The IQ Bidirectional EV Charger goes beyond standard EV charging. It enables safe, reliable two-way power flow between the EV, home, and grid—sending power from the EV to the home during outages (V2H) and exporting from the EV to the grid when rates are high (V2G). Managed through the Enphase App, it intelligently switches between modes based on site conditions and homeowner preferences—turning the EV into a safe energy-sharing solution for the home.
AC power flow between the charger and home ensures added safety, while DC power flow between the charger and EV maximises efficiency. With integrated Dark Start technology, the charger delivers uninterrupted backup even during full grid outages. Designed for ISO 15118 standards and integrated with our globally compatible microinverters, the charger works with all bidirectional EVs, all grid profiles, and all types of homes, offering a reliable, future-ready solution backed by a 10-year warranty.

When integrated with an IQ Grid Switch, the charger can seamlessly transition between EV charging, home backup, and grid export functions even without a home battery. The scalable architecture allows for future system upgrades to include home solar and battery.
When integrated with the Enphase Energy System, the charger enables seamless home backup, maximum savings through AI Optimization and Self-Consumption modes that smartly manage charge and discharge algorithms.
Designed, tested, and built for performance
Engineered for durability and seamless interoperability. Enables quick and field-friendly installation.
Standards-based interoperability
Works with all ISO 15118-20 compliant EVs, CharIN and EVs testing to ensure global compatibility. Designed to meet IEC 62109, EN 50549 and VDE ARN 4105.
Seamless support for V2H, V2G
IQ Grid Switch functions as an islanding device to fully support both V2H and V2G applications, even when there is no home battery connected to the system.
GaN-based technology
Three 3.7 kW GaN-based microinverters provide support for 200 V–1,000 V DC power transfer between the EV and the charger hardware.
Integrated Dark Start
In case of an outage, the system instantly activates home backup (V2H) using the EV as a power source, maintaining electricity for essential loads.
Revenue grade metering
Meets MID specifications, with revenue-grade metering to ensure accurate monitoring and compliance across certified systems.
Easy serviceability
Designed to minimise service time through easily field-replaceable microinverters, cables, and related parts for faster, simpler maintenance.
The AI engine adjusts charge and discharge to maximise savings while meeting the homeowner’s preferred EV battery level at unplug time. It tracks real-time tariffs, solar production and home consumption forecasts, and grid status to manage charging and discharging behaviour.
Adaptive power flow with AI‐based control
The Enphase App optimises charging, backup, and export using intuitive software control.
Scales from smart charging to full energy independence
Supports key functionality on its own and expands seamlessly when paired with solar and battery.

FAQs
In AC bidirectional charging, bidirectional power conversion is handled inside the vehicle. In contrast, DC bidirectional charging, power conversion is handled inside the charger. Enphase will support both AC and DC bidirectional charging.
With DC bidirectional charging, the standards are finalised. With DC, seamless backup is supported and not vehicle dependent. DC bidirectional charging is also more efficient.
Yes. It can integrate with existing Enphase Energy Systems, unlocking home backup, smart charging, and grid services—depending on the site configuration and components present.
Enphase existing systems use system controller as grid interconnect device and our bidirectional charger will work seamlessly with it.
Future Enphase systems may be installed with IQ Grid Switch INT and IQ Meter.
The IQ Grid Switch INT represents a significant advancement in grid disconnection technology, designed to meet the evolving needs of distributed energy systems across Europe. As a next-generation Grid Interconnection Device (GID), this DIN rail-mountable solution is engineered to provide safe, reliable, and intelligent disconnection from the grid in both residential and commercial energy systems.
The charger is compatible only with EVs that are ISO 15118-compliant and support bidirectional power flow. It will not enable backup or export modes with non-bidirectional EVs, but standard DC charging will still function for compatible EVs.
No. The IQ Bidirectional EV Charger can provide backup and export functions, without a home battery, when used with the IQ Grid Switch. However, pairing with an IQ Battery enables full system flexibility and backup even when the EV is not plugged in.
The IQ Bidirectional EV Charger is expected to launch in late 2026.
