Key Features

1. Brand-New Grade A LiFePO4 Cells

This 16kWh Solar home energy storage lithium battery system uses brand-new Grade A lithium iron phosphate cells arranged in a 16S1P architecture, meaning sixteen 320Ah high-capacity cells are directly connected in series to form a single battery module.

Core advantages of this architecture include:

• Simplified and reliable system:

Compared with traditional designs that use multiple small cells connected in parallel and then in series, the parallel cell connections are eliminated. This significantly reduces internal connection points and fundamentally lowers the risk of failures caused by uneven impedance, circulating currents, and related issues, greatly improving overall safety and reliability.

• Balanced performance and longer lifespan:

All cells operate in a pure series configuration with a consistent current path, eliminating imbalance issues within parallel groups. The Battery Management System (BMS) independently and accurately monitors and balances the voltage of each 320Ah cell, ensuring synchronous aging and maximizing the overall cycle life of the battery system.

• High energy density and easy maintenance:

The use of single high-capacity cells results in a more compact structure and higher energy density for the same total energy. Fewer cells and connectors also simplify maintenance and diagnostics over the system’s lifetime.

By combining the inherent safety and long lifespan of LiFePO4 chemistry with a simple and efficient circuit structure, this 16KWh 48V 320Ah home energy storage lithium battery delivers a stable and durable solution from cell level to system level.

Under normal operating conditions, it supports up to 9,500 deep cycles and is designed for more than 10 years of stable operation.

2. Intelligent Battery Management System (BMS) with 2A Active Balancing

This system is equipped with an intelligent BMS featuring 2A active balancing, providing comprehensive battery protection and lifespan optimization.

• Intelligent monitoring:

Real-time monitoring of each cell’s voltage, current, and temperature with an accuracy of ±0.5%.

• 2A active balancing:

Balancing current up to 2A, significantly reducing cell discrepancies. Automatic balancing throughout the entire charge and discharge process with efficiency greater than 85%, improving overall pack consistency.

• Four-level safety protection:

Comprehensive protection against overcharge, over-discharge, short circuit, and high/low temperature conditions.

3. LCD Touchscreen Display

The high-resolution LCD touchscreen displays key operating parameters in real time, including SOC, voltage, current, individual cell and ambient temperature, and cycle count, allowing you to monitor and maintain the system locally with ease.

The touchscreen integrates fully with the BMS and supports multiple mainstream communication protocols (CAN / RS485). You can select and switch protocols via the on-screen menu, ensuring stable communication and compatibility with major inverter brands such as Victron, Growatt, Sofar, Solis, and GoodWe.

4. Industrial-Grade Caster Design

High load-bearing industrial-grade casters let you move the system easily without forklifts or additional equipment, significantly reducing installation and maintenance effort.

This design suits applications that require frequent repositioning, temporary on-site deployment, or future capacity expansion.

The locking function keeps the system stable and safe during fixed installation, balancing flexibility with security.

5. Parallel Expansion Support

As your electricity demand increases, you can connect multiple battery units in parallel without replacing the entire system, flexibly expanding total capacity to hundreds of kilowatt-hours.

This feature makes the system ideal for residential and commercial energy storage projects that start small and grow gradually, helping you reduce upfront investment and avoid repeated installations.

6. IP65 Protection Rating + Self-Heating Function

The fully sealed enclosure effectively resists dust, rain, and humid environments, supporting both indoor and semi-outdoor installations.

A built-in self-heating system automatically activates in low-temperature conditions, ensuring safe charging and stable operation at temperatures as low as -20°C, reducing winter downtime and performance degradation.

7. Plug & Play Design

Standard RS485 and CAN communication interfaces enable direct connection to mainstream inverters without complex wiring or secondary development.

This significantly shortens installation and commissioning time, allowing faster system deployment while simplifying long-term monitoring and maintenance.

8. Quality Commitment

Each 16kWh 48V 320Ah LiFePO4 Solar home energy storage battery system is assembled using brand-new Grade A lithium iron phosphate cells, ensuring consistency and long service life from the source.

Before leaving the factory, every battery undergoes capacity testing, charge/discharge performance testing, vibration testing, and multiple safety tests to verify stability and reliability during long-term operation and transportation.

Based on the use of high-quality Grade A LiFePO4 cells and a rigorous, systematic factory testing process, we are able to offer a 10-year warranty on this 16kWh 48V 320Ah Solar home energy storage battery system
