Description

technical field [0001] The invention relates to the field of solar air conditioners, in particular to a solar air conditioner control system with charging, discharging and control 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 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 ,...

Problems solved by technology

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

However, in the first type of capacitive self-discharge circuit, if the resistance is too large, the discharge time will be longer, and if the resistance is too small, the loss will be too large; the second type of capacitive self-discharge circuit needs components such as a discharge relay and a discharge relay control circuit. High cost and short service life
