Description

technical field [0001] The invention relates to the field of solar air conditioning, in particular to a solar air conditioning system with functions of control and power supply lightning protection. 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 lightning protection measures of the controller are not effective, which affects the safety performance of the system; the capacity and self-discharge of multiple single batteries of the battery are inevitably inconsistent, which affects the life of the battery. [0003] At the same time, the traditional solar control circuit adopts the method of battery single power supply and low voltage disconnection. In this way, there will be an infinite loop: if the power supply voltage of the battery is lower than the set voltage of the disconnect function, the sol...
