System­ architectures for every performance­ class

Scalable photovoltaic and BESS solutions for Residential, C&I, Utility, and charging­infrastructure
Every grid topology and load profile requires specific engineering. As a leading value-added partner and a pioneer of Huawei from the very beginning, WATTKRAFT offers cross-technology system solutions. From smart Residential systems developed in cooperation with wholesale providers to complex grid-forming installations in the megawatt range: We guarantee maximum system efficiency and LCOE optimization—all from a single source.

Harnessing the Sun's Full Potential

Solar energy doesn’t end with generation. It is only through the intelligent interplay of photovoltaics, energy storage, and energy management that we can use available energy as efficiently as possible. “Making the Most of Every Ray” sums up this approach—and at the same time describes our commitment to creating holistic solutions that get more out of every ray of sunlight.

Customized PV system­architectures
by application area

Site-Specific
Engineering

Whether it’s a high-demand commercial property with significant base load requirements, a logistics center designed for zero net metering, or an open-field solar plant with a medium-voltage connection: WATTKRAFT designs system solutions that are precisely tailored to the site’s energy and structural requirements.

From string topology
to the energy­ system

We don’t think in terms of individual components, but rather in terms of holistic energy ecosystems. We support EPCs and project developers in scaling projects from connected C&I rooftop systems to highly complex Utility-scale plants, including transformer integration.

System Integration &
Interoperability

The cost-effectiveness of a system depends entirely on the communication between its components. As an experienced system integrator, we ensure seamless interoperability between Huawei’s SUN2000 inverters, scalable BESS storage systems, charging infrastructure, and overarching energy management (SmartAssistant).
