The German residential solar market is on the cusp of significant change with the introduction of the SolarEdge ONE Controller device
The SolarEdge ONE Controller for Residential Solar Systems
- SolarEdge Technologies, Inc. (Nasdaq: SEDG) is a global leader in smart energy technology, with a focus on delivering innovative solutions for residential and commercial customers
- Germany’s new §14a EnWG regulation is opening the market to smart integration of controllable loads by the utility
- The regulatory challenge is complex, requiring the integration of SolarEdge’s residential solar systems with leading third-party EV chargers and heat pumps
Benefits of the ONE Controller
The SolarEdge ONE Controller offers a simple solution to the complex regulatory challenge, enabling residential installers to commission solar and storage systems that can integrate with the home’s Smart Meter system (iMSys) in-line with regulatory requirements. The device has been tested by EEBUS e.V. in its Living Lab in Cologne, and has been found to comply with the use cases required by §14a EnWG.
Compliance with Regulatory Requirements
The ONE Controller complies with the use cases required by §14a EnWG, enabling residential installers to commission solar and storage systems that can integrate with the home’s Smart Meter system (iMSys) in-line with regulatory requirements. This compliance ensures that grid security management requirements from grid operators are fulfilled, while homeowners can benefit from reduced energy bills through smarter energy management.
Integration with Third-Party Equipment
The ONE Controller also serves as an interface for the SolarEdge Home ecosystem with industry-leading third-party EV chargers, such as specific models from ABB, MENNEKES, and Wallbox, and heat pumps from Vaillant. Other heat pumps can be controlled through SG-ready compatibility**.
Future-Proofing with Smart Energy Management
The ONE Controller enables homeowners to benefit from smart energy management, reducing energy bills and increasing energy efficiency. The device also helps to future-proof customers as the energy landscape shifts towards more dynamic electricity tariffs.
Availability and Support
Residential solar installers can find more information on the ONE Controller on SolarEdge’s booth (Stand 110, Hall B4) at Intersolar 2025. The device is available for order now, and expected to be available in Q3 2025.
