IQ Gateway software version 8.2.4498 introduces support for the IQ Relay Kit (SKU: IQ- RELAY-E2-US) and IQ Battery 5P in grid-tied (without backup) for single-phase 208 V configuration.

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

#	Feature	Description
1	Introduces support for IQ Battery in grid-tied (without backup) for single-phase 208 V configuration	Adds single-phase 208 V support for IQ Battery 5P in grid-tied configurations for California.
2	Introduces support for IQ Relay Kit (SKU: IQ-RELAY-E2- US)	Supports IQ Relay Kit (SKU: IQ-RELAY-E2-US). IQ Relay isolates the IQ Series Microinverters from the grid when it detects voltage differentials or loss of grid connection. It also automatically reconnects to the grid when the grid condition returns to normal.
3	Improvements to IQ Gateway access point (AP) mode	Enhances the auto-enable logic in IQ Gateway software for AP mode, to facilitate Wi-Fi reconfiguration by both homeowners and installers.
4	Improvements to the Enphase Mobile Connect cellular modem recovery	Enhances the IQ Gateway software's recovery logic for Enphase Mobile Connect cellular modem when there is no internet connectivity via the cellular network.

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:

#	Feature	Description
1	Introduces 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.
2	Introduces 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.
3	Supports 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.
4	Improves 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
5	Faster 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.
6	Improves 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.
7	Bug 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.
