SolaX Power recently introduced its Binary Series vehicle-to-home (V2H) system at Intersolar Europe 2026, presenting an AC-side approach to bidirectional charging for residential solar and storage applications.
The system is designed to connect a compatible electric vehicle with rooftop PV, home battery storage, and household loads. It enables the vehicle to charge from solar or grid electricity, and to discharge energy back to the home when required, depending on vehicle capability and system configuration.
SolaX describes the Binary Series as the industry’s first AC-side V2H solution. The company bases the claim on an architecture that separates AC charging from controlled DC discharging, rather than treating EV charging and home energy supply as a fully coupled process.
The system’s BRY-A22D7 bidirectional EV charger supports adjustable AC charging from 1.4 kW to 22 kW and controlled DC discharging for residential use. The design is intended to support daily EV charging while adding home energy functions such as solar self-consumption, peak-load reduction, and backup support.
Across Europe, more households are combining solar PV, batteries, heat pumps, and electric vehicles. These systems are often installed at different times and managed through separate devices or applications. As a result, the value of residential energy systems increasingly depends on coordination rather than on individual hardware alone.
“For residential V2H, the question is not only how much power a charger can move,” says James Li, Assistant to the General Manager and Marketing Director at SolaX Power. “It is whether the system can be fitted into real homes, used reliably every day, and managed in a way that respects the vehicle battery. That is the starting point for our AC-side design.”
The Binary Series allows the EV charger and inverter to be installed up to 50 meters apart, so installers have more flexibility in homes where the parking space, garage, utility room, and energy storage system are not located together.
During discharge, the system coordinates the vehicle-side output, V2H charger, and storage inverter while operating within vehicle-defined limits. It is designed to support household loads without treating the EV battery as an unrestricted energy source.
The system forms part of SolaX’s wider PV, storage, charging, discharging, and heat-management platform. At launch, it is designed to work with SolaX X1-VAST and X3-G4 Pro hybrid inverters, with support for X3-Ultra planned.
SolaX has also integrated the home battery and V2H charger into a single application, allowing users to view system status, energy flows, and charging or discharging settings from one platform.
