Bug fixes |
|
This release is being deployed via an Enphase Installer App upgrade for new systems and remote software upgrades for existing systems.
The following known issues have been observed in IQ Gateway software version 7.6.172.
Known issues:
| # | Issue | Description |
|---|---|---|
|
1 |
Negative power consumption reported in Enphase App graphs |
Negative power consumption graphs in the Enphase App can occur when there is a significant delay in data reporting from an IQ Battery to an IQ Gateway. This delay could be due to a software update, network glitch, or some other reason. When data reporting from the IQ Battery resumes, all the accumulated energy data is reported to the IQ Gateway at once, leading to an incorrect power estimation for that period of time. This event has no impact on system operation and will be fixed in upcoming software releases. |
|
2 |
Zigbee communication dongle stuck in unknown state |
For a small set of sites, the Zigbee dongle gets stuck in an unknown state by the IQ Gateway at the start of provisioning. An IQ Gateway restart using a breaker, or a remote reboot instruction issued to the IQ Gateway via Enphase Support, can be used to ensure the Zigbee dongle is successfully detected. This issue will be fixed in upcoming software releases. |

The following known issues have been observed in the IQ Gateway software version 7.6.168 release:
Known issues:

# |
Issue |
Description |
|
1 |
A large spike in consumption is reported in the Enphase App when the IQ Gateway software is upgraded to v7.6.168 from a version earlier than the v7.6.x releases |
The Enphase App reports a huge spike in consumption whenever the IQ Gateway software is upgraded to v7.6.168 from a version earlier than the v7.6.x releases. Enphase mitigates this by deleting the records of that day for the system owner, thereby ensuring owner-facing energy consumption figures are not affected by this issue. |
|
2 |
Non-detection of Zigbee communication dongle |
For a small set of sites, the Zigbee dongle is not detected by the IQ Gateway at the start of provisioning. An IQ Gateway restart using a breaker, or a remote reboot instruction issued to the IQ Gateway via Enphase Support, can be used to ensure the Zigbee dongle is successfully detected. This issue will be fixed in upcoming software releases. |
|
3 |
AC disconnect failure event reported in the Enphase Installer Platform for sites with third-party inverters |
When the power exported or imported at the point of common coupling (PCC) exceeds allowed imbalance thresholds due to large, single-phase loads at a site, the IQ Gateway tries to balance the phases by limiting PV power production across phases. This is followed to reduce the home’s imbalance at the PCC. If the imbalance continues, the IQ Gateway issues an AC Disconnect command which can disconnect the PV from the grid via an external contactor. The external contactor’s coil is connected to the IQ Gateway relay terminals (refer to the IQ Gateway wiring label for relay terminals “NO” and “C”). Third-party string inverters are not controllable by the IQ Gateway. In such systems, power production from PV continues after the IQ Gateway issues an AC Disconnect command, leading to AC Disconnect failure events being reported by the IQ Gateway to the Enphase Installer Platform. These events have no impact on system operation and will be fixed in upcoming software releases for systems with third-party string inverters. |
|
4 |
Unnecessary curtailment of solar power generation for sites with M Series and IQ7 Series Microinverters |
When a system has mix of IQ7 Series and M Series Microinverters, the IQ Gateway is unable to complete phase aggregation. That means the IQ Gateway is unable to identify the phases to which various IQ7 Series Microinverters are connected. Due to this phase aggregation failure, these microinverters do not follow the instructions from the IQ Gateway to change power output. Such changes are required to comply with power export limits or thresholds for imbalance allowed across phases. This can lead to excess curtailment of solar power generation in certain cases. The probability of this occurrence is low and will be fixed in upcoming software releases. |
|
5 |
Negative power consumption reported in Enphase App graphs |
Negative power consumption graphs in the Enphase App can occur when there is a significant delay in data reporting from an IQ Battery to an IQ Gateway. This delay could be due to a software update, network glitch, or some other reason. When data reporting from the IQ Battery resumes, all the accumulated energy data is reported to the IQ Gateway at once, leading to an incorrect power estimation for that period of time. This event has no impact on system operation and will be fixed in upcoming software releases. |

Release Notes:
| # | Feature | Description |
|---|---|---|
| 1 | Enhancements for system stability | a. Improves microgrid stability in rare scenarios which in the past resulted in functional validation failures or voltage and frequency oscillations when OFF Grid. b. Removes incorrect battery power display as 0 for line 2 by sending the right phase configuration to cloud. c. Improves grid transitions by increasing ride through time for OFF Grid frequency limits. d. Fixes an issue for systems with generators where microinverter power production and IQ Battery discharge levels appear to be fluctuating when the system is OFF Grid and generator is operating at less than a minimum recommended load. e. Fixes an issue where IQ Battery oscillates between charging and discharging when at the reserve State of Charge (SoC) limit. The error was due to battery SoC maintenance logic using a marginally higher reference SoC to trigger SoC maintenance. SoC maintenance is triggered at the reserve SoC limit now and avoids errors. f. Ensures microgrid is formed and is retained for up to 12 hours even if a communication loss has happened prior to a grid outage. g. Enables IQ8 + IQ Battery systems to Sunlight Jump Start and power on by toggling the DC switches on the IQ Batteries when there is a Rapid Shutdown exit at night. Prior to the release in the rare scenario when the Enphase System Shutdown Switch (the Rapid Shutdown Initiator for IQ8) was used to turn the system off, while OFF Grid, the system could only be turned back on when there was PV power, i.e., during the daytime or when the utility grid power returned. h. Fixes an issue where PV exports to grid momentarily even when the system is configured with a zero PV export limit. In prior releases, when the Power Control Systems (PCS) implementation that ensures no export to grid from battery is triggered, due to a step change in load, a momentary export to grid from PV is seen. |
| 2 | Improvements to commissioning | a. Improves software upgrade architecture. Upgrades pause when MID is open i.e., the system is OFF Grid and resume when MID is closed i.e., the system is ON Grid. b. Provides MQTT (MQ Telemetry Transport) based streaming of Power Line Communications (PLC) frequency and signal strength to cloud. This is exercised during periods when the IQ Gateway is not transmitting or receiving PLC communication. The MQTT enables the Enphase cloud to show a frequency domain view of the data post a Fast Fourier Transform (FFT). This view can be used to determine if the PLC communication in a system can be degraded or disrupted by noise in the frequency band that the IQ Gateway and microinverters use for communication. c. Improves the reliability of firmware upgrades by retrying certain missed messages. d. Improves reliability of firmware upgrades during commissioning by adding more retries to cover multiple failed attempts. e. Provides “Total bytes remaining to transfer” and “Total bytes to transfer” information via REST API to Installer app during the commissioning process, enabling installers to get a better idea of total firmware upgrade time as well as time remaining for firmware upgrade to complete. f. Avoids opening of PV and battery relays by preventing IQ System Controller update/reset during the configuration of Current Transformers (CTs). This avoids installers having to wait for relays to close to continue CT configuration and consequently reduces commissioning time. g. Reports a “DC is turned on before AC” event to cloud when the DC switch on an IQ Battery is turned on before the IQ Battery is connected to AC power. This event indicates an incorrect power on sequence was followed for the IQ Battery. IQ Batteries must be connected to AC power before their DC switches are turned on. The event is used by Enphase cloud and Enphase customer support to educate installers and help installers avoid potential IQ Battery field failures due to use of the incorrect power sequence. h. Avoids unnecessary firmware updates for configuration files by exposing the version of the configuration files and checking the same in IQ Gateway software before upgrading. i. Speeds up the inventory retrieval processes which determines the devices (IQ Batteries, IQ System Controller and components within) are actively connected to the IQ Gateway to reduce overall commissioning time. |
| 3 | Enhancements to Zigbee communication | a. Avoids IQ Gateway reboot by fixing a crash of the process handling Zigbee communication. b. Reduces homeowner facing errors for lack of communication between IQ Gateway and IQ Batteries or IQ System Controller by raising the errors only if automatic recovery of Zigbee dongle is tried and has failed. c. Adds heartbeat messaging between IQ Gateway and IQ Batteries or IQ System Controller to detect scenarios where the Zigbee radio is nonresponsive so that automatic recovery is initiated. Note that every recovery attempt shows a Zigbee communication failure event for the homeowner. This event is automatically cleared post successful recovery. d. Fixes an issue wherein multiple events of IQ Batteries or IQ System Controller losing Zigbee communication are shown to the homeowner in Enphase App. This is done by avoiding a situation wherein the IQ Gateway repeatedly floods the Zigbee network with broadcast messages which prevent communication and then lead to communication failure events. e. Adds retries to IQ Gateway software communication via USB to Zigbee dongle to avoid IQ Gateway manual reboot when a Zigbee dongle communication error occurs. f. Supports firmware updates for old and new Zigbee dongles at the same time. g. Enhances Zigbee connection recovery by incorporating an automatic Zigbee module reset on IQ Batteries and IQ System Controller. This reset triggers when the Zigbee module in these devices is stuck in an erroneous state for a long period of time after having exhausted the allowed timeout for lack of communication with Zigbee dongle connected to the IQ Gateway. h. Improves Zigbee communication recovery by avoiding an immediate network change when the Zigbee USB dongle is disconnected and reconnected on the IQ Gateway. IQ Batteries and IQ System Controller can join the same network they were on and avoid a long-term lack of communication with IQ Gateway. i. Reduces Zigbee communication losses due to potential non-volatile memory corruption issues. j. Improves microgrid resiliency to Zigbee communication loss between IQ System Controller and IQ Gateway by improving communication between IQ System Controller and IQ Batteries which enables the batteries to stay operational and keep forming a microgrid. |
| 4 | Reintroduces grid services support | a. Restores Grid Services programs that had been inadvertently disabled by an earlier software release. b. Supports new modes for battery charging and discharging which can be used via Grid Services API offered by Enphase: • Charge from grid • Charge from solar with load priority - Excess power will be used to charge battery after serving loads • Charge from solar with battery priority - Excess power after charging the battery will be used to serve the loads • Discharge to load - Battery discharges to a level which is the minimum of the setpoint received from the Grid Services API and the load seen on the site • Discharge to net load - Battery discharges to support load that exceeds the PV production amount. c. Adds the ability to set Idle mode for IQ Batteries via Grid Services API. d. Adds capability for • Back-to-Back, overlapping and nested Grid Services events • Multiple commands can be sent to IQ Gateway/Envoy S by Grid Services API and each command has a delay and a duration timer. Delay specifies the time from command receipt till the point in time when the command should be active. Duration specifies the duration of time for which the command should be active. • Discharging or charging batteries at a specific set point rather than just at rated power • Automatic move to idle state (prevent charge or discharge) once utility-set target State of Charge is reached e. Enhances system behavior to honor discharge commitments in case of partial failure of IQ Batteries in a system. For example, if one IQ Battery fails the other IQ Batteries will increase their output power as much as possible to compensate for the battery which is not functional. f. Ensures the Grid Services data persists across IQ Gateway/Envoy S reboots and system resets. |
| 5 | Enhanced interface with Enphase Cloud | a. Fixes an issue wherein any local issue in IQ Gateway software while creating a performance report (microinverter, battery and meter data along with events) resulted in the abandoning the process of sending the entire performance report to Enphase cloud. Now the performance report creation continues with readings and events that do not show issues and the resultant report is sent to Enphase cloud. b. Enables real-time alerts about grid outages for homeowners via Enphase App. IQ Gateway software sends a real time notification report to Enphase cloud containing date and time information regarding when the outage began to support this feature. c. Allows quick debugging of IQ Gateways by Enphase customer support and engineering teams. IQ Gateway software opens a tunnel in response to a MQTT (MQ Telemetry Transport) command received from Enphase cloud. Earlier, a tunnel required manual intervention at the IQ Gateway or waiting for the ping interval set on IQ Gateway so that it communicates with Enphase cloud and receives the command to open a tunnel. d. Fixes an issue wherein a system would reject an Enphase app-based command to go On Grid, incorrectly citing a lack of grid i.e., power outage. This issue was seen in a prior software release, when the Enphase App was used to command the system to go ON Grid, after having previously commanded the system to go OFF Grid. e. IQ Gateway software reports a special event for IQ Batteries which do not sense AC voltage. This event is exposed to installers and is also used by Enphase customer support to educate installers on the risk of a potential RMA due to IQ Batteries discharging down to irrecoverable State of Charge (SoC) levels while turned on and not connected to AC power. f. Provides a new REST API to update IQ Battery serial numbers into non-volatile memory as a safeguard against memory corruption causing batteries to lose their serial number. g. IQ Gateway software immediately sets reserve the State of Charge (SoC) level received from Enphase cloud on to the IQ Battery instead of waiting for the next planned write cycle. This enables all batteries to charge/discharge as required by the new reserve SoC limit, immediately eliminating delays in the system’s reaction to reserve SoC changes. |
| 6 | Improvements to system restart while in a microgrid | a. Post a microgrid collapse due to overload, the IQ Battery firmware now does at least 40 system restart retries to increase the likelihood of a successful restart. The restarts are spaced out in exponentially increasing time intervals. b. Fixes an issue wherein a false detection of a PV breaker being opened by IQ System Controller during a Sunlight Jump Start leads to repeated failures of the system restart. |
| 7 | Bug fixes and feature enhancements | a. Fixes an issue wherein IQ Battery is charging from grid to maintain the State of Charge (SoC) even when SoC is higher than reserve SoC for backup-capable sites and when above Very Low SoC (VLS) threshold for Grid Tied non-backup battery sites. As of this IQ Gateway software release IQ Battery only charges from grid when SoC is below reserve SoC for backup-capable sites and when SoC is below VLS for Grid Tied sites. b. Improves Rapid Shutdown exit behavior i.e., behavior when the Enphase Energy system is turned on using the Enphase Energy Shutdown Switch (Rapid Shutdown initiator for grid forming IQ8 microinverters). If Rapid Shutdown exit happens when grid is available, the home is immediately connected to the grid but the IQ Batteries and IQ8 PV are only connected to the home and grid after the requisite entry service time period has elapsed. If Rapid Shutdown exit happens when the grid is not available, the home is immediately powered on via IQ Batteries and IQ8 PV. However, when the grid eventually comes back, the system waits for the requisite entry service time period before closing the Microgrid Interconnect Device (MID) relay to connect the home, IQ Batteries and IQ8 PV to the grid. c. Fixes an error which resulted in an “Exception occurred during execution” error being reported on the Enphase cloud administration portal in response to battery mode or tariff changes via the SITE_SETTINGS REST task. Note this error was only visible to Enphase internal personnel and had no effect on site functionality. d. Fixes an issue where retired IQ Batteries were mistakenly unretired. e. Fixes an issue wherein IQ Batteries were not discharging after a Zigbee range extender is provisioned on the system. f. Fixes an issue wherein PV production is set to 0 after a hardware-based power export limit is enabled and then cleared via Enphase Installer Platform. g. Grid profile is propagated after a timeout even if the DER relay (s) in the IQ System Controller are not closed. This helps in propagation of special grid profiles in systems where grid voltage/frequency are out of range of normal operation. h. Fixes an issue wherein USB failure errors are not cleared due to the IQ Gateway rebooting and the error persists unnecessarily on Enphase app. i. Improves recovery of Power Line Communication (PLC) between IQ Battery controller and IQ8X-BAT microinverters by automatically detecting loss of PLC to all micros and restarting the PLC stack, which then restores communication. j. Fixes an issue wherein redundant tariff tasks are issued to the system by the Enphase cloud. k. Fixes an issue where Very Low SoC (VLS) values, that can be set between 5% and 30% by homeowners in Enphase App, were sent to the IQ Gateway but were not successfully propagated to IQ Batteries. l. Fixes an issue in systems with generator integration where, after generator trips post a Low Voltage or Low Frequency Ride Through the system does not resume a microgrid with IQ Batteries and PV. m. Fixes an issue when post IQ Battery based system restart, at or below Very Low SoC (VLS) threshold, the batteries sometimes went to a Grid Tied state incorrectly and stopped forming a microgrid. n. Fixes an issue when the system transitions to Generator Mode with a generator connected, yet the IQ Battery incorrectly shows OFF Grid instead of Generator Mode. o. Fixes an issue with IQ Battery state toggling between ON Grid to Islanding to Grid Tied when Rapid Shutdown is initiated while the system is OFF Grid. This is seen in systems with IQ System Controller 2, IQ Batteries and IQ8 PV. p. Automatic recovery of IQ Battery from internal errors is improved to handle back-to-back power transistor driver faults. q. Fixes a rare issue where IQ System Controller settings did not change to the correct Multi Mode OFF Grid settings but stayed in a Grid Tied state during Low Voltage Ride Through (LVRT) condition. r. Fixes an issue where IQ Battery is not reporting normally, and reports issues post reconnection with IQ Gateway/Envoy S. s. Enhances protection features to prevent IQ Battery power transistor failures during IQ8X-BAT firmware upgrades. |
