SMTE 15kWh 52V 300Ah LiFePO4 Lithium Battery – High-Capacity Solar Energy Storage (15/12 Low Voltage, IP55)

Power your large residential home, estate, or commercial business with the 15kWh (15/12) 52V 300Ah LiFePO4 Lithium Battery. Engineered with premium Lithium Iron Phosphate chemistry and an advanced Shunt Trip-protected Battery Management System (BMS), this high-capacity low-voltage storage unit delivers 12kWh of daily usable energy at 80% DoD. Designed to suit 48V inverter setups with up to 15kVA rated continuous inverter power, it features a massive 300A continuous current capability, pre-wired dual $2\times 50\text{ mm}^2$ DC fly leads per electrode, dual RJ45 CAN Bus ports, and an IP55-rated aluminum enclosure built for an expected service life of over 16 to 20 years.

Key Features & Benefits

• Massive 15kWh Total Capacity (12kWh Usable): Delivers 12kWh of dependable daily energy at 80% DoD to reliably support heavy household loads, central air conditioning, and light commercial operations.

• Heavy-Duty 300A Continuous Current: Delivers up to 300A continuous charging and discharging current to easily handle large power surges and high inverter demands up to 15kVA.

• Exceptional >16-Year Service Life: Premium LiFePO4 chemistry provides $>5500$ cycles at 80% DoD (>16 years expected life) and $>7500$ cycles at 50% DoD (>20 years expected life).

• BMS-Actuated Shunt Trip Circuit Breaker: High-current breaker automatically trips via the BMS during critical faults and features manual reset for ultimate electrical safety.

• Heavy-Duty Integrated DC Fly Leads: Equipped with dual $2\times 50\text{ mm}^2$ pre-wired positive (red) and negative (black) cables per electrode for fast, low-resistance inverter connectivity.

• Smart CAN Bus Control Interface: Dual RJ45 CAN Bus communication ports provide seamless synchronization with leading 48V hybrid inverters and multi-battery parallel expansion.

• Rugged IP55 Powder-Coated Enclosure: Built with high-grade aluminum with a durable white powder-coated finish and silver back, suitable for protected indoor and undercover environments.

• Comprehensive Human Interface: Features a 0–100% State of Charge (SOC) meter, error alert light, error reset button, and a serial RS232 programming port.
