What It Is

1KOMMA5° is a German clean-energy solutions provider that offers households a one-stop energy system covering everything from consultation and installation to maintenance. Its core selling point is using Heartbeat AI to connect solar PV, heat pumps, home battery storage, Wallbox EV chargers, and Dynamic Pulse dynamic electricity pricing, automatically optimizing the home's energy flow and the timing of electricity purchases.

Core Capabilities

Based on the main text, Heartbeat AI is the hub of the entire system. Drawing on renewable energy supply and dynamic pricing, it purchases and stores electricity during low-price periods and coordinates heat pump operation and EV charging. The product modules include the Solaranlage (solar PV system), Wärmepumpe (heat pump), Stromspeicher (energy storage), and Wallbox. 1KOMMA5° also emphasizes "Alles aus einer Hand"—meaning local consultation, installation, and maintenance services are provided by a regional Meisterbetrieb.

Pricing & Business Model

The website does not disclose standardized packages or software subscription prices; it only mentions a €2,500 discount for a "solar system + heat pump" combination. With Dynamic Pulse dynamic pricing, electricity can drop as low as 0 Cent/kWh during certain periods when renewable energy is abundant, but the text also notes that costs may rise in autumn and winter. As a result, actual costs depend heavily on hardware configuration, household electricity usage patterns, regional installation conditions, and electricity price fluctuations.

Pros & Cons

The strength lies in the tight integration of hardware, installation services, and smart scheduling, making it well suited for households that don't want to integrate solar PV, heat pumps, storage, and pricing services on their own. Its local service network and customer case studies also enhance its credibility. The downside is that there is little information on the enterprise-software dimension: there's no mention of APIs, permission management, team collaboration, data compliance, or third-party SaaS integration. In addition, the savings from dynamic pricing are not a fixed return.

Who It's For & Access from China

It is better suited to households in Germany and Europe, especially homeowners looking to lower electricity bills, replace oil and gas heating, and install solar PV and EV charging facilities. For Chinese enterprise-software buyers, it is not a general-purpose SaaS but a home energy platform. The main text provides no information on access from mainland China, so this is rated as unknown.
