Shutdown Procedure

To safely shut down the AES 210HV system and associated inverter, follow the steps below in order:

1. Initiate Rapid Shutdown on the Inverter

   • This immediately turns off the inverter functions and stops charging/discharging operations.

2. Press E-Stop on the AES 210HV Cabinet

   • This isolates the battery internally by opening the HV contactors.

3. Open the PV Disconnect

   • Disconnect the DC input from the solar array to the inverter.

4. Open All AC Disconnects

   • Shut off all AC power sources connected to the system:

   • Open the grid, load, and disconnect any generator AC to isolate the inverter from external power.

   • To disconnect power to the UPS and internal systems, turn off the cabinet auxiliary AC input by opening the HV Box AC breaker.

5. Open the DC Disconnect on the Cabinet’s HV Box

   • Confirm the AES 210HV DC disconnect is in the open position (OFF).

6. Turn Off the Cabinet UPS (Auxiliary Power)

   • Rotate the UPS switch inside the cabinet to the left to cut off power to the Battery Control Unit (BCU) and LYNK II.

7. Verify Complete Shutdown

   • Confirm that all equipment is powered down.

   • Check that no LEDs are illuminated, no fans or pumps are running, and no indicators are active on the inverter, cabinet, LYNK, or internal systems.
