SMTE 40kWh 52V 800Ah LiFePO4 Lithium Battery – High-Capacity Solar Energy Storage (40/32 Low Voltage, 38kW Peak Discharge)

Power commercial operations, large industrial sites, multi-dwelling residential complexes, or off-grid agricultural facilities with the 40kWh (40/32) 52V 800Ah LiFePO4 Lithium Battery. Engineered with high-grade Lithium Iron Phosphate chemistry and an advanced Shunt Trip-protected Battery Management System (BMS), this floor-standing storage tower delivers 32kWh to 36kWh of daily usable energy. Designed to suit 48V low-voltage hybrid inverter systems up to 25kVA continuous capacity, it features a massive 750A peak discharge capability (38kW), pre-wired dual $2\times 95\text{ mm}^2$ Permopower DC fly leads per electrode, dual RJ45 CAN Bus ports, and an expected service life of over 16 to 20 years for ultimate load-shedding protection.

Key Features & Benefits

• Massive 40kWh Total Storage (32–36kWh Usable): Delivers 32kWh at 80% DoD and up to 36kWh at 90% DoD to comfortably run high-draw commercial machinery, multi-unit residential loads, and central HVAC systems.

• Massive 38kW / 750A Peak Discharge: Delivers 600A continuous discharge (30kW) and up to 750A peak surge (38kW) to effortlessly handle heavy inductive starts and commercial motor spikes.

• Exceptional >16-Year Service Life: Premium LiFePO4 cell chemistry guarantees over 5,500 cycles at 80% DoD (>16 years expected life) and over 7,500 cycles at 50% DoD (>20 years expected life), backed by a 10-year warranty.

• BMS-Actuated Shunt Trip Circuit Breaker: High-current safety breaker automatically trips via BMS fault detection and features manual reset functionality for total protection.

• Heavy-Duty Dual $2\times 95\text{ mm}^2$ Permopower Fly Leads: Comes pre-fitted with positive and negative heavy-gauge DC fly leads per electrode for low-resistance, high-current inverter coupling.

• Smart CAN Bus & USB Diagnostics: Features dual RJ45 CAN Bus ports for seamless communication and parallel synchronization with leading 48V hybrid inverters, plus a USB serial interface for PC troubleshooting.

• Integrated Human Interface: Equipped with a 0–100% State of Charge (SOC) meter, error status LED indicator, and error reset button.

• Durable White Aluminum Chassis: Upright floor-standing tower built with high-grade white painted aluminum, solid base support feet, and recessed side grab handles for clean indoor placement.
