SMTE 70kWh 518.4V High Voltage LiFePO4 Battery – Commercial ESS

SMTE 70kWh 518.4V High Voltage LiFePO4 Lithium Battery Complete Set – Commercial Energy Storage System (Stackable Tower with High-Voltage Master BMS Box)

Power large commercial facilities, industrial plants, agricultural operations, or luxury off-grid estates with the 70kWh 518.4V High Voltage LiFePO4 Lithium Battery Complete Set. Engineered as a high-density, multi-module stackable tower paired with a master high-voltage BMS control box, this system operates at an efficient 518.4V nominal voltage to minimize transmission current losses and maximize round-trip efficiency. Built with premium Lithium Iron Phosphate (LiFePO4) chemistry, an integrated high-voltage DC circuit breaker, smart color digital display, and robust caster wheel mobility, it delivers high-performance energy security and seamless high-voltage hybrid inverter integration.

Key Features & Benefits

• Massive 70kWh High-Voltage Storage: High-capacity commercial storage stack designed to power three-phase hybrid systems, heavy machinery, and critical industrial loads.

• 518.4V High-Voltage Architecture: Drastically reduces continuous current flow and heat dissipation compared to low-voltage battery setups, maximizing inverter efficiency and solar round-trip conversion.

• Master High-Voltage BMS Control Box: Top-mounted control module features integrated DC safety disconnect switches, circuit breakers, and advanced multi-cell monitoring.

• Smart Multi-Parameter Color Display: Real-time visual monitoring of total battery bank voltage, individual cell balance, state of charge (SOC), and temperature metrics.

• Modular Plug-and-Play Stacking: Stackable vertical tower configuration allows neat, space-saving installation without complex external inter-rack conduit routing.

• Heavy-Duty Mobile Chassis: Equipped with heavy-duty locking caster wheels and adjustable leveling feet for easy indoor transport, precise positioning, and rock-solid stability.

• Multi-Protocol Inverter Communication: Dual communication ports (CAN / RS485) guarantee seamless synchronization with leading three-phase high-voltage hybrid inverters (Deye, Sunsynk, Solis, and more).
