S10 E home power station

Become independent from rising electricity costs

The energy market is constantly changing and consumers burdened by unforeseen price increases. The energy storage S10 is your tool for more independence from conservative energy suppliers and their demands.
This PV storage replaces, if necessary and at any time, the entire power system within your home*. The entire production is integrated, there is no need for additional inverters.
While the S10 MINI is primarily aimed for owners of small roof areas, the S10 E is designed for large roof areas.

*extra charge necessary for motor powered emergency switch

One system for 100% energy management
The home power station S10 decentralizes energy supply. It enables you for a locally energy production in your home, energy saving and self-determination for management. Here, the S10 also acts as an energy storage on its own energy and as a control center to its versatile use.
With integrated inverter and power storage function, the S10 home power station covers not only in daily use the entire energy needs of your home. Even in the event of a power failure your current continues - while the light remains off at your neighbors who do not own a S10.

Modular expendability
Smart ideas think beyond the first-best solution. Therefore, your S10 PV storage unit remains modularly expandable in the future. Thereby you are ideally prepared for tomorrow when issues such as e-mobility are becoming increasingly important.
Already available: the E-charging station for charging your wallbox type 2 capable electric vehicles.

 Good reasons for a smart investment
By investing in the S10 solar battery you will not only make a profitable investment and increase the value of your property. You mainly invest in your independence and the reliability of your own power supply.
Outstanding projects convince your heart and mind. All arguments for the installation of your home power station are based therefore, what you probably have long recognized: The future begins here.

S10 MINI house power plant

Your system for 100% energy management
The solar battery S10 MINI takes on the electricity supply in your house - and this in a compact design. Despite a small production facility can take care of himself and thus act autonomously.
The S10 MINI aimed it primarily at owners of small roof areas - for bigger roof areas of the S10 E power storage is intended.
It is through the own inverter power and secures the excess and makes this energy for individual consumption available again. By automatically detect power loss represents the S10 MINI within a fraction of a second on its own emergency power supply. The most necessary household appliances are still powered.

A leader in design and function

The S10 MINI sets standards in function and design. With compact dimensions of a by one meter and a timeless, shapely design, the PV-store fits perfectly into your home.
For simple design includes a touch display that essential functions can be easily controlled via the. All information about Solar power, battery charge level and the power supply are here easy to read, as well as the entire time series. An LED bar shows the energy management at first glance.

Modular expandability
Change your habits and thus your consumption behavior, additional batteries can be retrofitted. With the S10 MINI your own home remains future-proof and technologically up to date - you are already prepared for tomorrow.
Already available: the E-charging station for charging your wallbox type 2 capable electric vehicles.

Quattroporte - the modular power supply UNO, DUE, LINEA series

Energy storage for private, commercial and retrofitting

Modular power supply with the Quattroporte series from E3/DC
The Quattroporte-series devices are intended for flexible storage and self-consumption of self-produced electricity from PV systems and other energy sources. Due to the use of the Quattroporte series in an AC-controlled operation, the requirements for storing energy is the presence of grid-compatible alternating current. In the example of photovoltaic systems, this will be managed via an existing PV inverter. This makes the Quattroporte series especially suitable for the retrofit of existing PV systems.

The battery inverter, integrated within the AC current storage, converts the grid-compatible alternating current into direct current, which then can be stored in the batteries. If the battery is used for domestic consumption, the direct current is converted back to alternating current and distributed in the house as required.

The construction of the Quattroporte series is modular and can be adapted individually to your needs, whether as a private or a commercial customer. In every performance class and with every capacity.

The case has to be set up vertically and contains of four slots for compartments in which the individual modules of the Quattroport can be inserted next to each other and one above the other.

Battery modules of 6.5kWh per module are available with a maximum usable capacity in a single Quattroport case of 26kWh (4x modules). These cases can be combined as a complete system up to 78kWh (12x modules). Other systems can be expanded as required in energy farming.

All battery modules have an efficiency of up to 98% and have the latest lithium-ion battery technology. All systems can be retrofitted for an indefinite period, have no cycle limitation* and extremely low self-consumption (17 years in sleep mode until the battery is discharged).

The power to the grid is generated by individual battery inverter modules (2.0kW power). Up to 3 inverters (6,0kW power) can be generated in one Quattroport and up to 9 inverters (18.0kW power) in the Quattroporte system, one or two phases. More power can be expanded upon request within an energy farming.

Energy management
The connector module is the communication interface of the Quattroporte series through which the entire energy management takes place. The E3 / DC world is open, e.g. the use of the Wallbox, home automation and the complete portal world. The individual components of the Quattroport are connected via the connector module. There are four battery connections and three battery inverter connections. Through the Internet you can control the Quattroporte and the power generation. The external solar inverters are measured as well as the household consumption / commercial consumption.

Emergency power supply
The Quattroporte series supplies power in the event of a power failure at the battery inverter, in a separate mains connection, up to the power of the battery and until the battery is discharged. This means that there is an emergency power supply for selected consuming devices (one, two or three phases).

About us

Company details

Experience power for your home
Energy storage systems for the automotive industry
The development of energy storage systems for the automotive industry is the origin of E3/DC.
Vehicle to grid technology was founded by E3/DC in 2010 using complete vehicles from Volkswagen.
Technologies for self defined Home Energy Management
The E3/DC GmbH is an inverter manufacturer and was a spinoff of Wilhelm Karmann GmbH from Osnabrück. The vision of E3/DC are sustainable new energy standards for domestic homes with maximum performance and quality. The established technologies, coming from automotive electronics, provide renewable energies in the context of mobility, but also for other areas within the daily life. The name E3/DC is a connection of our mission: E3 (saving/einsparend, renewable/erneuerbar, effective/effektiv) and DC (direct current).

Proven quality of E3/DC
E3/DC has grown a network of >1.000 certified installers and nearly 9.000 installed storage systems in Germany (since 2012). They provide a sustainable quality and a regional coverage. More than 70 employees in three locations (Osnabrück, Wetter, Göttingen) are subject to rigorous quality and state of the art inverter control. The over 4.000 annually produced systems in Germany are in accordance with the ISO 9001 standards.

Shape your future
The development of E3/DC systems made an important contribution to the sustainable use of resources: Due to the storage and the use of solar energy itself provides maximum decentral and CO2 neutral independence from fossil fuels. This own power supply technology can bring you up to 100% renewable personal footprint. Our products offer innovative, pragmatic and reliable solutions and maximum flexibility in the future, by using state of the art connectivity and hardware interfaces – in mobility, heat technology and electrical home appliances.
