Hoymiles launches 22‑kW V2X charger

Hoymiles said on September 7 that it had launched a 22-kW bidirectional V2X DC charger that links directly with its HiOne all-in-one battery energy storage system, extending the company’s residential lineup from solar and storage into electric-vehicle charging. The company said the charger is meant to let solar panels, home batteries, EVs and the grid operate as a single system under one app-based platform.

The company said the unit delivers up to 22 kW of bidirectional charging power and is built for “seamless compatibility” with the HiOne All-in-One BESS. The HiOne-22VD-G3 product page says the charger enables bidirectional energy flow between an EV, the home and the grid. Hoymiles’ broader HiOne launch materials list the V2X charger as one module within a system that also includes inverter, battery, energy management, gateway and monitoring functions.

Hoymiles said the charger is DC-coupled, which means it can send power directly between photovoltaics, storage and the vehicle without relying on the car’s onboard charger for repeated DC/AC conversion. In its launch materials, the company said that setup reduces conversion losses during charging. (prnewswire.com) The product sheet says the charger supports a 200-1000 Vdc charging range. That voltage window, according to Hoymiles, is intended to cover both current and future EV platforms. ### What can homeowners do with it? Hoymiles said the charger allows an electric vehicle to act as an additional home energy resource. (hoymiles.com) In the company’s description, that includes charging the car from solar or stored electricity and sending electricity back from the vehicle to the house when needed. (tmcnet.com) The same release said the system is managed through the same app-based ecosystem used for the company’s home energy products, giving users a single interface for generation, storage, charging and household consumption. Hoymiles said that setup is aimed at backup power, self-consumption and grid interaction use cases. (w3oss.hoymiles.com) ### What does this add to Hoymiles’ product lineup? Hoymiles had already marketed AC EV chargers that could connect with its energy-storage inverters. The new launch adds a bidirectional DC option inside the HiOne platform, which the company presents as an integrated residential system. (eqs-news.com) Hoymiles says it was founded in 2012, has more than 2,200 employees and sells products in more than 190 countries and regions. The company describes itself as a solar and storage supplier focused on residential and commercial energy systems. ### What are the product-design questions behind a residential V2X box? (prnewswire.com) The published specifications point to several engineering constraints. A 22-kW bidirectional residential charger handling 200-1000 Vdc will need packaging for power electronics, thermal management and household installation limits, based on the company’s stated power level and voltage range. That is an inference from the product specifications, not a claim made by Hoymiles. (hoymiles.com) Hoymiles has not, in the materials reviewed, published detailed enclosure dimensions, cooling architecture or internal component layout for the charger. The company’s product page and launch release instead focus on system integration, bidirectional charging and compatibility with the HiOne platform. (hoymiles.com) ### Where does the launch go from here? Hoymiles has already posted the HiOne-22VD-G3 on its product site and included the charger in HiOne system materials published in early September. The next concrete step for buyers and installers is likely to come through regional availability, certification and model-specific installation documents on Hoymiles channels, which were not detailed in the materials reviewed on September 7.
