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.

Beispielhaftes Sparpotenzial mit dynamischem Stromtarif
€ 0 / year
Solar panels only (without storage)
Solarstrom wird direkt im Haushalt genutzt. Überschüsse stehen am Abend jedoch nicht mehr zur Verfügung oder fließen ins Netz.
€ 354 / Jahr
Solar Modules + Sunpura S2400
Überschüssiger Solarstrom wird tagsüber gespeichert und später genutzt – ideal für mehr Eigenverbrauch am Abend.
€ 788 / Jahr
Sunpura S2400 AC+ Dynamic Tariff
Der S2400 kann günstige Strompreiszeiten besser nutzen und gespeicherte Energie bereitstellen, wenn Strom teurer ist.

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 your stored solar power when grid electricity is most expensive. Increase your savings potential by combining the system with a time-of-use electricity tariff

Berechnungsgrundlage: Based on an 1800W system with S2400, an electricity price of £0.40/kWh, and a 20-year lifespan. Additional gains from dynamic tariffs are estimated. Actual savings may vary depending on the region and system.

No more waste: The intelligent SUNPURA S2400 AC system

Why waste energy? The Sunpura Meter monitors your consumption in real time and automatically stores any surplus in the battery. Enjoy complete energy independence and lower electricity bills thanks to perfect control.
