ELECTRICAL HAZARD

Only qualified personnel should perform system startup. Ensure all PPE is worn and Lockout/Tagout procedures are followed, where applicable.

Failure to follow these instructions may result in death or serious injury.

Verify Installation

  1. Confirm all AC and DC connections are properly terminated and torqued.

  2. Confirm the Manual Service Disconnects (MSD) are installed in each battery pack.
    MSDs are removed from battery packs during shipping.

  3. Close the door on the battery side of the cabinet.

  4. Close the battery disconnect switch on the High Voltage (HV) box.

  5. Reset the E-stop button.
    The E-stop is engaged during shipping.

Apply Auxiliary AC Power

Perform the following only after completing the above steps.

  1. Supply the 240 Vac auxiliary power to the AES Cabinet and close the AC breaker on the HV box.

  2. Wait for the Thermal Management System (TMS) and Battery Control Unit (BCU) to power up.

If the above procedures are performed out of order, a pre-charge fault will occur, the contactor will not engage, and power from the DC battery is not sent to the inverter.

Power Up the Inverter

  1. Wait for the inverter to power up from either the battery or AC input.

  2. Close the AC disconnect feeding the inverter.

  3. Confirm the inverter recognizes the battery through the LYNK II Gateway via CANbus.

Monitor Initial Conditions

  1. Confirm the State of Charge (SOC) is within operational range.

  2. Verify all system alarms are cleared.

  3. Use the Sol-Ark interface or LYNK Access software to confirm:

    • Battery communication

    • Voltage and current levels

    • Temperature readings

Shutdown Procedure

ELECTRICAL HAZARD

Shutdown must be performed in a controlled environment. Always isolate AC and DC sources before disconnecting any equipment.

Failure to follow these instructions may result in death or serious injury.

  1. Stop Charge/Discharge Operations

    • Use the inverter interface to stop all charge and discharge activity.

    • Open all DC disconnects and AC disconnects on the inverter.

    • Wait until the battery current reads 0 A.

  2. Turn Off the Inverter.

    • Power off the inverter using its built-in switch.

  3. Press the E-Stop button on the AES Cabinet to open the internal contactors.

  4. Open the battery disconnect on the HV box to isolate the battery from the inverter.

  5. Turn off the auxiliary power.

    • Switch off the 240VAC auxiliary supply to the cabinet. Open AC Breaker on HV Box.

    • Wait for the BCU and TMS to fully power down.

  6. Remove Manual Service Disconnects (MSD).

    • Carefully remove all the MSDs from the battery packs to isolate internal DC power from the HV box and system components.

  7. Close and lock all cabinet doors. Apply a warning tag on the door: “De-energized – Maintenance in Progress.”
