Why does my EPEVER Tracer3210AN fail to switch to 220V output when the utility charger is disconnected?

Based on the manual for the EPEVER Tracer3210AN, this device is a DC-to-DC MPPT Solar Charge Controller. It is designed to manage power from solar panels to charge batteries and provide power to DC loads. It does not have a built-in 220V AC inverter or an Automatic Transfer Switch (ATS) to handle 220V utility switching.If your system is failing to switch to 220V when the utility charger is removed, the issue likely lies with an external component, such as an Inverter or an Automatic Transfer Switch (ATS), rather than the Tracer3210AN controller itself. Please check the following:Inverter Status: Ensure your inverter is turned on and receiving sufficient DC voltage from the batteries (which the Tracer3210AN is managing).ATS Configuration: If you are using an external transfer switch to swap between utility power and inverter power, check if the switch is stuck or if the sensing wire for the utility power is disconnected.Battery Voltage: Check the Tracer3210AN LCD display. If the battery voltage is too low (Low Voltage Disconnect), your inverter may have shut down to protect the batteries, preventing 220V output.Wiring: Verify that the utility charger and the inverter are correctly integrated into your power system.If you are using a specific EPEVER Inverter/Charger combo (such as the UP-Hi series) instead of just the Tracer3210AN controller, please verify the 'Output Mode' settings in that device's manual.
