15kWh Home Energy Storage System Scalable Design Compact Structure

Product Overview

The 15kWh Energy Storage System is a compact and scalable lithium battery energy storage solution designed for residential, light commercial, solar, and backup power applications. Built with Lithium Iron Phosphate (LFP) battery technology, the system combines battery modules, an intelligent Battery Management System (BMS), thermal management, and energy management functions into a flexible energy storage platform.

With a 15kWh rated energy capacity, the system can store excess solar energy or electricity during off-peak periods and supply power when energy demand increases or the grid is unavailable. Its compact design makes it suitable for homes, villas, small businesses, and other distributed energy applications.

Key Features

• 15kWh Energy Capacity – Provides practical energy storage for residential and light commercial applications.
• LFP Battery Technology – Uses lithium iron phosphate battery chemistry for stationary energy storage.
• Intelligent BMS – Monitors battery voltage, current, temperature, SOC, and other key operating parameters.
• Flexible Installation – Can be configured for floor-mounted, wall-mounted, or other installation arrangements according to the system design.
• Solar Energy Integration – Can be paired with compatible hybrid inverters to store excess solar generation for later use.
• Scalable Design – Multiple battery units can be connected in parallel to increase total storage capacity.
• Compact Structure – Designed to provide high storage capacity while minimizing installation space.
• Multiple Communication Options – Can support interfaces such as CAN and RS485 for inverter and energy management integration.

Applications

The 15kWh Energy Storage System is suitable for:

• Residential solar energy storage
• Whole-home backup power
• Home energy management
• Solar self-consumption
• Time-of-use energy management
• Peak load management
• Light commercial energy storage
• Small business backup power
• Off-grid and hybrid solar systems
• Distributed energy storage
• Small microgrid applications

Intelligent Energy Management

The system can work with compatible hybrid inverters and energy management systems to coordinate battery charging and discharging.

Depending on the configuration, the system can support:

• Solar energy storage
• Automatic charge and discharge control
• Real-time battery monitoring
• State of charge (SOC) monitoring
• Backup power management
• Time-of-use energy optimization
• Remote monitoring
• Multiple-unit parallel operation

Safety & Battery Management

The 15kWh system incorporates multiple battery protection functions through its intelligent BMS. The BMS can monitor cell voltage, current, temperature, SOC, and other operating conditions to help protect the battery during charging and discharging.

LFP chemistry is widely used in stationary energy storage because of its thermal stability and suitability for repeated charge and discharge operation. Current 15kWh products on the market commonly use LFP cells and integrated BMS protection.

Additional protection functions, such as overcurrent, overvoltage, overtemperature, short-circuit, and emergency shutdown protection, can be configured according to the final system design.
