In the era of renewable energy and sustainable living, energy storage plays a critical role in ensuring a stable and efficient power supply. Whether you’re powering your home with solar panels or supporting a commercial energy system, having a reliable, safe, and scalable battery is essential.
The MASON 280L LiFePO4 Battery Pack is designed with exactly that in mind — offering outstanding performance, safety, and flexibility.
The Seplos MASON 280L battery is designed for users who need a reliable LiFePO4 energy storage solution with intelligent battery management and flexible system expansion options.
Built for Versatility
The MASON 280L is engineered for both residential and commercial energy storage applications. As a complete Seplos MASON kit solution, the system integrates battery cells, enclosure design, and smart BMS technology to simplify installation for solar energy storage projects. It is assembled with 16 high-quality 3.2V 280Ah lithium iron phosphate (LiFePO₄) cells in a 16S1P configuration, paired with the intelligent SEPLOS Smart BMS (Battery Management System).
With 14.336 kWh of rated energy and the ability to connect up to 16 units in parallel, it’s easy to scale your storage capacity as your needs grow.
This scalable design makes the Seplos battery suitable for homeowners, installers, and system integrators looking for expandable solar energy storage systems.
Smart Battery Management
- At the heart of the MASON 280L is its advanced BMS, which constantly monitors:
- Voltage – 16-cell sampling with ±20mV accuracy
- Temperature – Multiple sensors for cell, ambient, and MOSFET temperatures
- Capacity & Cycle Count – Real-time estimation with ±5% accuracy
- Historical Data Logging – Stores up to 500 records for easy troubleshooting
This smart system enables balanced charging, protects against unsafe operating conditions, and extends the battery’s lifespan.
The integrated BMS continuously monitors battery conditions, helping maintain stable performance and improving long-term reliability in residential and commercial applications.
Comprehensive Protection Features
- The MASON 280L offers multi-layer safety:
- Over-voltage / Under-voltage protection (cell & pack level)
- Over-current protection for charging & discharging
- High / Low temperature protection
- Short circuit protection with automatic recovery
- Intelligent recovery protocols for safe restart
- User-Friendly Indicators
Applications
The SEPLOS MASON 280L is ideal for:
- Home Solar Energy Storage – Store excess solar power for nighttime use
- Commercial Backup Power – Prevent downtime during grid outages
- Off-Grid Power Systems – Reliable energy in remote areas
Why It Stands Out
With high capacity, long cycle life, and smart safety features, the MASON 280L is not just a battery — it’s a long-term investment in energy independence. For solar installers and energy storage providers, the Seplos MASON 280L provides a practical battery solution that balances performance, safety, and installation flexibility.
Its combination of advanced BMS technology, robust LiFePO4 chemistry, and scalable design makes it a top choice for forward-thinking energy storage solutions.
Conclusion:
As the demand for renewable energy and reliable backup power continues to grow, choosing the right battery system is crucial. The SEPLOS MASON 280L (3.0) offers the perfect balance between performance, safety, and flexibility — empowering homes and businesses to take control of their energy future.
