Germany is entering a decisive phase of electrification. As the nation accelerates the shift to electric mobility, EV charging is reshaping household and commercial consumption patterns. Heat pumps and other high-load devices are further pushing infrastructure toward higher peak demand.
To support grid stability, the §14a EnWG controllable-load policy enables grid operators to reduce user consumption during periods of grid stress in exchange for tariff benefits. This marks a fundamental transition: households now require smarter, more adaptive energy systems that can cooperate with the grid while minimizing their own electricity costs.
At the same time, Germany’s “solar peak” rules and the broader European Time-of-Use (TOU) pricing are moving energy management toward hour-level precision. Home storage is becoming the core device for energy scheduling, cost control, and grid interaction.
Swatten: Bringing Grid-Level Engineering “From Grid to Home”
Backed by 32 years of grid-level engineering expertise and extensive electric system projects in 100+ countries, Swatten integrates national-grid engineering standards into household and commercial energy systems. This includes millisecond-level load smoothing, high-precision power control, an intelligent BMS that manages charging curves, regulates cell temperature, and continuously adjusts charging and discharging current and power in real time. The system is fully ready for §14a load adjustments, supports automated TOU scheduling, and enables future participation in virtual power plants (VPPs). These capabilities help users reduce energy costs, increase self-consumption, and support overall grid resilience. With the government targeting one-third of all road transport to be electric by 2030, EV adoption is accelerating rapidly—driving the need for stable, high-power, intelligently managed home and commercial energy systems. Swatten’s product ecosystem is built precisely for this electrification path, with the 20 kW All-in-One system and the 50 kW three-phase hybrid inverter serving as core solutions.
The 20 kW All-in-One system integrates inverter, battery, EMS, BMS, AC charger, and intelligent load management into a single compact architecture. It supports direct solar-to-EV charging, delivers up to 30 kVA peak power, and uses high-safety LFP batteries with 100% DOD, enabling maximum usable capacity. Automated TOU scheduling and peak-shaving functions help households avoid high-tariff periods and mitigate short-term peak surges—an essential feature as EV charging and heat pumps become mainstream in German homes. Its compact design, high efficiency, and installer-friendly structure make it ideal for families transitioning into electrified living.
The 50 kW three-phase hybrid inverter, scalable up to 30 units in parallel (1.5 MW / 3 MWh), is engineered for microgrids, industrial parks, agricultural operations, and multi-family buildings. With outstanding three-phase imbalance tolerance, rapid grid-support response, high PV input capacity, and flexible AC/DC coupling, it ensures long-duration stability for peak shaving, TOU optimization, and complex C&I operating conditions—meeting Germany’s rising demand for large-scale electrification and intelligent load control.
Swatten’s unified peak-shaving and TOU optimization capabilities allow users to store energy during low-tariff periods and discharge or export during high-tariff windows, while avoiding cost spikes from high-load events such as EV charging or industrial equipment start-ups. With full readiness for §14a controllable-load requirements, Swatten systems maintain household and business stability even when the grid imposes temporary consumption limits—protecting user comfort while supporting national grid reliability.
Building a Safety and Intelligent European Energy Future Swatten’s vision is clear: to protect every kilowatt-hour with grid-level safety, empower users through intelligent energy control, and support Germany’s transition toward an electrified, renewable-driven future. Investing in safe and intelligent electricity is essential to building a secure energy future for all.
