SolaX XHub Becomes First Chinese-Brand HEMS in Living Lab Cologne's EEBUS Pilot-Qualified EMS Category

SolaX has announced that its XHub home energy management device has been listed as EEBUS pilot-qualified on the Living Lab Cologne EEBUS device list in Germany. The device appears under the EMS – Energy Management System category and, according to the current public list, is the first home energy management system from a Chinese brand to be included in this category. XHub supports Limitation of Power Consumption (LPC), Limitation of Power Production (LPP) and Monitoring of Power Consumption (MPC).

For households, the listing means something quite practical. XHub can support three basic tasks that are becoming important in Germany's residential energy market: reduce power demand when required, limit PV output when the grid asks for it, and provide power data so the system can see whether devices have responded.

LPC allows power consumption to be reduced in a grid-compliant way. In a home, this can apply to flexible loads such as wallboxes, heat pumps or battery charging. It is one of the mechanisms used to support §14a EnWG, which deals with controllable household loads.

LPP allows power production to be limited when required. For a PV and storage system, this means the inverter or other generation-side equipment can respond to feed-in or generation control requirements. This is relevant to §9 EEG and to grid areas with high levels of distributed solar.

MPC provides real-time power measurement data. This data can be used by the EMS, smart meter infrastructure or grid-side systems to check current power flows and close the loop between control and response. For homeowners, it also makes device-level energy use easier to see in the SolaX app.

Taken together, these three functions are a foundation for a home energy controller in Germany. They allow XHub to receive grid-related instructions, coordinate devices in the home and provide the data needed to confirm what is happening.

EEBUS is an open, manufacturer-independent communication standard for energy devices. It helps energy management systems, control boxes, smart meter infrastructure, EV chargers, heat pumps, PV systems and battery systems exchange information without each device needing its own separate integration path.

As part of the SolaX residential energy solution, XHub can connect hybrid inverters, battery storage, EV chargers, heat pumps, the SolaX app and cloud platform. For households, this means a solar-plus-storage system can become part of a wider home energy setup. For installers, it provides a clearer route to connect different devices within one system.

“Home energy management is becoming the link between the household and the grid,” said SolaX's Head of Smart Energy Platform. “By supporting LPC, LPP and MPC, XHub can help homes manage consumption, generation and power data in one place. That is becoming increasingly important as PV, batteries, EV charging and heat pumps are installed together.”

SolaX said the listing supports its work in the European residential market, where homes are becoming more active participants in the energy system. The company will continue to develop XHub as part of its platform for PV, storage, e-mobility and heating applications.

Note:
The EEBUS pilot-qualified status of XHub is based on the information shown on the Living Lab Cologne / EEBus Initiative e.V. public device list.

Product compatibility and feature availability may vary depending on device version, firmware version and project configuration.
