Hangzhou – September 17, 2026 -- Hoymiles has launched a DC V2X charger capable of delivering up to 22 kW, designed to plug directly into its HiOne All-in-One home battery system and let electric vehicles double as backup power sources for the house.
The charger lets EVs power homes during outages
Using Vehicle-to-Home (V2H) technology, the device can supply backup electricity when the grid goes down. It also supports Vehicle-to-Grid (V2G) functions, allowing households to help reduce peak demand and participate in virtual power plant programs. A built-in MID-certified meter tracks energy use for accurate monitoring.
Direct DC charging cuts energy loss and charging time
Unlike AC chargers that rely on a vehicle's onboard charger to convert AC to DC, Hoymiles' V2X sends DC power straight from solar panels and battery storage to the car, skipping that conversion step. The company says this reduces energy losses during charging.
At its 22 kW peak, the charger adds roughly 110 kilometers of range per hour, compared to about 35 kilometers per hour with a standard AC charger, according to Hoymiles. The system is built to work with 95% of mainstream electric vehicles.
The unit is rated for outdoor installation near parking spots
The standalone charger carries IP65 water resistance and IK10 impact protection, allowing installation next to a parking space independent of where the HiOne battery unit sits. Owners manage the V2X through the same app used for Hoymiles' solar and storage products, choosing between a green-energy mode and a fast-charging mode depending on their needs.
The launch extends Hoymiles' home energy ecosystem, which already links solar generation, battery storage and energy management, into electric mobility.
