TB Series Residential Lithium Energy Storage Battery

TB Series Residential Lithium Energy Storage Battery

High-Capacity 51.2V LiFePO4 Battery System with Parallel Scalability & Multi-Inverter Protocol Support

The Toyomax TB Series (10.24kWh – 20.48kWh) is a high-performance 51.2V Lithium Iron Phosphate (LiFePO4) energy storage battery designed for home energy management, grid-outage backup, and light commercial applications. Built with premium cell chemistry and a heavy-duty metal enclosure, the TB Series offers long cycle life (≥6000 cycles), high round-trip discharge efficiency (≥98%), and deep depth-of-discharge capabilities. Featuring multi-protocol compatibility, integrated BMS protection, and support for up to 16 units in parallel, it provides scalable power independence for residential solar systems.

Key Features

  • High-Safety LiFePO4 Chemistry: Built with stable Lithium Iron Phosphate cells that eliminate combustion and thermal runaway risks under high impact, overcharge, or short-circuit conditions.
  • Long Cycle Life: Delivers over 6,000 cycles at 80% Depth of Discharge (DOD), providing long calendar life and lower lifetime cost of ownership compared to traditional lead-acid batteries.
  • High Parallel Scalability: Supports up to 16 units connected in parallel to scale overall energy capacity up to 327.68kWh for large residential or commercial microgrids.
  • Multi-Inverter Protocol Support: Seamlessly integrates and communicates via CAN/RS485 protocols with major hybrid and off-grid inverter brands.
  • Lighter & Compact Build: Weighs approximately 40% of an equivalent lead-acid battery array, offering easier floor-standing installation with integrated caster wheels.
  • High Discharge Power: Delivers twice the discharge power of traditional batteries while maintaining steady voltage stability under heavy load surges.
  • Smart System Diagnostics: Features built-in LCD status displays with optional Wi-Fi and Bluetooth communication modules for real-time monitoring.
