Description

Technical field [0001] The invention relates to the field of solar air-conditioning, in particular to a solar air-conditioning system with charging, control and photovoltaic inverter functions. Background technique [0002] The solar air conditioning system is composed of solar cells, controllers, storage batteries and inverter air conditioners. The existing solar air-conditioning system has the following defects: the controller's lightning protection measures are not effective, which affects the safety performance of the system; the capacity and self-discharge of the multiple single batteries of the battery are inevitably inconsistent, which affects the battery life. [0003] In addition, when there are several consecutive cloudy and rainy days, the power of the battery is not enough to maintain the work of the powered equipment, which will affect the normal operation of the powered equipment. To solve this problem, you can increase the capacity of the battery and solar panels. ,...
