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 automatic discharge, inverter 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] The traditional discharge circuit is to directly connect a discharge resistor in parallel with both ends of the energy storage or filter capacitor. When the circuit is disconnected from the power supply, the capacitor consumes the residual charge through the discharge...
