Taking a Holistic Approach to the Smart Home

Residential buildings are rapidly evolving into active, smart energy hubs. To maximize self-consumption rates and successfully implement sector coupling (heat, mobility, electricity), it is no longer sufficient to consider individual components in isolation.

 

Huawei FusionSolar Residential offers a perfectly coordinated ecosystem consisting of a inverter, scalable LUNA battery storage, energy management (SmartAssistant), and a smart charging infrastructure. As an official distributor, WATTKRAFT ensures broad market availability through strong wholesale partners and supports installers with hands-on training and first-hand technical support.

Benefits of Modern Photovoltaic Solutions for Residential Buildings

More Self-Consumption

Smart storage and energy management systems ensure that the solar power generated is used primarily within the household. The proportion of energy consumed on-site increases significantly, thereby reducing ongoing electricity costs.

Less power consumption

A properly sized PV system with battery storage significantly reduces dependence on the public power grid. Especially when grid electricity prices are high, a high degree of self-sufficiency pays off financially.

Future-Proof Scalability

Modular system architectures grow along with their users’ needs. Whether it’s additional storage, a new wallbox, or the integration of a heat pump: Modern PV systems are designed to be expanded.

Greater predictability

Those who control their own energy supply are less vulnerable to price fluctuations in the electricity market. A solar power system provides predictable energy costs and a solid foundation for long-term investment decisions.

Strong brands and tested components

WATTKRAFT sources products exclusively from well-known manufacturers such as Huawei, AIKO Solar, Canadian Solar, and Phono Solar. Certified quality, full manufacturer warranties, and reliable availability are a given.

Solar Power Systems for Installers, Distribution Partners, and Residential Projects

For installers, smart storage and energy management systems are a compelling selling point. They ensure that the solar power generated is used primarily within the homeowner’s own household. This significantly increases the proportion of energy consumed on-site and reduces ongoing electricity costs.

As a distribution partner, you’ll benefit from reliable supply chains, competitive terms, and a dedicated contact person. WATTKRAFT strengthens your portfolio with one of the most robust PV distribution offerings on the European market.

In the project business, technical expertise, on-time delivery, and bankable products are key. WATTKRAFT supports project developers and EPCs from system planning through component delivery, bringing extensive integration expertise to the table.

Housing companies and building operators can find scalable system solutions for tenant-generated electricity, charging infrastructure, and energy management at WATTKRAFT. Smart PV systems create added value for tenants and provide economic benefits for property owners.
