  #	Feature	Description
  1	Bug fixes	Fixes the issue of multiple USB unplugged events observed in the Enphase Installer Portal. Fixes the issue of microinverters, batteries, and other devices not reporting status by improving the Zigbee communication. Fixes the issue of the Battery Management Unit (BMU) shutting down whenever the IQ battery is idle. Fixes the issue of undesirable power consumption (tare loss) by the battery when in idle state. Fixes the issue of IQ Battery maximum state-of-charge (SoC) being limited to 97% instead of 100%. Fixes the issue of Phase Imbalance Management (PIM) getting enabled for single-phase systems.

   

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

IQ Gateway software version 7.6.346 supports new microinverters and battery products for Sweden, Denmark, South Africa, and India. This release enables Consumption CT-based phase imbalance management (PIM) as the default method for complying with phase balancing requirements.

• Gateways supported: IQ Gateway Metered

• Countries: Sweden, Denmark, South Africa, and India

• Microinverters supported: IQ8 Series Microinverters (IQ8MC-72-M-INT, IQ8AC-72-M-INT, IQ8HC-72-M-INT, IQ8P-72-2-INT), compatible third-party string inverters

• IQ Battery supported: IQ Battery 3T/10T

• Supported system configurations:

  • Grid-tied solar and storage systems with IQ8 Series Microinverters, IQ Gateway Metered, and IQ Battery 3T/10T for Sweden and Denmark

  • Grid-tied solar and storage systems with compatible third-party string inverters, IQ Gateway Metered, and IQ Battery 3T/10T for Sweden and Denmark

  • Grid-tied Solar Only systems with IQ8 Series Microinverters and IQ Gateway Metered for Sweden and Denmark

  • Grid-tied Solar Only systems with IQ8HC and IQ8P Microinverters and IQ Gateway Metered for South Africa

  • Grid-tied Solar Only systems with IQ8P Microinverters and IQ Gateway Metered for India

  #	Feature	Description
  1	IQ8HC and IQ8P Microinverter support	Supports IQ8HC and IQ8P Microinverters with IQ Gateway Metered for South Africa. Supports IQ8P Series Microinverters with IQ Gateway Metered for India.
  2	IQ Battery support	Supports IQ Battery 3T/10T along with IQ8 Series Microinverters for Sweden and Denmark.
  3	Compliant with phase balancing requirements in Sweden and Denmark to ensure imbalance between phases is below the allowed limit	Supports Consumption Current Transformer-based PIM for three-phase systems. 3.68 kVA PIM requirement is supported as specified in section A.3 of EN 50549-1:2019 for Denmark and Sweden. Note: M Series Microinverters and compatible third-party inverters are not controllable by an IQ Gateway. IQ Gateway does not support PIM and power export limiting for these inverters.
  4	Bug Fixes	Fixes the issue of continuously triggering AC disconnect due to phase imbalance. Fixes the issue of IQ Battery maximum state-of-charge (SoC) being limited to 97% instead of 100%. Fixes the issue of solar production dropping to zero until the IQ Gateway is rebooted. Fixes the issue of IQ Battery exporting to grid when load is turned off with PIM active. Fixes the issue of solar power production stopping after turning on dynamic phase imbalance limiting.

   

  The following known issues have been observed in IQ Gateway software version 7.6.346:

  Known issues:

  #	Feature	Description
  1	PV production stops randomly for sites with a standard IQ Gateway	PV production stops whenever a grid profile with power Export Limiting or PIM is enabled at a site with a non-metered IQ Gateway. This issue will be fixed in upcoming software releases.
  2	A large spike in consumption is reported in the Enphase App when the IQ Gateway software is upgraded to v7.6.346 from v7.6.168	The Enphase App reports a huge spike in consumption whenever the IQ Gateway software is upgraded to v7.6.346 from v7.6.168. Enphase mitigates this by deleting the records of that day for the system owner, thereby ensuring system owner-facing energy consumption figures are not affected.
