FeatureDescription
Bug fixes and security enhancementsFixes the issue of mismatching between the data from microinverter measurement and the meters, leading to the erroneous appearance of underproducing microinverters.

This release is being deployed via remote software upgrades for all systems.  

The following known issues have been observed in IQ Gateway software version 8.2.4264: 

Known issues:

IssueDescription
The Enphase Installer App does not support commissioning of the IQ Battery 5P to existing Solar Only sites with gateway software version 7.6.358 in Belgium, France, Luxembourg, and Netherlands 

The IQ Battery 5P is not supported with software version 7.6.358, and the Enphase Installer App cannot upgrade the system to version 8.2.86 which is needed to commission an IQ Battery 5P. Activity to upgrade all Solar Only sites to 7.6.358 to 8.2.4225 is in progress. 

If such a site is encountered, installers should inform Enphase Support to remotely upgrade the site to software version 8.2.4225 before installing and commissioning an IQ Battery 5P. 

IQ Gateway software release notes (8.2.4378)
November 1, 2024

IQ Gateway software version 8.2.4378 improves the performance of the Enphase Energy System for the countries listed below. It also supports busbar overload control and Enphase electric vehicle supply equipment (EVSE) dynamic load balancing Power Control System (PCS) features for the United States and Puerto Rico. 

  • Countries: United States, Bermuda, Brazil, Canada, Mexico, the Philippines, and Puerto Rico

  • Release notes:

    #FeatureDescription
    1Introduces the Power Control (PCS) main panel upgrade avoidance (MPUA) with busbar overload control feature for the United States and Puerto Rico

    Supports MPUA with busbar overload control for Solar Only systems with IQ8 Series Microinverters and grid-tied or grid-forming Solar Plus Batteries systems with IQ8 Series Microinverters and IQ Battery 5P.


    Power Control with busbar overload control accelerates the system payback period by enabling maximum renewable energy generation. This feature enables the safe installation of larger solar and battery systems while maximizing power through a larger backfeed—without costly upgrades to the main panel.

    2Introduces the Enphase IQ EV Charger Power Control System (PCS) feature for the United States and Puerto Rico

    The dynamic load balancing PCS feature in the Enphase IQ EV Charger is designed to monitor the total energy consumption of your home. This feature is crucial as it ensures that the charger adjusts its charging current based on the home’s overall power usage. This is supported for all models of the IQ EV Charger (IQ-EVSE-NA, 40 A, 50 A, 60 A, and 80 A) installed with an IQ Gateway or IQ Combiner.


    This enables the installation of a more powerful IQ EV Charger by avoiding main breaker trips when home loads are extremely high—saving installation costs that would otherwise be incurred by main breaker/service upgrades.

    3Supports full Off-Grid operation
    • Supports microinverter phase association during Off-Grid operation and keeps communication healthy with the gateway.
    • Provides an option to configure the system to operate Off-Grid via the Enphase Installer App or Enphase Installer Portal using a gateway REST API.
       
    4Improves IQ Battery 5P battery management unit (BMU) behavior
    • Improves State-of-Charge (SoC) calibrations under lower and higher SoC conditions.
    • Resolves an issue with battery power conversion units (PCU) pre-charge, which helps recover the battery from extreme low SoC conditions.
    • Fixes an issue with a continuous battery software reset event when a software update is tried while the battery is in a very low SoC condition.
    • Correct an issue where the BMU reads the cell voltage incorrectly and becomes non-operational when the DC Switch is turned off and on.
    • Fixes an issue seen on sites with M Series Microinverters; a rare instance of SoC drop was observed due to manual SoC calibration done by the Battery Controller as part of compensating leakage current.
    • Corrects a sudden jump in the battery SoC value due to forced calibration of the SoC.
    • Addresses incorrect State-of-Health (SoH) calibration when the battery unit charges fully and then discharges more than 50% of its capacity
       
    5Faster battery charging for Off-Grid systems with IQ7 Series Microinverters

    This software release enables faster charging and more reliable state of charge (SoC) recovery for Off-Grid batteries connected to systems with IQ7 Series Microinverters. This improvement is achieved by changing the following parameters for IQ7 Series Microinverters:

    • Reduced entry service time: The entry service time is minimized to just 1 second.
    • Increased ramp rate: The ramp rate is boosted to 100% per second.

    These enhancements are activated only when an IQ System Controller is present and functioning normally. This ensures that the controller manages grid interconnection parameters in accordance with utility requirements, rather than relying solely on the photovoltaic (PV) microinverters.

    6Improves cloud reporting behavior
    • The Enphase App sends homeowner notifications when there is a grid outage and the battery SoC is below 50%, 30%, or a very low SoC. These notifications will be sent until grid power is restored.
    • Increases the amount and frequency of data reported to the Enphase Cloud when IQ Gateway connectivity is restored after loss of internet connection.
    • Fixes an issue where IQ Battery telemetry data gets missed, leading to spikes in graphs on the Enphase Installer Portal.
    • Includes phase imbalance management (PIM) system settings in the configuration report.
    7Bug fixes and feature enhancements
    • Disables the PV breaker open detection in the IQ System Controller (version 1) since it is unnecessary for system controller versions that do not support IQ8 Microinverters.
    • Addresses meter spikes that are observed during software upgrades.
    • Resolves an issue with battery CPU memory access faults during software upgrades.
    • Corrects an issue where the IQ Batteries showed low DC voltages under fully charged conditions.
    • Fixes an issue where microinverters were down due to boot-diode failure.
    • Removes stale alarms caused by time synchronization issues between the gateway and the Enphase App.
    • Enhances security features.

Release notes:

# Feature Description
1 Improvements to system stability 1. Improves the software commissioning update sequence for IQ Batteries by verifying multimode configuration parameter update status via events, and makes sure that during commissioning grid-forming configuration is set. This also disallows the installer from proceeding to functional validation before IQ Batteries are ready, thereby preventing a microgrid collapse and delays in commissioning.

2. Fixes an issue with automatic circuit phase detection for 208 V line-to-line split-phase 120-degree phase shift systems with IQ7 Microinverters.

3. Fixes an issue where grid transition failures happened during the following scenarios:
 
  1. Low Frequency Ride Through (LFRT) events
  2. High Voltage Ride Through (HVRT) events

4. Fixes an issue of microgrid regulatory shutdown after islanding detected due to grid outage, by changing the IQ System Controller off-grid under voltage trip time from 100 ms to 300 ms.

5. Fixes an issue where High-Frequency Ride Through conditions cause microgrid collapse.
2 Enhancements to interface with the Enphase Cloud 1. Supports faster retrieval of Wi-Fi SSIDs from the IQ Gateway to Enphase App using Message Queuing Telemetry Transport (MQTT) protocol over any active internet connection. This lets the homeowner connect to a Wi-Fi network faster and without connecting to the gateway’s local Access Point (AP) mode.

2. Supports automatic AP mode activation whenever an IQ Gateway loses its internet connection. This allows the homeowner to configure the alternate Wi-Fi network via AP mode in the absence of an internet connection, and without pressing the physical AP mode button on the IQ Gateway.

3. Supports setting up the polling and reporting intervals for a system with cell modem connectivity, and prevents reset of interval values due to a change in IQ Gateway diagnostic mode.

4. Improves handling of sending performance reports at regular intervals without any loss of any performance report.

5. Supports REST APIs for enabling and disabling the MID open detection and PV Breaker open detection logics using micro-DMIR change.
3 Improvements to IQ Battery behavior 1. Improves system Sunlight Jump Start response time.

2. Prevents grid transition failure due to IQ Battery microinverters slow ramp, triggered by momentary cessation, kicked in just before anti-islanding detection.

3. Supports enabling and disabling Permission To Operate (PTO) for IQ Batteries on site from the Enphase Installer Portal. The feature prevents IQ Batteries from discharging to load or grid until the permission is enabled, and ensures IQ Batteries are able to maintain a healthy State of Charge (SoC). The status of the IQ Battery function is indicated in Enphase Installer Portal as a stateful event whenever the IQ Battery function is disabled.

4. Fixes an issue where an IQ Battery stops discharging to load when the peak hours overlap with must charge duration.

5. Improves the battery controller detection of microinverters in an IQ Battery by checking the operational state of microinverters.

6. Fixes an issue where the power from IQ Batteries was not being used to support the load when aggregate SoC is greater than reserved SoC.

7. Fixes an issue where the aggregate SoC drops in M Series Microinverter systems when Full Backup mode is selected.

8.Prevents the periodic forced SoC calibration in the Battery Management Unit and maintains battery SoC at approximately 97% by sending a manual SoC calibration message to the BMU after checking cell voltages.
4 Improvements to the commissioning and software upgrading process 1. Improves the software upgrade process by checking versions of all the microinverters in IQ Batteries and triggering automatic upgrade if any microinverter’s firmware version is different from other microinverters.

2. Fixes an issue where the Enphase Installer App was blocked and showing an error while an IQ Gateway software upgrade was in progress.

3. Fixes an issue where multiple firmware upgrade retries happen when the IQ Battery firmware is not updated.

4. Improves the commissioning experience via the Enphase Installer App by logging the upgrade flow in IQ Gateway, including status messages and error messages.

5. Fixes an issue where a software upgrade using the Enphase Installer App fails due to communication loss between the IQ Gateway and the Enphase Installer App.

6. Enhances inventory report with inclusion of the phase association information of each inverter.
5 Improvements to Zigbee and Wi-Fi communication 1. Improves handling of unknown grid mode conditions by increasing the unknown grid mode expiry timer to 12 hours to ensure the IQ System Controller connects back to the grid.

2. Enhances the Zigbee communication loss recovery mechanism during failures.

3. Enhances MQTT client connection loss with MQTT broker recovery mechanism by refreshing the Domain Name System (DNS) cache.

4. Fixes an issue where Zigbee communication between the IQ System Controller and the IQ Battery becomes stuck after an IQ Gateway powers down.

5. Fixes an issue where the Zigbee dongle was undetected after a software upgrade.
6 Bug fixes and feature enhancements 1. Fixes an issue where multiple retries were required to upgrade the software on IQ Batteries.

2. Fixes an issue where repeated battery BMU reset events were reported.

3. Fixes an issue where a generator relay toggles until off-grid to on-grid transition sequence is completed.

4. Fixes an issue where the update manager did not detect the existence of an update image after the software upgrade was interrupted.

5. Removes the repeated “Systems Ghz Comms Signal Low” events which occur after a software upgrade.

 

This release is being deployed via remote software upgrades for existing systems.
