Intelligent charging modes for all situations

The intelligent charging modes of the SMA eCharger adapt to the needs of the user with forecast-based operation. It switches phases automatically, allowing charging during low solar power periods for cost-effective mobility, higher PV self-consumption and faster PV system amortization.

By harnessing both grid and PV power, the SMA eCharger charges a vehicle twice as fast as standard wallboxes while adhering to grid regulations.

Benefits

Convenient: forecast-based operation learns the behavior and needs of the users and offers a choice of charging modes
Cost-efficient: optimized mode charges the car with PV surplus
Time-saving: fast mode charges the car quickly

Targeted charging

Your car is conveniently and reliably charged according to your specifications.

Charging with PV surplus

Preferentially charges your car with solar power, making it particularly affordable and sustainable.

Fast charging

Combines PV and grid power to charge your car particularly quickly.

Automatic phase-switching for most efficient use of solar energy

The new SMA eCharger makes the most of the power of the sun. With automatic phase switching, EVs can be charged with self-generated energy even during periods of low solar power generation.

Your customers’ benefits

Unbeatable cost-effective mobility: Charging with 100% solar energy is considerably cheaper as compared to charging from the grid
Significant increase in the PV self-consumption rate
Sustainable: Avoid CO₂ emissions compared to charging from the grid
Faster amortization of the PV system

Automatic phase-switching for most efficient use of solar energy

FAQ

When will the SMA eCharger be available?

The SMA eCharger is being delivered to SMA trading partners since the end of August 2024.

How do I get an offer for the new SMA eCharger in combination with a complete PV system, including battery storage system?

As an installer, you can order the SMA eCharger from a local distributor of SMA solutions in those countries where the inverter is available.

If you are a private customer, please enquire with an installer of solar solutions in your area.

How long is the warranty period for the SMA eCharger?

The SMA Limited Factory Warranty period for the SMA eCharger is five years.

Can I operate several SMA eChargers in one system?

Yes, up to three SMA eChargers can be operated in combination with the Sunny Home Manager 2.0.

Can the SMA eCharger also be operated in combination with the SMA EV Charger 7.4/22?

Yes, mixed operation of the SMA eCharger and SMA EV Charger 7.4/22 in combination with the Sunny Home Manager is also possible. In total, up to three SMA charging stations are supported in so-called multi-EVC operation.

Can I retrofit my PV system with the SMA eCharger?

Most PV systems can be retrofitted with an SMA eCharger to take advantage of the many benefits of PV-optimized charging of electric vehicles. The prerequisite is that a Sunny Home Manager 2.0 already exists or is retrofitted with the wallbox installation.

What subsidies are available for charging stations?

Many federal and local governments have their own incentive programs for PV systems in general and charging stations in particular. We advise you to enquire with the administration of your country or region.

I do not own a Sunny Home Manager 2.0. Can I still use the SMA eCharger?

The SMA eCharger was developed for use with the Sunny Home Manager 2.0. This configuration also allows you to use intelligent charging management. But even without the Sunny Home Manager 2.0, the SMA eCharger can be operated as a stand-alone wallbox and visualized in Sunny Portal powered by ennexOS and SMA Energy App. A later integration into a PV system is thus possible.

The SMA EV Charger 7.4/22 has a charging mode selector switch for local activation of fast-charging mode. Can I also activate fast charging locally on the SMA eCharger?

Yes, instead of a switch as with the SMA EV Charger 7.4/22, fast charging with the SMA eCharger is activated locally by tapping twice on the interaction surface on the device and visualized on the integrated display. In addition, the charging mode can be changed via the SMA Energy App. In contrast to the SMA EV Charger 7.4/22, it is possible to switch from any charging mode to any charging mode without restrictions.

My SMA eCharger has been installed at a location that can also be accessed by third parties. How can I prevent possible charging by unauthorized third parties?

The SMA eCharger has an integrated RFID card reader. You have the option of using the access management function to train RFID cards/tags to authorize charging processes on the device - such as the RFID cards included in the scope of delivery. In this case, the SMA eCharger is blocked when an electric vehicle is connected. Charging only takes place after successful authorization with a previously trained RFID card on the interaction surface of the device.

Is my vehicle compatible with the SMA eCharger?

At market launch, the SMA eCharger supports charging in accordance with IEC 61851-1 Mode 3. All electric vehicles that have implemented this standard can be charged with the SMA eCharger. This applies to most vehicles available in Europe.

The SMA eCharger is supplied without a charging cable. Where can I get a compatible charging cable?

SMA offers type 2 mobile AC charging cables in lengths of 5.0 m, 7.5 m and 10.0 m as accessories. Of course, the type 2 charging cable supplied with the vehicle can also be used for charging.

The SMA eCharger has a type 2 charging outlet instead of a permanently connected charging cable. Do I now have to get the cable out of the trunk every time and stow it away again?

With the type 2 charging outlet, you benefit from maximum flexibility. The charging cable can also be permanently locked/connected to the SMA eCharger via the SMA Energy App and thus behaves like a permanently connected charging cable. You can also swap the charging cable independently if, for example, a vehicle with a type 1 charging connection is to be charged or the situation requires a longer charging cable.

Does the SMA eCharger have a calibrated meter?

At market launch, the SMA eCharger does not have an MID meter compliant with calibration law. The SMA eCharger has an integrated energy meter. The measuring accuracy is +/- 1 %. If your application requires an MID-compliant energy meter, you can also integrate one into the wallbox supply line.

SMA is planning a new hardware version of the SMA eCharger with certified MID/calibration law compliance of the wallbox. In addition, there will be a software update for all SMA eChargers that enables integration into the SMA eMobility Portal using the OCPP protocol.

Is the SMA eCharger suitable for bidirectional charging?

At market launch, the SMA eCharger supports unidirectional AC charging of electric vehicles in accordance with IEC 61851-1. The international standard ISO 151118-20 for bidirectional AC charging of electric vehicles is currently being finalized. Subject to the final standardization and regulatory framework, SMA plans to offer a chargeable eProduct for the SMA eCharger in the future in order to use the discharge of the vehicle battery for V2X applications in combination with compatible electric vehicles.

Are there special training courses for the SMA eCharger?

The SMA Solar Academy offers extensive practical seminars and webinars on the SMA Home Energy Solution. Of course including SMA eCharger.
