Description

technical field [0001] The invention relates to the field of solar energy, in particular to a solar air conditioning control system. 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] In addition, when there are several consecutive 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, the capacity of the battery and solar panels can be increased , but the cost will increase substantially. [0004] At th...

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 solar control circuit will be disconnected, and the solar control circuit itself cannot recover automatically, because the solar control circuit can only When it is high enough to work, the solar energy can charge the battery with the output light energy through the solar control circuit. After the solar controller is disconnected, even if the solar output has electricity, but the battery voltage is not enough, the solar controller is disconnected at low voltage, so this part of the electric energy Can not be charged into the battery, because the solar energy cannot be charged to the battery, so the battery voltage will not rise, and the solar controller will not restart
