Precautions
•No matter what the charging model is, once the temperature of the cell is above the absolute charging temperature, charging should be stopped.
• Please check the orientation of the positive and negative terminals before packaging.
•Connect the terminal or wire to the battery module, and pay attention to insulation to prevent short circuit.
• When not in use for a long time, the battery should be stored in a cool and dry place (<35°C, 30%~50% SOC, charge and discharge once every 3 months).
• Do not place the battery in direct sunlight or a heat source.
• Do not wear metal jewelry (such as rings, watches, accessories, etc.) when handling the battery unit.
Prohibited matters
Do not charge beyond the maximum charging rate.
Do not disassemble or modify the battery.
Do not throw or hit the battery.
Do not pierce the battery with sharp objects (such as nails, knives, pens, electric drills).
Do not mix with other types of batteries or modular units.
Do not excessively squeeze the battery during use.
Do not place the battery in a high temperature greater than 60°C.
Do not use conductive materials to connect the positive and negative terminals (such as metals, wires).
Bonjour,
Cela fait maintenant plus de 1 an que j'ai cette batterie.
Franchement aucun problème, l’équilibrage ce fait parfaitement et elle fonctionne très bien avec un onduleur sofar solar ME3000SP.
Merci Tewaycell
Je recommande sans hésitation.
Ich nutze das Tewaycell All-in-One System mit integriertem Wechselrichter und LiFePO4-Akku im privaten Bereich.
Positiv:
Die Anlage arbeitet zuverlässig und stabil. Die PV-Leistung wird sinnvoll genutzt, der Akku wird effizient geladen und im Alltag ist ein weitgehend autarker Betrieb möglich. Besonders positiv ist die übersichtliche Darstellung der Energieflüsse, sodass man jederzeit sehen kann, woher der Strom kommt und wohin er geht.
Neutral:
Der Akku lädt in der Praxis bis etwa 95–96 %, was technisch sinnvoll ist und der Lebensdauer dient. Auch die Ladeleistung ist systembedingt begrenzt, sodass bei hoher PV-Leistung nicht der gesamte Überschuss gespeichert werden kann.
Hinweis / Verbesserung:
Die verschiedenen Betriebsmodi (z. B. SBU, SOL, SNU) erfordern ein gewisses Verständnis. Die Funktionsweise ist korrekt, aber nicht auf den ersten Blick selbsterklärend. In meinem Fall kam es anfangs zu Missverständnissen in der Einstellung, die sich jedoch nach genauerer Einarbeitung klären ließen.
Eine ausführlichere oder praxisnähere Dokumentation der Einstellungen wäre hilfreich, um den Einstieg zu erleichtern und typische Fehlinterpretationen zu vermeiden.
Fazit:
Das System funktioniert technisch einwandfrei und erfüllt seinen Zweck sehr gut. Wer sich etwas mit den Einstellungen beschäftigt, kann die Anlage optimal nutzen. Für Einsteiger wäre eine bessere Dokumentation wünschenswert, insgesamt aber ein solides und leistungsfähiges System.
Had this unit up and working for around 3 months and its been flawless , Shipping was quite fast and packaging was fantastic. I'm using it at the farm it runs water pumps, lights power tools, a compressor and much much more. even runs a 2 stand shearing rig. The build quality and batterys are top notch. would recomend thes beauty without resevation.
Perfect and safe packing.
Very good usermanual. Very quiet ventilation fan. Easy settings possible.
Amaizing product! The delivery was smooth and quick. The battery took over everything without any issues whatsoever, bringing the energy consuption down by a lot. The customer support was also very helpful answering every question i had without any delay or attitude.
