Adopting high-quality 3.2V 400Ah LiFePO4 battery cells, configured in a 15S1P series-parallel combination, it not only ensures battery stability but also maximizes cell performance. The 95% Depth of Discharge (DOD) design means the battery can release almost all stored energy, offering higher utilization compared to ordinary batteries and ensuring every kilowatt-hour of electricity is fully utilized. With a cycle life of over 6,000 times, based on typical household usage frequency, it can operate stably for many years without the need for frequent replacement, providing significant advantages in long-term usage costs.

LiFePO4 battery technology itself is renowned for its inherent safety and stability. Unlike other lithium-ion battery chemistries, it is highly resistant to thermal runaway, making it an ideal choice for home energy storage applications where safety is paramount. The 15S1P configuration further enhances the battery pack's reliability by minimizing the impact of individual cell variations, ensuring consistent performance throughout the battery's lifespan.

Flexible Compatibility + Intelligent Protection: Enjoy Peace of Mind in Usage

Strong compatibility is a key highlight of this battery pack. Supporting RS485 and CAN communication protocols, it is widely compatible with most inverters available on the market. Whether you are adding a new energy storage system or upgrading existing equipment, it can seamlessly integrate without additional adaptation costs. Optional Bluetooth and WiFi functionality allow you to real-time monitor key battery data such as voltage, current, remaining capacity, and temperature via your smartphone or computer. This enables remote energy management, bringing intelligence to your home energy system. Additionally, it supports parallel expansion of 1 to 15 units, allowing flexible adjustment of voltage and capacity according to actual needs. From small household electricity supply to large-scale equipment powering, it can handle various requirements with ease.

In terms of safety protection, the battery pack is equipped with an advanced Battery Management System (BMS) that features multiple protection and communication functions. It real-time monitors the battery's operating status and precisely regulates the charge-discharge process. Multiple safety protections against overcharging, over-discharging, over-temperature, over-current, and short circuits fully eliminate potential safety hazards, safeguarding both the equipment and your family. With an IP20/IP21 protection rating, it effectively prevents dust and foreign object intrusion, adapting to various indoor installation environments such as garages, storage rooms, and equipment rooms, ensuring stable operation in different settings.

The intelligent BMS not only enhances safety but also optimizes battery performance. It balances the charge and discharge of individual cells, extending the overall cycle life and maintaining consistent energy output. The remote monitoring function also allows for timely alerts in case of abnormal conditions, enabling proactive maintenance and minimizing downtime.

Versatile Applications: Unlocking New Possibilities for Energy Usage

This energy storage battery pack has a wide range of applications, serving as an all-round assistant for home energy management. When paired with a photovoltaic system, it can efficiently store surplus electricity generated by solar panels during the day, avoiding energy waste. This realizes the model of "self-generation and self-consumption, surplus energy storage", significantly reducing household electricity bills while reducing reliance on the power grid, contributing to environmental protection efforts.

In emergency situations such as sudden power outages, the battery pack can quickly switch to power supply mode, providing continuous electricity for critical electrical equipment such as refrigerators, air conditioners, lighting, and communication devices. This ensures the normal operation of family life, eliminating the inconvenience caused by power outages. For areas with weak power grid coverage such as rural and mountainous regions, it is an ideal independent energy solution. It can build a stable home power supply system without relying on the power grid, improving the quality of life for residents in these areas.

Beyond these core applications, the battery pack also offers additional value in various scenarios. For example, it can be used to shift electricity usage from peak to off-peak hours, taking advantage of lower electricity rates during off-peak periods to further reduce energy costs. It also serves as a reliable backup power source for home offices, ensuring uninterrupted work during power outages. For outdoor enthusiasts or those with mobile energy needs, it can be used as a portable power supply for camping, RV trips, and other outdoor activities, providing convenient and clean energy on the go.
