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.

Note: Enphase only deploys this software release to system configurations 1 to 7, as described above in the “Supported system configurations” section. Other configurations will be upgraded in a future software release.

# Feature Description

1

Improvements to system stability

  1. Fixes issues wherein Sunlight Jump Start does not happen. These are for rare scenarios, like when the System Shutdown Switch is turned back on after it was turned off, or when a generator has failed to start the system.

  2. Fixes a rare issue wherein a system restart does not happen if a generator failure happens while the system is in off-grid mode with the generator connected.

  3. Increases the reliability of on-grid to off-grid system transitions by improving handling of high-frequency ride-through conditions.

  4. Increases the reliability of off-grid to on-grid transitions by improving handling of conditions wherein the grid comes back to normal operation with a low frequency.

  5. Fixes an issue where the IQ System Controller keeps trying to connect DERs and form a microgrid even when the utility grid is available. This is only seen in the rare case when the utility grid voltage/frequency is outside the enter service limits for DERs per the standard followed by the region/utility. This has been fixed by ensuring the IQ System Controller can power the home via grid if the voltages are safe to connect to and keep the DERs disconnected—hence not violating entry service conditions.

2

Improvements to the commissioning and software upgrading processes

  1. IQ Gateway software now reports the status of battery inverter mode (grid-tied, multi-mode on-grid, multi-mode, off-grid, etc.) to the Enphase Installer App. This is displayed in the Enphase Installer App during functional validation.

  2. Reduces commissioning time for IQ8 Microinverters by optimizing the communication between the IQ Gateway and IQ8 Microinverters during provisioning. Provisioning steps repeated due to IQ8 Microinverters rebooting post-propagation of system configuration are reduced, leading to a reduction in overall provisioning time.

  3. Enhances logging for IQ Battery 3/3T/10/10T and IQ System Controller 1/2 upgrades by reporting the names of the files, along with download start and download end events, to the Enphase Cloud.

  4. Improves the reliability of software updates when the internet connection is via a cellular modem. This is achieved by increasing the timeout limit for specific files that are large in size, which in turn enables more retries during the download of these files over cellular data.

  5. Reduces the time taken to update the IQ System Controller 1/2 firmware from the IQ Gateway by providing flow control during transfer of packets via Zigbee.

  6. Improves the software upgrade process to automatically handle conditions like low state of charge and the system going off-grid and back on-grid, as well as devices losing Zigbee connection and then reconnecting.

  7. Fixes an issue wherein IQ8 Microinverters fail provisioning. This is a very rare scenario wherein an IQ8 Microinverter fails to receive system configuration during provisioning.

  8. Fixes an issue wherein the IQ Gateway reboots upon completion of device commissioning using the Enphase Installer App.

  9. Fixes an issue where the IQ System Controller 1/2 firmware is not updated immediately after commissioning and functional validation.

  10. Fixes an issue where system configuration files are propagated to the IQ Battery 3/3T/10/10T and IQ System Controller 1/2 multiple times.

  11. Fixes an issue where specific IQ Battery models (SKU: B03-A01-US00-1-3) were not upgrading to the new Battery Management Unit (BMU) firmware and causing reset events.

  12. Fixes an issue where circuit phase auto-detection feature was not supported for IQ7 Series Microinverter systems.

Improvements to system behavior

  1. IQ System Controller 2 includes a hardware protection feature wherein it detects AC voltage on either side of the PV breaker and goes to a safe state if there is a significant difference in the magnitude of the AC voltage readings from either side of the breaker while the internal PV relay is closed. The PV relay is the built-in protection for grid-forming IQ8 Series Microinverters on the PV or solar port (DER1) of the IQ System Controller 2. This rule has been modified to be active only when:

    • The IQ System Controller 2 is commissioned.

    • IQ8 Series Microinverters are connected to the PV port.

    • There is a 20 V delta in AC voltage readings from either side of the PV breaker after 30 ms of the PV relay closing (this was 20 ms earlier).
     

    Once triggered, the rule raises the PV breaker open error and only opens the PV relay to keep the system safe, instead of all relays as on previous software releases. In addition, the PV breaker open error automatically clears after 30 seconds for the first three occurrences. If any more occurrences are detected, then the error persists and requires Enphase Support intervention to clear.

    These changes improve the hardware protection feature while avoiding false detection and any homeowner or installer inconvenience due to false detection.

  2. Retrieves more debugging data from the Battery Management Unit (BMU) for IQ Batteries, and sends the same to the Enphase cloud to enable better system monitoring and debugging.

  3. Improves the handling of Grid Services commands by ensuring the commands persist across IQ Gateway reboots.

4

Improvements to IQ Battery behavior

  1. Supports battery-only backup systems (configuration 9 as described in “Supported system configurations” above) by resolving issues like the IQ Gateway rebooting and the IQ Battery 3/3T/10/10T getting disconnected due to false triggers of the PV breaker open rule. Improvements to the PV breaker open rule are described in the “Improvements to system behavior” section.

  2. Fixes an issue wherein the status of the DC ON/OFF switch was not accurately communicated by the IQ Battery 3/3T/10/10T and IQ Gateway to the Enphase Cloud.

  3. Fixes an issue wherein the IQ Battery 3/3T/10/10T would not maintain the reserve state of charge (SoC) by charging from the grid.

  4. Validates if the Current Transformers (CTs) used for monitoring consumption are missing or have failed. The IQ Battery 3/3T/10/10T are set to an idle mode if Consumption CTs are missing or have failed to ensure the Import-Only mode per IQ Battery 3/3T/10/10T UL Power Control System (PCS) Certification Requirements Decision (CRD) is not violated in case of CT failures.

  5. Fixes an issue wherein the IQ Battery 3/3T/10/10T does not charge with maximum power when the system is off-grid with a generator connected.

5

Improvements to Zigbee and Wi-Fi communication

  1. Reduces profile propagation time from the IQ Gateway to the IQ System Controller 1/2.

  2. Supports remote restarts of the Zigbee communication processes inside the IQ Gateway software through the Enphase Installer Portal. This is to aid in remote debugging and improve customer support capabilities.

  3. Improves the connectivity to Wi-Fi networks by ensuring the parameters used to tune the Wi-Fi module’s front-end are appropriate.

  4. Fixes the display of an incorrect battery state in Live Vitals in the Enphase App and Enphase Installer App when batteries have lost Zigbee communication.

6

Bug fixes and feature enhancements

  1. Reports load name and battery profile via local API to the Enphase App to enable the app to display these details when the system has lost cloud connectivity and is reporting to the app via local connectivity (i.e., via the local area network, assuming the phone running the app and the IQ Gateway are on the same local area network).

  2. Enhances IQ Gateway security by integrating the Cloud Certification Authority (CCA) into software signing.

  3. Fixes an issue wherein the IQ Battery 3/3T/10/10T was not charging when the Power Export Limit (PEL) is enabled in the grid profile and the battery is in savings mode.

  4. Fixes an issue wherein many “Systems GHz Comms Signal Low” events are sent to the Enphase Cloud. Note that the excessive number of events are not visible to the homeowner or installer. The number of events is reduced in this software release to enable the Enphase Support team to use internal tools to better support homeowners and installers.

  5. Fixes an issue where the Consumption CT measures a very high value at the time of an IQ Gateway software upgrade.

  6. Fixes an issue wherein, post-upgrade to 4.40.04 firmware, IQ7+ Microinverters lose communication and do not produce power.

 

This release is being deployed via the Enphase Installer App for new systems as well as via remote software upgrades for existing systems. Remote software upgrades for this release will exclude systems that have only cellular connectivity.
