Beispielrechnung: Mehr Eigenverbrauch mit dem Sunpura S2400
Vergleichen Sie, wie ein Balkonkraftwerk mit Speicher Ihren Solarstrom besser nutzbar macht – vom direkten Verbrauch bis zur intelligenten Nutzung dynamischer Stromtarife.
Warum sich der Unterschied zeigt
Der wirtschaftliche Vorteil entsteht nicht nur durch mehr Speicher, sondern durch die bessere Abstimmung von Solarstrom, Verbrauch und Strompreis.
Mehr Eigenverbrauch
Gespeicherter Solarstrom wird häufiger im eigenen Haushalt genutzt, statt ungenutzt ins Netz zu fließen.
Nutzung nach Sonnenuntergang
Energie vom Tag steht auch abends, nachts oder bei schwächerer Erzeugung zur Verfügung.
Dynamische Tarife nutzen
Bei passenden Stromtarifen kann das System günstige Preisfenster besser ausnutzen.
Use stored solar energy when grid electricity costs more. Increase potential savings by combining the system with a compatible time-of-use tariff. dynamic electricity tariff
Why battery storage can make a decisive difference
- Only 30% of the generated electricity is used at home
- Surplus solar power may be exported when it has relatively little value
- Higher electricity costs in the evening and overnight
- Continued reliance on the grid
- No backup power during a power cut
- Up to 80% of the generated electricity is used at home
- Surplus energy is stored for the evening and overnight
- Use lower-cost and self-generated energy more effectively
- Greater energy independence
- Backup power available during a power cut
S2400 or S2400 AC — which solution is right for you?
Choose the right battery solution for starting a new solar setup or adding storage to an existing system.
For new Solar and battery systems
- Store solar energy directly
- Simple way to get started
- With PV input for new Setups
- Greater flexibility without rebuilding the entire system
For existing rooftop or plug-in solar systems
- Add battery storage to an existing system
- AC-coupled expansion
- Ideal for an existing solar panel system
- Greater flexibility without rebuilding the entire system
Choose the right battery storage solution
Both systems support compatible metering, time-of-use tariffs and intelligent energy management. The main difference is the type of solar installation they are designed for.
S2400
Battery storage with direct solar input for a new solar setup
S2400 AC
AC-coupled battery storage for an existing solar system

FAQ
Was bringt a Solar and battery system?
A solar and battery system helps you use more of the electricity generated by your solar panels at home. Surplus energy is stored for later — for example in the evening or when household demand is higher — helping to increase self-consumption and reduce grid imports.
Who benefits most from battery storage?
Battery storage can be particularly useful for homes that generate solar electricity during the day but use more energy in the evening. It may also suit households that regularly export surplus solar and want to increase self-consumption.
How do I add battery storage to a compact solar system?
It depends on your system. The S2400 includes direct PV input and is designed for new compact solar-and-battery setups. The S2400 AC is AC-coupled and designed to add battery storage to an existing solar panel system. UK installation, grid-connection and compatibility requirements must be checked for the exact configuration before purchase.
Was is the Unterschied zwischand S2400 and S2400 AC?
The main difference is how each system is used. The S2400 is designed for a new setup with direct PV input. The S2400 AC is an AC-coupled solution for adding battery storage to an existing solar panel system. Both use LiFePO4 technology, start with 2.4 kWh of capacity and can integrate with the Sunpura smart energy ecosystem.
Can I add battery storage to my existing solar system?
Yes. The S2400 AC is designed as an AC-coupled solution for existing solar panel systems. It allows battery storage to be added without replacing the complete solar setup, subject to system compatibility and UK installation requirements.
Can ich With the system dynamic electricity tariffs use?
Yes. With compatible monitoring and control equipment, the system can schedule charging and discharging around time-of-use or dynamic electricity tariffs. Available functions depend on the system configuration, tariff, data source and device compatibility.
Do I need a compatible energy meter?
Not necessarily for basic battery operation, but compatible energy monitoring is often needed for more precise automation. It can help the system understand household imports, exports and consumption, and make better use of suitable time-of-use tariffs. Confirm compatibility with the UK meter and installation before purchase.
Is the system modular expandable?
Yes. Sunpura battery systems use a modular design. Depending on the configuration, the S2400 can be expanded up to 9.6 kWh, allowing capacity to grow if household energy use changes.
Which battery chemistry is used?
Sunpura uses LiFePO4 battery chemistry, selected for long service life, stability and everyday home energy storage. Product specifications also list IP65 protection and high cycle life.
Muss ich ein Balkonkraftwerk mit Speicher in Deutschland anmelden?
Ja. Steckersolargeräte müssen grundsätzlich im Marktstammdatenregister (MaStR) registriert werden. Die Bundesnetzagentur hat die Registrierung seit dem 1. April 2024 vereinfacht. Für Steckersolargeräte gelten zudem aktuell Sonderregelungen bis 2.000 W Modulleistung und 800 VA Wechselrichterleistung.
Wie groß darf ein Balkonkraftwerk in Deutschland aktuell sein?
Für Steckersolargeräte gelten nach den Sonderregelungen derzeit bis zu 2.000 Watt installierte Modulleistung und 800 VA Wechselrichterleistung pro Entnahmestelle. Wenn mehrere Geräte hinter derselben Entnahmestelle betrieben werden, werden sie zusammengerechnet.
Gibt es Förderungen für Balkonkraftwerke mit Speicher?
Das hängt stark von Bundesland, Stadt oder regionalen Programmen ab. Einheitliche bundesweite Aussagen ändern sich häufig, deshalb solltest du aktuelle Fördermöglichkeiten immer direkt bei deiner Kommune, deinem Bundesland oder den örtlichen Stadtwerken prüfen. Für die FAQ selbst ist es am sichersten, keine pauschalen festen Zuschüsse zu nennen, sondern auf die regionale Prüfung hinzuweisen. Diese Fragelogik taucht auch in Wettbewerber-FAQs häufig auf.
Will the battery work in winter or at low temperatures?
The system is designed for everyday use and the product specifications list a wide operating-temperature range and IP65 protection. Actual winter performance still depends on temperature, solar irradiance, installation and the overall system configuration.
Is a solar and battery system difficult to use?
The system is designed to make home energy storage easier to understand and manage, with app control and compatible monitoring accessories. UK installation and grid-connection requirements still apply and should be checked before purchase.
