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:
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.
