“Fill” your car for free with the E3/DC-Wallbox

The home power station supplies the communication-enabled E3/DC wallboxes with the available solar energy, which in turn means that you can charge your electric car at home free of charge. The sun does not charge you for refueling!

Solar charging has priority

E-mobility offers high potential for saving and independence

In combination with the home power station, the Wallbox can charge precisely according to the user’s wishes: exclusively or primarily with solar power, or as quickly as possible also with mains power. At 22 kW, the maximum charging current provided by the Wallbox ensures rapid charging at home. However, if you only want to use your own electricity to charge your vehicle, the charging current is reduced to the PV power that is currently available.

Charging can be regulated in such a way that other direct consumption in the home and recharging of the battery do not go short. On the other hand, volumes of electricity in the storage, that are not needed for other purposes, thanks to the promise of a sunny day, can be used to charge your car. In terms of performance and capacity, the S10 E PRO home power station is even designed to recharge your car regularly overnight, from the battery, supported by the Wallbox. After all, not everyone has the option of simply hopping on a bicycle when the weather is fine.

Connections for all types of vehicles

Products with special qualities

With the proven E3/DC Wallbox, installation and networking have already been significantly simplified, the new Wallboxes multi connect and multi connect II also offer even better functionality for purely solar charging: Because both wallboxes can automatically switch between single-phase and three-phase charging, depending on the power currently available from the PV system. This means that even weak solar radiation can be used for mobility.
Both E3/DC wallboxes have an industrial quality standard and intelligently contribute to a high degree of self-sufficiency. The E3/DC wallboxes are mounted where it is most convenient according to local conditions – on the wall or also with a stand, in the garage or under a carport.

Of course, there is practically no restriction for E3/DC customers in their choice of electric car, because the wallboxes can be used in their factory configuration for refueling most electric vehicles and many plug-in hybrid vehicles.

E3/DC was awarded two seals of approval by EUPD Research in the wallbox sector: E3/DC was again named “TOP BRAND WALLBOX” in 2022 on the basis of a survey of installers. In addition, a large-scale survey of prosumers also led to a special recommendation of the E3/DC brand in the wallbox segment.


Output of up to 22 kW

The Wallbox charges Type 2 and Type 1-compatible electric vehicles and many plug-in hybrid vehicles, with an AC output of up to 22 kW.

Team players in the area of energy management

The E3/DC can be used to load solar power, either primarily or exclusively. To do so, the charging current is reduced to the available PV power.


Via software updates for the home power station, future models of electric vehicles will also be supported, according to the IEC 61851.
