SMTE Pylontech US3000C 3.5kWh 48V LiFePO4 Lithium Battery – Rack-Mount Energy Storage

Power your home, business, or solar energy system with the Pylontech US3000C 3.5kWh 48V LiFePO4 Lithium Battery. Engineered with proprietary Lithium Iron Phosphate chemistry and an intelligent Battery Management System (BMS), this modular energy storage unit delivers 3.5kWh of clean power with an enhanced 95% Depth of Discharge (DoD) and over 6,000 cycles. Designed for standard 19-inch server rack mounting or modular bracket stacking, it features multi-protocol CAN/RS485 communication, self-cooling silent operation, and backward compatibility with older US3000 banks to eliminate load-shedding disruptions.

Key Features & Benefits

• High Usable 95% Depth of Discharge (DoD): Maximizes daily usable energy extraction while maintaining optimal long-term battery cell health.

• Extended $\ge 6000$ Cycle Life: Premium LiFePO4 cathode material ensures high chemical stability, safe non-explosive operation, and over 6,000 deep cycles backed by up to a 10-year warranty.

• Intelligent Auto-Balancing BMS: Actively protects against abnormal temperature, overcurrent, overvoltage, over-discharge, SoC, and SoH while automatically balancing individual cell voltages.

• Seamless Multi-Inverter Communication: Integrated CAN Bus and RS485 Link Ports (Link Port 0 / Link Port 1) ensure plug-and-play synchronization with leading hybrid inverters.

• Modular Parallel Scalability: Easily expand system capacity over time by daisy-chaining multiple modules in parallel, including existing US3000 battery banks.

• Low Self-Discharge & Zero Noise: Self-cooling convection mode reduces operating noise, holding charge for up to 6 months in standby without memory effect.

• Standard 19-Inch Server Rack Enclosure: Compact matte black metal casing equipped with dual chrome grab handles, front DC quick-connect power terminals (orange positive / black negative), and a 6-segment LED State-of-Charge (SOC) bar.
