The EV Charger Business from SMA Solar Technology AG - home and fleet charging with solar smarts

The EV Charger Business from SMA Solar Technology AG sits on a garage wall like a quiet white brick, cables neatly looped, waiting for the next company car to plug in. When the connector clicks into place, you hear a short relay snap and know the system is working with your rooftop solar, not against it.

What the EV Charger does

SMA's EV Charger Business is designed for small commercial sites and larger homes that already run SMA solar inverters and an SMA Home or Commercial Manager energy controller. It delivers up to 22 kW AC charging, supports three-phase operation, and automatically modulates power to match available solar output and building load.

Product manager Jörg Krause describes it as a bridge between the PV system and the company parking lot, because the charger can prioritize solar surplus first and then grid power. In practice, that means a pool car fills mainly when the roof is producing, smoothing load peaks and improving self-consumption ratios for the building.

Smart energy management on site

The charger works hand in hand with the SMA Sunny Home Manager or SMA Data Manager M, using real-time data to avoid overloading the grid connection while still charging cars reliably. With dynamic load management, it can distribute charging power among several units so that multiple vehicles can be connected without tripping breakers.

Facility managers see the effect directly in the SMA Energy app or web portal, where charging sessions appear alongside PV generation and building consumption. That visual coupling makes it easier to explain to staff why charging is faster at noon on sunny days and slower on cloudy evenings, which is crucial for user acceptance in shared fleets.

Load management and fleets

The EV Charger Business targets company fleets, guest parking and mixed-use sites where several cars may arrive within a short window. With up to 16 chargers networked and controlled via SMA energy management, charging can be staggered so that priority vehicles, such as service vans, receive more power than long-stay staff cars.

This is particularly useful in markets with demand charges, where short, high peaks in electricity draw can increase costs significantly. By flattening these peaks, SMA's charger and controllers help keep operating costs more predictable, a practical selling point for small and medium-sized enterprises shifting their fleets to electric.

Installation and everyday use

Installers mount the EV Charger Business on a solid wall or stand, connect it to three-phase supply, and integrate it via Ethernet with the SMA data manager and inverter network. In many installations, the unit's housing feels robust and slightly textured to the touch, giving drivers a stable base as they wrap and unwrap the cable several times a day.

For drivers, operation is simple: plug in, authenticate if required, and let the system handle charging based on building conditions. LED indicators show the charging state, while the app or portal provides more detailed information, such as current charging power and estimated completion time.

Strengths and limits

A key strength of the EV Charger Business is its deep integration into SMA's PV and storage ecosystem, which ensures coordinated control between solar generation, battery storage and charging load. This alignment avoids the need for third-party load management systems in many cases, reducing overall project complexity.

On the flip side, that tight coupling means the charger makes the most sense on sites already committed to SMA's inverter and energy management platform. For mixed-brand installations or standalone chargers for public roadside use, other solutions may be more flexible, especially where open roaming and complex payment backends are required.

Where it fits in SMA's strategy

SMA Solar Technology has been positioning itself less as a pure inverter manufacturer and more as a system provider for comprehensive energy management. CEO Jürgen Reinert repeatedly emphasizes that future growth will come from digital services and sector coupling, linking electricity, heat and mobility.

The EV Charger Business sits precisely in this sector coupling story, turning PV systems into fuel pumps for electric cars rather than just feed-in machines for the grid. For installers and building owners, this broadens the business case for solar beyond pure kilowatt-hour production, adding workplace charging as a concrete use case.

Context and SMA shares

For SMA Solar Technology, EV charging solutions complement its strong European base in residential and commercial PV, where regulations increasingly favor self-consumption and smart load management. The EV Charger Business adds a tangible mobility angle that can deepen customer relationships across hardware and software.

SMA Solar Technology shares (ISIN DE000A0DJ6J9) trade on Xetra, providing investors with liquid exposure to this mix of solar inverters, storage and EV charging solutions without a direct bet on car manufacturers themselves.
