Bidirectional energy made smarter with AI
Predictive intelligence meets scalable design for seamless energy control.
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 maximizes efficiency. With integrated Black Start technology, the charger delivers uninterrupted backup even during full grid outages. Designed to 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.

FAQs
In AC bidirectional charging, power is exchanged over the AC, with bidirectional power conversion handled inside the vehicle. In contrast, DC bidirectional charging uses a dedicated DC interface, with power electronics outside the vehicle and as part of the charger to manage the conversion. The choice between AC and DC impacts vehicle complexity, charger complexity, installation costs, reliability, and regulatory compliance—making it a critical design decision for both EV manufacturers and energy system providers.
Yes. The IQ EV Charger 2, available in the second half of 2025, will support AC bidirectional functionality. The IQ Bidirectional EV Charger, launching in 2026, will support DC bidirectional functionality.
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.
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, high-power 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 Meter Collar. 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 2026.
