HELIOS ESS Commissioning Checklist
Use this checklist to confirm the correct installation and function of the HELIOS ESS during the commissioning of the complete energy storage system. This checklist is only for the installation and operation of the HELIOS ESS . Further system-level functionality checks and tests must be performed once the full system is interconnected with the HELIOS ESS to complete commissioning.
Battery Installation
PROCEDURE | CHECK |
|---|
Ensure that the battery is securely anchored to the Wall-Mount Bracket. Verify that:
| |
Check the battery cable connections on the inverter.
Verify that: The positive battery cables (RED) are fastened to the correct positive terminal on the inverter and secured using the torque as recommended by the inverter manufacturer. The negative battery cables (BLACK) are fastened to the correct negative terminal on the inverter and secured using the torque as recommended by the inverter manufacturer.
| |
Check the battery cables and connections to the battery.
Verify that: The positive battery cables are connected to the correct positive battery terminals.̔ The negative battery cables are connected to the correct negative battery terminals. Each battery terminal connection is latched in place.
Note: You should not be able to pull off the connector without pressing the release button on the side of the connector. | |
When closed-loop communication with the inverter is set up with HELIOS ESS batteries without the LYNK II Gateway, confirm its termination resistor is connected to COM2 on the last battery in the LYNK Network (even for 1 battery systems).
| |
If applicable, check the Conduit Box.
Verify that: The conduit box, installed between the inverter and battery, is secure and not loose. The cables passing through the conduit box are not rubbing against any sharp edges. The cables are not overly bent or curled as a result of passing through grommets and conduit.
| |
Equipment is bonded as required per the local installation code.
Verify that:
| |
Additional disconnects and overcurrent protection required by the installation code are installed and suitably rated.
Verify that: Overcurrent protection is suitably rated for min 60 Vdc, 300 A per DC output. Disconnect is rated for min 60 Vdc, and for operating under load of 200 A per DC output.
