Leading US-based microinverter manufacturer Enphase Energy unveiled its latest bidirectional electric vehicle (EV) charger, IQ Bidirectional EV Charger, at RE+ 2025.  

As the name suggests, in addition to its primary purpose as an EV charger, it also supports vehicle-to-home (V2H) and vehicle-to-grid (V2G) functions, once paired with the vehicle charging port. The V2H mode, which converts stored energy to AC power, serves as the emergency backup for homes during a power outage or failure, while V2G enables export of stored energy to the distribution grid. These features are enabled by pairing it with an external device, called IQ Meter Coller. Among the 2 types of EV chargers, AC and DC, the former depends on the vehicle’s on-board chargers, while the latter directly connects with the vehicle’s charging port. Enphase opted for the DC route. 

Equipped with a gallium nitride (GaN) based microinverter, this charger can deliver up to 11.5 kW of power to charge 400 V or 800 V battery-based EVs. In the V2H mode, the charger provides emergency backup power to connected critical home loads, thanks to the grid-forming functionality of the built-in microinverter. Embedded with artificial intelligence (AI) based algorithms, this system can schedule vehicle charging or discharging according to real-time electricity rates and a roof-mounted PV installation’s generation forecast. According to the company, these functions, which lead to savings for homeowners, are automatically managed in real-time by its software – the Enphase App.  

Enphase Energy senior vice president of the digital business unit Jayant Somani said, “The IQ Bidirectional EV Charger brings the family car into the home energy system.” He added, “It’s simple to install, easy to control, and designed to deliver backup power and the ability to share energy with the grid for homeowners.” 

The company expects to make this charger commercially available globally in the second half of 2026.
