Bidirectional EV Chargers: Complete Guide To V2G & V2H (2025)
Comprehensive guide to bidirectional EV chargers. Compare top models, installation costs, compatible vehicles, and real ROI. Updated for 2025 with latest products.
A bidirectional electric vehicle charger is an advanced EV charger that can both charge and discharge energy from an EV battery. With unidirectional (one-way) EV chargers, electricity flows just from the power grid into the vehicle.
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. Is the IQ Bidirectional EV Charger compatible with existing Enphase Energy Systems? Yes.
After years of promises, bidirectional chargers are starting to reach the market, but availability remains limited, and costs are high. According to a 2023 study by the Smart Electric Power Alliance (SEPA), compared to one-way EV chargers, “the price premium was between $8,500 and $9,000” for residential bidirectional charging systems.
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).
