Success Stories: How Our Users Optimize Their Energy Systems

How much potential is really hidden in your home? We followed five users who use their HEMS (Home Energy Management System) in their daily lives. These real-world examples show how you can drastically reduce your electricity costs and increase your independence with the right app control.

🚗 Florian: Driving the Mobility Transition with a Dynamic Tariff

Florian proves that a high household consumption of 4,000 kWh and electric mobility are a perfect match. He powers his 5-person single-family home with a 12 kWp PV system and a 10 kWh battery storage.

His secret advantage: A dynamic tariff. The intelligent control system ensures that his EV (approx. 2,000 kWh demand for 10,000 km/year) charges preferentially when the sun is shining or market prices are at their lowest.

• The result: An effective kilowatt-hour price of less than 24 cents for residual electricity.

• The benefit: He drives his EV for an unbeatable €2.59 per 100 km and achieves an autarky of 78%. The energy manager saves him €336.60 annually.

💧 Heiko: Maximum Efficiency for Hot Water and EV Charging

In Heiko's semi-detached house (3 people), everything revolves around the coupling of electricity, mobility, and heat. With a household consumption of 2,800 kWh, he uses a 9 kWp system and a 10 kWh battery storage. Despite a static tariff of 30 cents, he gets the maximum out of his system.

Especially clever: The integration of his domestic hot water heat pump (500 kWh annual demand).

• The result: His hot water is heated 90% with PV power – costing him only €4.25 per month.

• The benefit: The EV is charged 85% with surplus. Overall, his autarky is 16% above the standard values of common PV calculators. The energy manager brings him a gain of €264 per year.

☀️ Silke: High Self-Consumption – Without a Battery

Silke shows that you can achieve enormous independence even without a physical battery storage. She uses a 7 kWp system for her terraced house (3 people, 3,000 kWh consumption). Since she has a gas heating system, she uses an immersion heater to store excess energy directly as heat.

• The result: Despite lacking a battery, she hits a self-consumption rate of over 85%.

• The benefit: Thanks to a dynamic tariff, she drives her EV for €3.20 per 100 km. Particularly impressive: From May to August, her hot water is prepared almost entirely for free via the immersion heater. The app control saves her €280 annually.

🏠 Michael: The Heat Pump as the Heart of Autarky

Michael uses his large roof area of 18 kWp to tame the heating costs for his 4-person house (household consumption 3,000 kWh). He does without a battery and instead relies on direct sector coupling with his heat pump.

• The result: The intelligent control system shifts loads so skillfully that the heat pump is operated 46% with pure PV power.

• The benefit: His heating costs are only €57 per month. The EMS provides 14% higher autarky than standard configurations and an additional saving of €277 per year.

🔋 Daniela: Maximum Sector Coupling in a Single-Family Home

Daniela's system is fully equipped: A 14 kWp system, a 10 kWh battery storage, a heat pump, and an EV power the 4-person household (3,500 kWh base consumption). With a static tariff of 28 cents, the app serves as the central brain.

• The result: Although she heats, drives an EV, and powers the entire household, her residual electricity costs are only approx. €100 per month.

• The benefit: Through the perfect coordination of all components, she saves over €300 per year additionally thanks to the energy management system.
