Was ist Refurbished beim BK215?
Der SunLit Balkonkraftwerkspeicher BK215 in der "Refurbished"-Version bietet Ihnen eine hochwertige und preiswerte Alternative zu einem brandneuen Gerät. Dieses aufgearbeitete Produkt wurde bereits einmal verkauft und aus verschiedenen Gründen zurückgegeben – beispielsweise aufgrund von Fehlbestellungen oder spezifischen Kompatibilitätsbedürfnissen. Nach der Rücksendung wurde der BK215 sorgfältig geprüft und instand gesetzt, um die gleiche Funktionalität wie ein neues Gerät zu gewährleisten.
Was bedeutet "Refurbished"?
Wenn wir ein Produkt als "Refurbished" kennzeichnen, bedeutet dies, dass es bereits in Gebrauch war, aber durch unsere Fachtechniker gründlich überprüft und wieder in einen Zustand versetzt wurde, der den Neugeräten entspricht. Es funktioniert zu 100% einwandfrei, es kann jedoch sein, dass leichte Gebrauchsspuren sichtbar sind. Diese Spuren sind rein kosmetischer Natur und beeinflussen die technische Leistung des Speichers nicht.
Ihre Vorteile auf einen Blick
- Qualitätsgesichert: Jeder BK215 wird nach strengen Standards getestet, um sicherzustellen, dass er voll funktionsfähig ist.
- Preiswert: Refurbished Produkte sind preislich günstiger als neue Modelle und bieten somit eine kosteneffektive Lösung.
- Umweltfreundlich: Durch den Kauf eines aufgearbeiteten Gerätes tragen Sie dazu bei, die Umweltbelastung zu verringern, da weniger Ressourcen für die Herstellung eines neuen Produkts benötigt werden.

4. Does the Storage Have a Bypass Function?
Yes, the storage system is equipped with a bypass function that operates under the following conditions:
-
Full Bypass State (Charging Only):
When the input power is greater than or equal to twice the output power, the storage is charged but not discharged. All grid power is supplied through the input, and the storage system remains in a full bypass state.
-
Full Bypass State (Discharging Only):
When the output power is greater than or equal to twice the input power, the storage is discharged but not charged. All input power is fed to the grid, and the storage system remains in a full bypass state.
-
Partial Bypass State:
If neither condition 1 nor 2 is met, but both input and output power are greater than 0W, the storage system operates in a partial bypass state.
5. Can I Manage the Feed-In Power of the Balcony Power Plant Storage?
