Operation Modes
-
Auto ModeThe ATS continuously monitors the status of Source A (solar power) and Source B (city power). When the main power source suffers power failure, undervoltage or abnormal power supply, the device will automatically switch to the standby power source rapidly. It will switch back to the main power supply automatically once the main source recovers to normal condition.
-
Manual ModeUsers can manually rotate the operating handle to switch between two power sources. Under manual operation, mechanical interlock works to ensure Source A and Source B cannot be energized simultaneously for maximum safety.
