Energy management system

Energy management systems (EMS) 

The Spelsberg Wallbox can be incorporated as part of an energy management system (EMS). The EMS controls all energy flows in the system, including PV systems, energy storage and loads. Thanks to intelligent control of the energy flows, in the ideal situation only self-generated energy is used as a supply. This significantly increases consumption from own sources and independence from mains power. Please refer to our compatibility list to find out which energy management systems the Spelsberg Wallbox is compatible with. List of compatible EMS.

Control via enabling contact

An auxiliary voltage of 15 VDC is applied to the PV-1 and PV-2 terminals in the Spelsberg Wallbox Smart Pro. The input is switched by connecting the two signals via a potential-free contact. The potential-free contact must be designed for <25 mA. Key switches or other types of switch can be used here. The relay contacts of a relay can also be used for switching whereby the relay itself can be triggered by a tariff changeover, building automation or similar.
