Tewaycell 16kWh 51.2V 314Ah LiFePO4 Battery for Home Energy Storage
Tewaycell 16kWh 51.2V 314Ah LiFePO4 Battery delivers approximately 16.08kWh of energy for home solar storage, backup power and off-grid systems. Available in 51.2V and 48V configurations, with multiple capacity and output options to meet different residential energy storage needs.
Key Features
16kWh High-Capacity Energy Storage — The 51.2V 314Ah LiFePO4 battery provides approximately 16.08kWh nominal energy, ideal for home solar energy storage, backup power and off-grid applications.
Multiple Voltage Options — Available in 51.2V and 48V configurations to match different home energy storage systems and inverter requirements.
Long-Lasting LiFePO4 Chemistry — Built with high-quality LiFePO4 battery cells, offering excellent cycle life, stability and reliable performance for daily residential energy storage.
Active Balancing – 2A BMS-integrated balancing for the EU Warehouse version or a built-in 5A active balancing module for the China Warehouse version.
Up to 15 Units in Parallel — Expand your home energy storage system by connecting up to 15 compatible LiFePO4 batteries in parallel. Scale your total storage capacity for solar energy storage, backup power and off-grid applications as your energy needs grow.
Safety Protection — The built-in condensed aerosol fire suppression device provides an additional layer of safety, helping suppress potential thermal events within the battery system.
Wide Inverter Compatibility — Supports CAN, RS485 and RS232 communication and is compatible with many popular solar inverter brands, including Deye, Growatt, GoodWe, Victron, Sofar and more.
Air Switch Options — The 100A BMS version includes a built-in Air Switch. Due to internal space constraints, the 200A BMS version does not have a built-in Air Switch, but an external Air Switch can be added for circuit isolation and protection.
【Note】：If you want to connect products in parallel, it is recommended to order them all at once, because products purchased at different times use different batches of lifepo4 cells. In this case, when connecting them in parallel, the product differentiation will be relatively obvious.

Frequently Asked Questions
Q: Is this battery compatible with my inverter?
A: The Tewaycell 16kWh LiFePO4 Battery is a 51.2V low-voltage (LV) battery system designed for 48V-class hybrid inverters with a battery input range of approximately 40V–60V.
Before ordering, please confirm:
✅ Your inverter supports 48V/51.2V lithium battery systems
✅ Your inverter supports compatible CAN or RS485 communication protocols
The battery is compatible with many mainstream inverter brands, including Growatt, GoodWe, Deye, SofarSolar, Victron, Voltronic, SRNE, Megarevo, PYLONTECH, SMA, Solis, MUST, TBB, Studer, and more.
⚠️ This battery is not compatible with high-voltage (HV) inverter systems requiring battery voltages above 100V.
Please contact us with your inverter brand and model before purchase if you're not sure, and we will confirm compatibility.
Q: What is the difference between the China Warehouse and EU Warehouse versions?
A: The main difference is the balancing solution. The EU Warehouse version features 2A BMS-integrated balancing, while the China Warehouse version includes a built-in 5A active balancing module.
Q: Can I connect multiple batteries in parallel?
A: Yes. Up to 15 compatible LiFePO4 batteries can be connected in parallel, allowing you to expand your total home energy storage capacity for solar, backup and off-grid applications.
Q: What is the difference between the 51.2V and 48V battery versions?
A: The main difference is the nominal system voltage and available capacity configurations.
Q: What is the difference between the 100A BMS and 200A BMS versions?
A: The main difference is the maximum current capability and output power. The 100A BMS version is suitable for systems with lower power requirements and includes a built-in Air Switch. The 200A BMS version supports higher-current applications and up to 10kW output, depending on the selected configuration and inverter.
Due to internal space constraints, the 200A BMS version does not include a built-in Air Switch, but an external Air Switch can be installed.
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.
