Problems solved by technology

When there is a problem with the inverter at the input or output end, it will cause the energy input device at the input end to fail to supply power to the system or the output voltage at the output port is abnormal. Moreover, when the DC bus fails or the energy storage module has a problem, it will cause the whole system to be paralyzed
