The Energy Independence Revolution Is Here
Rising electricity prices, unpredictable grid outages, and the global push toward renewable energy have made home energy storage no longer a luxury — it's a smart investment. Whether you're running a solar-powered home, managing a small business, or simply want reliable backup power, the right energy storage system can transform how you consume and pay for electricity.
Tewaycell 30KWh All-in-One ESS is engineered for exactly this moment.
What Is the Tewaycell 30KWh All-in-One ESS?
The Tewaycell 30KWh All-in-One Energy Storage System combines a 51.2V 600Ah LiFePO4 battery pack with a built-in 12KW three-phase hybrid inverter into a single, compact unit. No separate inverter cabinet, no complex wiring — just one integrated system that's ready to power your home or business.
Key Features That Set It Apart
🔋 LiFePO4 Chemistry — Built to Last
Unlike conventional lithium-ion batteries, LiFePO4 (lithium iron phosphate) cells offer superior thermal stability and safety. The Tewaycell ESS is rated for 6,000+ charge cycles at 80% depth of discharge — that's over 16 years of daily cycling. A built-in active balancer module and temperature-sensitive fire extinguisher add an extra layer of protection.
⚡ 30kWh Large Capacity & 12kW Three-Phase Power: Unmatched Load Capacity
Power and capacity are the core indicators of an energy storage system, and this Tewaycell model excels in both aspects.
Equipped with a 30kWh large-capacity battery pack (51.2V, 600Ah), it can easily support the full daily power consumption of large houses and villas. In case of a complete grid outage, it provides stable continuous power supply for more than 24 hours, covering air conditioners, water heaters, kitchen appliances, lighting systems and home entertainment equipment all at once. For remote off-grid cabins and farms, it acts as a permanent reliable power source to get rid of noisy, high-fuel-consumption generators.
The built-in 12kW continuous three-phase pure sine wave inverter supports AC 380V output, with a peak power reaching 24kW.
☀️ Dual MPPT Solar Charging
Two independent MPPT charge controllers (up to 9,000W each) allow you to connect multiple solar panel strings simultaneously, maximizing your solar harvest even in partially shaded conditions. MPPT voltage range: 200–650Vdc.
🕐 Time-Slot Charging & Discharging
One of the standout features is the intelligent peak/valley tariff scheduling. Program the system to charge from the grid during off-peak (cheap) hours and discharge during peak (expensive) hours — automatically reducing your electricity bill without any manual intervention.
🔌 Four Charging Modes
Choose from solar-only, mains priority, solar priority, or mixed PV + grid charging — giving you full flexibility to optimize for cost, sustainability, or reliability depending on your situation.
🔗 Expandable Capacity
Need more storage? The system supports parallel connection with additional units of the same model, making it easy to scale your energy storage as your needs grow.
In addition, rich communication interfaces including RS485, CAN, USB and dry contacts are reserved. The optional WiFi remote monitoring function allows you to check real-time data such as battery voltage, current, remaining capacity and system operating status via mobile phones or computers anytime, anywhere.
Who Is This For & Where Does It Fit?
Thanks to its large capacity, high three-phase power, diverse working modes and easy installation, this 30kWh all-in-one ESS fits a wide range of scenarios:
- Large family homes and villas: Daily power supply and emergency backup against blackouts
- Off-grid cabins, farms, ranches and remote rural areas: Independent power supply without relying on the public grid
- Solar homeowners: Maximize self-consumption and reduce grid dependency
- Guesthouses, retail shops and small commercial workshops: Stable power guarantee for daily operation
- Small businesses: Cut electricity costs through peak shaving
- EV owners: Charge vehicles using stored solar energy overnight
- Regions with frequent power failures: Professional UPS uninterrupted power protection
