Designed for maximum flexibility and real requirements. *The expansion depends on the capacity of your electrical house connection. Please consult a certified electrical specialist before installation.
100% compatible with existing PV systems

Kleiner kraftvoller Speicher

Kleiner kraftvoller Speicher. Ordentliches Gehäus.
Das einzige was negativ auffällt sind seitlichen Klappen. Öffnen sich ständig.
Ansonsten voll zufrieden. Zeitnahe Erfassung der Stromwerte und schnelle Reaktionszeit. Macht was er soll.
