island lighthouses, etc. It can also save electricity costs for household users. By simplifying the design, the expensive special photovoltaic converters and batteries of traditional photovoltaic air conditioners are removed, and the manufacturing cost of photovoltaic air conditioners is effectively reduced. The controller actively adjusts the bus voltage to realise the adaptive distribution of photovoltaic-mains functions, and the maximum power point tracking algorithm is built into the controller, which improves the power generation efficiency of photovoltaic panels. It takes into account the manufacturing cost and use cost of photovoltaic air conditioner, and realises the function of flexible switching between photovoltaic air conditioner mains power and photovoltaic power supply.
