What's New in Generac Industrial Connectivity

Generac Link Manager Update - 2025.04.08

Release Date: Thursday, April 10, 2025

We plan to release the latest version to Production on Thursday, April 10, starting at 8:00 AM Eastern. This release includes several new features and key fixes.

Features

Foreign Language Translation Support
Translations have been added in preparation for future international deployments. Please note that this feature is currently disabled for all customers.

TREND Tab
The TREND tab within the Equipment pages has been converted to React for improved performance and usability. While users may notice minor visual changes, functionality remains consistent.

Notable improvements include:

• A more user-friendly CUSTOM date/time picker.

  

• Enhanced visualization of data gaps, as trending graphs now display all data points evenly across the X-axis.

  

Reminder: Users will continue to see an error if they attempt to trend data over a window greater than 31 days. This is consistent with previous behavior.

Fixes

• Subscription Status: Resolved an issue where the Subscription Status column on the Subscription Administration page was misaligned.

• Restart Live Data Streaming: Fixed a bug where the RESTART STREAM link on the LIVE tab of the Equipment pages was not functioning properly.

• Browser Cache: Addressed an issue where Equipment data across tabs (LIVE, TREND, JOURNAL, REPORT, ALARM, SCHEDULE) would not load correctly unless the browser cache was cleared.

Deployment Impact

While customer impact should be minimal, users may experience brief periods of application non-responsiveness during the tenant installation process.

Generac Link Manager Update - 2025.03.26

Release Date: Thursday, March 27, 2025

We are excited to announce the latest Generac Link Manager version release. This release includes new features, updates, and bug fixes to enhance performance and user experience.

Features

Embedded Generac Link User Survey for Select Tenants

We want to hear from Generac Link End Users about their overall experience with the product and their level of satisfaction. Our goal is to gather valuable feedback to inform and improve future design updates.

Site Name Changes Enhancement

Site Name updates in the 'Site and Equipment Configuration' wizard now take effect immediately, without requiring a cache clear.

Time Zone Definition Adjustments

Improved logic to account for time zone definition differences based on the operating system. This will prevent loss of time zone selection when saving on a Mac machine and then reopening in Windows.

Updates

Subscription Administration Enhancements

The 'end date' was updated to reflect 365 days, aligning with Zoho. In addition, we improved the clarity of the 'Subscription' and 'Status' descriptions.

Enhanced Data Streaming Configuration

Site Summary and Equipment data streaming settings are now configurable per tenant instead of globally.

Fixes

API Token Expiration Handling: Fixed an issue where expired M2M (API) tokens led to excessive error logs (tokens expire after 24 hours). Users are now redirected to the Main Map after their API session token expires.

Generator Run Reports Accuracy: Resolved an issue where reports were incorrectly created for Transfer Switches.

User Email Domain Length Fix: Generac Link Users with email domains longer than three characters can now be added successfully.

User Permissions Compliance with Feature Flags: Resolved inconsistencies where some User Permissions did not adhere to Feature Flag states.

Gateway Data Payload Processing: Fixed an issue preventing proper processing of Gateway discrete data payloads exceeding 50 tags.

Deployment Impact

While customer impact should be minimal, users may experience brief periods of application non-responsiveness during the tenant installation process.

If you have any questions or concerns, please reach out.

Generac Link Manager Update - 2025.03.12

Release Date: Friday, March 14, 2025

We are excited to announce the upcoming release of Generac Link Manager version 2025.03.12. This release introduces new features, performance enhancements, and critical fixes to improve the user experience.

New Features & Updates

Site & Equipment Configuration Enhancements:

• Updated Site Details with latitude/longitude validation checks and improved time zone selection filtering.

• Fixed a timeout issue affecting the Subscriptions Administration page.

• Corrected a bug where subscription start and end dates were displaying incorrectly (off by one day).

Deployment Impact

While customer impact should be minimal, users may experience brief periods of application non-responsiveness during the tenant installation process.

If you have any questions or concerns, please reach out.

Firmware Update Required for Powerzone ProSync Controller

What’s Changing

To ensure optimal performance and prevent potential issues, we recommend updating the firmware on your Powerzone ProSync (PZPS) controller to version 1.23.2 or later.

Why Is This Important?

Firmware versions below 1.23.2 may lead to:

• Loss of communication with the Generac Link gateway

• Random Low Coolant Level alarms

Updating to the latest firmware helps maintain system stability and performance.

How to Update

Follow the firmware update procedure outlined by Generac Power Systems.

Generac Link Manager Update - 2025.2.27

Release Date: Thursday, February 28, 2025

We will deploy the latest version of Generac Link (2025.2.27) to Production clients on Thursday, February 28, 2025, starting at 8:00 AM Eastern. This update includes performance enhancements, UI updates, and bug fixes to improve the overall experience.

Release Features

• Cache Performance Improvements – Users will experience significantly faster performance when retrieving single-equipment Sites.

• Site and Equipment Configuration Admin: The Site and Equipment Configuration has been fully converted to React, a JavaScript library for creating website screens. Users may notice a slight difference in appearance, but the performance of these pages remains unchanged.

Release Fixes

• Alarm History Timezone Correction – Alarm history entries will now correctly display in site time rather than browser time.

• Map Pin Display Fix – Resolved an issue where clustered pins on the main map appeared elongated.

• Site Permission Handling – We fixed an issue where a User’s Site Permissions could be reset if the record was saved before Sites were retrieved from the cache.

Customer Impact

• Minimal downtime – The Generac Link UI may be non-responsive for approximately 15 minutes during deployment.

• Full regression testing will be conducted across all Production client environments to ensure system stability.

Upcoming IoT Suite Release

We are also planning a separate release for the Generac Engineering IoT Suite apps on Thursday, March 6, 2025. This release will introduce support for CANbus deployments. Since these are internal applications, this update will not impact customers.

If you have any questions, please reach out.

Attention Generac Industrial Dealers: Subscription Management

2024 was an exciting year for the Generac Energy Services team with the introduction of the after-market and factory-attached advanced gateway.  We appreciate your support and feedback, which has brought us to the next stage of introducing subscription management.  Last year, we moved the subscription purchasing out of GenService and into the Generac Link Manager platform under the Subscription Administration page. Your site administrator can provide your user login access if needed. 

Starting on March 1st, 2025, new invoices will be sent out to sites with active subscriptions. Sites that were deployed with a pre-purchased subscription from GenService will be reflected in the system and will be invoiced when the pre-purchased subscription expires.  If the pre-purchased subscription has already expired, an invoice will be generated on March 1st. 

In preparation for the invoice, we ask for your help confirming that subscription plans and statuses in your portal are accurate and that we have the proper billing contact on file.  For more information on subscription management, refer to the Subscription Management help article in the support knowledge base accessible via the Generac Link Manager application menu. 

 For subscription accuracy, please do the following: 

1. Log in to your Generac Link Manager portal and review your subscriptions. Subscriptions with a March 1st end date will be billed on March 1st. 

2. Confirm if any subscriptions set to bill on March 1st need to be canceled. 

3. Ensure that subscriptions are assigned to the correct plan (IDC or Customer). If the customer add-on is not selected before the expiration date, customers may lose access to the site

We are emailing each IDC to confirm that we have the correct billing contact on file. If you need assistance, contact Kristine Schindler in Customer Success at kristine.schindler@generac.com. 

Generac Link Manager Update

Release Date: Thursday, February 13, 2025

On Thursday, February 13, we plan to release the latest version of Generac Link Manager to Production. This release aims to enhance user experience and application performance through key updates and improvements.

New Features

• Subscription Management: Subscriptions marked for cancellation at the end of a free trial period will now be updated to ‘non-renewing’. This option is available only to users with permission from 'Subscription Administration' on the main menu.

• Alarms: The Alarm Tab has been fully converted to React, a JavaScript library for creating screens for websites. Users may notice a slight difference in appearance. However, the performance of these pages remains unchanged.

• Add User: Only Users with 'User Administration' permissions will see this option on the main menu.

• User Permissions: Only Users with 'User Administration' permissions will see this option on the main menu. In addition, search by entering part of a name was added to the User Field and the site access fields, Available Sites and Sites Selected.

Users may experience a few minutes of inactivity on the Generac Link app during the install window, which is scheduled from 8 am to 11 am Eastern time. To minimize disruption, the update will be delayed for any customer who has a dispatch scheduled to run during the install window.

Generac Link Manager Banner Goes Live Thurs., Dec. 19, 2024

When logging into the platform after Thursday at 0700 EST, when system maintenance is scheduled, customers will be welcomed with a fresh Generac Link Manager banner. The new logo for Generac Link Manager will appear in the upper left of the browser window, adjacent to your company branding (not shown).

If utilizing the platform around this time, you might experience inactivity or reduced responsiveness lasting approximately five minutes while the installation is deployed to your organization’s dedicated instance. We expect performance to quickly return to normal once system maintenance and installation are complete.

We’ve resolved an issue with the Journal history timestamp. The minor correction has been rolled into this version.

Be sure to check the knowledge base and this page for the latest information to help you in your connectivity journey. Lots of new features and optimizations are in the works for 2025.

Generac Link Retrofit Gateway and Harness Kit: Coming Soon!

We are rolling out upgraded hardware—a new advanced gateway for after-market customers as well as a new harness kit. These components seamlessly enable the customer’s connected energy journey in Generac Link Manager. Support continues for our growing number of installations leveraging the legacy hardware.

Be sure to refer to the FAQs page for additional details on parts for existing hardware.

Power Zone^® Pro Sync 485 Firmware: Upgrade Needed

For Modbus RS485 to work correctly between Power Zone Pro Sync and the Generac Link gateway, firmware on Power Zone Pro Sync must be updated to 1.23.2. Otherwise –99 values may appear in place of valid telemetry in the Generac Link Manager interface.

Release Information for Dec. 5th, 2024

We rolled out a patch to a minor issue so that Group Schedules now properly populate the schedule history. We did have a report that some of those records were not rendering on the page.

Sept. 27, 2024: Subscription Management Just Released

The subscription management feature is now live for IDCs. Be sure to jump to the Subscription Management topic for details. The new features streamline the easy steps in the monitoring application and enable you to stay on top of upcoming expirations of trial licenses.

The landing page now features quick access to the fresh-looking List View for sites, utilizing an easy-to-find modal on the Map View or landing page, with filters by name, gateway serial number, or active alarm status. This replaces the Site List menu formerly in the banner. Be sure to see the full details in the Fleet Management topic.

The user can easily filter the list view by entering the name or gateway ID. Partial entries are accepted.

Stay in touch by checking this page for future enhancements in the coming weeks.

Sept. 10, 2024: Shipment Information

We have learned that some factory-attached connectivity gateways shipped with the cellular antenna disconnected from the gateway. These cables are normally pre-connected from the factory. The issue has been corrected for new shipments.

For existing inventory, please confirm that the pigtails from the gateway enclosure are connected to the antenna cables as illustrated in the following diagram (Red > Red/Black and Blue > Blue) prior to deployment. This will ensure the gateway has adequate cellular signal strength to communicate with the connectivity platform.

Please refer to our knowledge base for further information on wiring and connections.

Factory-Attached Connectivity Gateway Live this June!

The Advanced Gateway, designed to streamline asset connectivity in enterprise power applications, is installed at the factory by default for large industrial generators. Please refer to this page for the models affected. The Advanced Gateway uses Modbus to connect to most generator controllers. Schematics and other detail are provided in our Advanced Topics section.
