1.1 Commissioning Prerequisites
The following steps describe the Commissioning process that Tesla Industrial Storage Support will follow.
Tesla may perform this work either on site or remotely at the discretion of the Tesla representative and in
accordance with any site-specific commissioning plan. Tesla will perform Commissioning at Tesla's earliest
convenience, unless the Customer has indicated a necessary scheduled time.
The following conditions must be met before commissioning can begin:
Pre-Commision Step Completed
(Yes/No)
The Construction Checklist has been fully completed, sent back to Tesla, and approved by
Tesla.
Megapack is ready to be energized:
• Trip terminals are open or closed as appropriate
• Remote shut down terminals are closed.
• Close permissive terminals are closed.
• Key is on
AC distribution to the terminals of all Tesla Megapacks must be complete and grid power
available. Exemptions to this may be made at the discretion of the Tesla Project Engineer
following a review of the current site conditions
Energize the Tesla Site Controller, all meters (Site, Battery, PV), and networking.
Tesla requires an onsite presence that is able to perform the following work:
• Operate any circuit breakers
• Measure circuit voltages
• Debug and resolve any networking connection issues
• Debug and resolve any meter connection issues
• Debug and resolve power connection issues
Charge and Discharge limits are identified in the Construction Checklist.
Stable internet connection to Tesla/Internet from the Tesla Site Controller
Internet access for Tesla personnel onsite, if applicable

1.2 Sample Commissioning Activity Overview
Reach out to your Tesla Project Engineer for a Commissioning Timeline. Below is a list of specific activities
that take a minimum of 8 hours to complete on a single Megapack site.
• Confirm communication to the Tesla Site Controller: Tesla remotely accesses the Tesla Site Controller
and confirms its communication to the Tesla Servers.
• SCADA communications check: Tesla confirms communications from the Tesla Site Controller to any
meters or other SCADA equipment present on the network as well as to the Megapacks. At this stage,
Tesla requires power to all devices.
• Tesla internal system communication check: Tesla performs an initial communication check to each
component of the Megapack system from the Tesla Site Controller.
• Firmware Update: Tesla performs an initial firmware update of the system. This update also involves
loading the required Grid Codes. Onsite and Controls power must be maintained for the duration of
the update; interruption of power may require personnel to manually update the firmware of every
component in the system, which extends the commissioning timeline. The Tesla system does not
charge or discharge during the Firmware Update.
• DC Self-test: Tesla performs a DC Self-test. The DC Self-test energizes the system's DC bus and tests
the internal components, namely the thermal and controls subsystems. The system does not charge or
discharge during a DC Self-test, but Onsite and Controls power are maintained for the duration of the
update. Fans and other thermal subsystems operate during the test. Tesla may re-run the DC Self-test
multiple times to confirm the system's operation.
• AC Self-test: Tesla performs an AC Self-test which energizes the system's DC bus and relies on grid
voltage. Main component coverage are the power electronics. This test will place a parasitic load of
<20kW on the grid AC connection.
• Grid Interactive Functionality: If applicable and as determined by the sales contract, Tesla will perform
Grid Interactive, Performance, and/or Microgrid functionality tests. Tesla will confirm test results with
written reports upon request.
NOTE: Additional activities such as setup of site networking, controls features and performance
testing require site specific commissioning plans
