What are the differences between the Heidelberg Wallbox Home Eco and the Heidelberg Wallbox Energy Control?
Most significantly, the Heidelberg Wallbox Energy Control has a communication interface (RS485). This permits (1) dynamic load management at the charging point and (2) the use an external control unit: It is possible to interconnect several Energy Control units, which can then control themselves, creating a self-contained, static charging system that intelligently distributes the charging capacity between the connected Wallboxes. The Wallbox Energy Control can be connected to an external energy management system (HEMS). This allows for functionalities like charging with surplus power from a solar power system. Beyond these functional differences, the Heidelberg Wallbox Energy Control indicates its status and any errors not with an LED at the side like the Wallbox Home Eco, but using the front light. In addition, the Heidelberg Wallbox Energy Control comes with a stainless steel frame.
