GM Energy V2H Bundle Installation Manual 12
Before You Begin
Upon arrival, evaluate the site:
1. Review the design and verify the actual physical details at the site:
a. Adequate mounting surfaces and O.C. (on center) stud distance when applicable.
b. Existing electrical system and points of interconnection.
c. Ensure site is powered by 120/240 VAC service – never with 208 VAC service.
d. Feeder/long conduit runs and backup circuits.
2. Verify equipment layout:
a. Verify adequate space for equipment.
b. Verify that wireway and conduit Balance of System (BOS) plan makes sense and is viable.
c. Verify that Charger location will enable charge cable to reach vehicle charge port without creating tension at the
charge cord connection to the vehicle.
3. Confirm adequate Wi-Fi signal strength at the determined mounting location of both the GM Energy PowerShift
Charger and Home Hub.
a. Signal strength of –75dB or greater at both locations is required in order to commission this system. A stronger
Wi-Fi signal will be less negative, or closer to zero.
i. Various free mobile and web apps will allow you to measure this value prior to installing the equipment. Once
the system is wired up, signal strength can be measured through the PowerShift Install App for
commissioning.
b. If you measure insufficient Wi-Fi signal at either location, a range extender or booster may be required to ensure
consistent cloud connectivity.
i. If Wi-Fi signal is insufficient, a mobile hotspot may be used during commissioning. The system may then be
connected to the home Wi-Fi network through the vehicle’s mobile app after commissioning, if required.
4. Prepare equipment:
a. Remove equipment from packaging, keeping track of all fasteners and screws!
b. Remove covers and place in non-work area to avoid damage.
c. Prepare knockouts and conduit fittings; and install any Hub accessories as necessary
As the installation progresses, be prepared to capture necessary job closeout photos, keeping in mind that some
photos can only be taken during the installation process. GM Energy provides recommendations of job closeout photos
to take in the Job Closeout section, as these may be beneficial for both the installer and GM Energy to best support the
customer if they require service in the future. However, these photos are not required by GM Energy; please refer to your
installation company if they require any specific closeout photos or information.
