Built with advanced lithium iron phosphate technology, this battery delivers deep cycle performance, excellent safety, and robust durability.

The LVTOPSUN 51.2V 314Ah LiFePO₄ Lithium Battery is a high-performance 16kWh energy storage solution designed for residential, commercial, and industrial solar power systems. Built with advanced Lithium Iron Phosphate (LiFePO₄) technology, this battery offers superior safety, long lifespan, and reliable deep-cycle performance.

With a lvtopsun 51.2v 314ah lithium-ion-battery of 51.2V, it is fully compatible with most lvtopsun 51.2v 314ah lithium-ion-battery solar inverters, making it ideal for off-grid, hybrid, and backup power applications. The integrated smart BMS (Battery Management System) ensures protection against over-charge, over-discharge, short circuit, and overheating, guaranteeing stable and safe operation.

This battery supports high charge and discharge currents, enabling it to power heavy loads efficiently. Its long cycle life of over 8000 cycles at 90% DOD significantly reduces replacement costs, offering excellent long-term value. Designed with RS485, RS232, and CAN communication ports, it seamlessly integrates with popular inverter brands.

The lvtopsun 51.2v 314ah lithium-ion-battery features a robust, floor-standing design with IP65 protection, making it suitable for demanding environments. Multiple units can be connected in parallel to expand storage capacity for larger energy systems

 Installation Instructions

1. Place the battery on a flat, stable surface (floor-standing position).

2. Ensure adequate space around the battery for ventilation.

3. Connect the positive (+) and negative (–) terminals to the inverter using proper-rated DC cables.

4. Tighten all terminals securely to avoid loose connections.

5. If using communication cables (CAN/RS485), connect them between the battery and inverter.

6. For parallel systems, ensure all batteries have:

   • Same voltage and capacity

   • Same cable length

   • Same SOC before connection

 Inverter Configuration (Recommended)

• Battery Type: Lithium / LiFePO₄

• Bulk / Absorption Voltage: 56.0 – 58.4 V

• Float Voltage: 54.0 – 54.5 V

• Low Voltage Cut-off: ≥ 44.8 V

• Max Charge Current: ≤ 150 A

• Max Discharge Current: ≤ 200 A

If the inverter supports CAN/RS485, set it to BMS communication mode.

Power ON / OFF Instructions

Power ON

1. Ensure all wiring is correctly connected.

2. Turn ON the battery power switch.

3. Wait for the SOC display to light up.

4. Turn ON the inverter.

Power OFF

1. Turn OFF the inverter first.

2. Turn OFF the battery power switch.
