Hoymiles HiBattery 4020 S – 4 kWh Erweiterungsspeicher für die HiBattery 4020 X

Der Hoymiles HiBattery 4020 S erweitert dein bestehendes 4020-X-System um zusätzliche 4 kWh (4.020 Wh) Kapazität. So speicherst du noch mehr Solarstrom und überbrückst auch Abende, Nächte und verbrauchsstarke Tage – für maximalen Eigenverbrauch und mehr Unabhängigkeit vom Netz.

Einfach stapeln – modular bis 16 kWh

Der HB-4020-S wird werkzeuglos auf die HiBattery 4020 X gestapelt. Mit bis zu drei Erweiterungsakkus baust du dein System auf bis zu 16 kWh aus. Dank Balancing auf Modulebene gleicht das System den Ladestand neuer Akkus automatisch aus – du kannst auch Jahre später ohne Leistungsverlust erweitern.

Wichtiger Hinweis: Erweiterungsakku, kein eigenständiger Speicher

Der HiBattery 4020 S ist als Zusatzakku für die HiBattery 4020 X konzipiert und besitzt keinen eigenen Wechselrichter. Für den Betrieb ist eine HiBattery 4020 X als Basis erforderlich.

Gleiche Sicherheit & Langlebigkeit wie die 4020 X

  • LiFePO4-Zellen (314 Ah), ≥ 8.000 Ladezyklen, über 15 Jahre Lebensdauer
  • 10 Jahre Garantie
  • Schutzklasse IP66, Betrieb von −20 °C bis +55 °C, integrierte Heizung
  • Hoymiles BMS mit 48 Schutzfunktionen, Aerosol-Brandbekämpfung und Überdruckventil

Wann lohnt sich die Erweiterung?

Immer dann, wenn deine 4 kWh abends nicht mehr ausreichen – etwa bei größerem Haushalt, Wärmepumpe oder E-Auto. Mehr Kapazität bedeutet, dass weniger Solarstrom ungenutzt ins Netz fließt und du einen größeren Anteil selbst verbrauchst.

Häufige Fragen

Kann ich den 4020 S allein betreiben?

Nein. Er ist ein Erweiterungsakku ohne eigenen Wechselrichter und benötigt eine HiBattery 4020 X als Basis.

Wie viele Erweiterungsakkus kann ich anschließen?

Bis zu drei – damit baust du die Kapazität von 4 kWh auf bis zu 16 kWh aus.

Muss ich beim Erweitern neu verkabeln?

Nein. Der Akku wird einfach gestapelt; der Ladestand wird automatisch ausgeglichen.

Comfortable and stays cool
Color: White-cooling Basic, Size: Queen(Pack of 1)
Great pillow. When i opened it, i noticed a strange smell, i assumed its the smell of whatever they use to make the pillow stay cool. You have to fluff it for a good amount of time to make sure the cooling agent spreads well in the foam. Is what i assumed atleast. Its a perfect amount of softness for me. Pair it with some bamboo pillow cases and you got a good night of sleep

Comfortable and Supportive, but Adjust the Filling
Color: White-cooling Basic, Size: Queen(Pack of 2), Color: White-cooling Basic, Size: Queen(Pack of 2)
I’m very happy with this pillow. The size is big and it feels soft while still providing good support, perfect for midnight scrolling on TikTok. One thing to keep in mind is that it can feel a little too tall if you use all of the filling that comes with it. The good news is that you can easily adjust the amount of filling to find the height that works best for your sleeping position. Once I customized it, it was much more comfortable. Overall, great quality, comfortable, and worth the purchase.

BEST PILLOWS EVER!!!
Color: White-cooling Basic, Size: Queen(Pack of 2)
I am very picky with my pillows because I have a bad neck and I can never seem to find a good pillow. But I tried this pillow because it had everything I was looking for and the price was great! You get two of them and they are absolutely awesome.! normally I would need to lay on two pillows to try and get comfortable but with these pillows I just lay on one and I wake up with no neck pain. They really have a nice cooling effect. They actually puff up immediately after opening them. All you have to do is just shake them up and the pillow just puffs straight up.. It comes with extra cushioning if you want it to make it firmer and if you don’t want it as firm as it is, you can actually take some out. It really is such a beautiful pillow. It’s perfect in every way to me being such a picky pillow person. You just lay your head down on it and it forms around your neck and your head and when you get up, it goes right back to its normal form. It doesn’t get flat and I love it. I completely recommend this to anyone who is a person who has a hard time finding a really good pillow.

Top of the line, best pillows Ive ever had
Color: White-cooling Basic, Size: Queen(Pack of 2)
These pillows are top of the line! I bought them in 2024 and they are still fluffy. When they lose a little fluff, you just punch em around a little bit and voila, like new again. They have kept their shape cery well and do great for cooling. I haven't had to add more filling yet either. I just laid my head on one and thought, I need to do a review cause everytime i lay on these pillows its like clouds. My head is heavy and this is relief :-D
