Bidirectional charging lets your electric vehicle do more than draw energy from the grid—it can send stored energy back out. The three most common forms are:
- Vehicle-to-Load (V2L): plug small appliances or tools directly into the car’s onboard outlet (1.5–2.4 kW on most EVs).
- Vehicle-to-Home (V2H): the EV powers your whole house through a certified bidirectional charger and transfer switch during an outage.
- Vehicle-to-Grid (V2G): the EV exports power to the utility during peak-demand events and can earn bill credits or payments.
Enphase’s upcoming IQ Bidirectional EV Charger (expected in 2026) is built around the same microinverter-based architecture Pinnacle already installs. Highlights from Enphase:
- Up to 11.5 kW bidirectional AC power flow between the EV, home, and grid.
- Managed through the Enphase App, switching automatically between charging, V2H backup, and V2G export.
- Integrated Black Start for instant home backup during grid outages.
- Designed to ISO 15118-2 and 15118-20 standards and supports OCPP 2.1.
- Works with the IQ Meter Collar for whole-home monitoring and grid-agnostic V2H/V2G operation.
- Scales with Enphase solar and IQ Battery storage for a complete home energy system.
Other manufacturers are moving the same direction. As of mid-2026, V2H-capable EVs include the Ford F-150 Lightning, GM’s Ultium lineup (Chevrolet Silverado EV, Blazer EV, Equinox EV, GMC Sierra EV, Hummer EV, and Cadillac Lyriq/Escalade IQ/Vistiq/Celestiq), the Tesla Cybertruck with Powershare, the Kia EV9 with Wallbox Quasar 2, the Volvo EX90 and Polestar 3 with dcbel Ara, and CHAdeMO-generation Nissan Leaf systems. Many more brands are expected to add certified V2H/V2G hardware through 2026–2027.
Why this matters for homeowners with solar + storage. Pairing a bidirectional EV charger with rooftop solar and a home battery turns your car into an additional energy reservoir. During an outage, your EV can keep essential circuits running. When utility rates spike, stored solar or EV energy can offset costs. Over time, V2G programs may even pay you for helping stabilize the grid.
How Pinnacle can help. We already design and install solar panels, battery storage, Tesla Powerwall, and electrical service upgrades. Adding an Enphase bidirectional charger is a natural extension of that integrated approach. We evaluate your panel capacity, recommend the right charger and interconnection path, and coordinate with your utility so the system is safe, code-compliant, and ready for future V2G programs.
