5.22kWh Wall Mounted LiFePO4 Residential Solar Battery Pack for Home Energy Storage

1. Product Overview
The Micoe PowerCool-WLL Series is a 51.2V LiFePO4 DC battery pack designed for residential solar storage applications. It supports wall-mounted or floor-standing indoor installation and requires a compatible external hybrid inverter.

Each unit offers a nominal capacity of 5.22kWh / 5.32kWh, delivering up to 4.96kWh of usable energy at a 95% depth of discharge (DOD). The system supports parallel expansion of up to 10 units to accommodate various residential and light commercial project scales. Featuring an advanced BMS with CAN/RS485/WiFi communication, it integrates into Home Energy Management Systems (HEMS) for solar self-consumption, time-of-use management, and backup power. Full international certifications, 5-year warranty, and OEM customization supported by Micoe's source factory.

2. Core Technical Advantages
1. LFP Chemistry & Cycle Life
Utilizing high-safety LiFePO4 cells with excellent thermal stability, effectively mitigating thermal runaway risks. The system is rated for 6000 cycles (@80% DOD), meeting the long-term operational design requirements of residential storage and ensuring stable performance throughout its lifecycle.

2. High DOD & Usable Energy
Supports a 95% depth of discharge (DOD), providing 4.96kWh of usable capacity. This design maximizes the utilization of PV generation and minimizes energy waste, achieving a lower Levelized Cost of Storage (LCOS) over the system's lifecycle.

3. System Expansion & Parallel Capability
The unit supports wall-mounted or floor-standing installation, saving space. The system allows parallel connection of up to 10 units, enabling capacity scaling based on actual project requirements and accommodating future growth in household energy demand.

4. Smart Management & Communication
The built-in intelligent BMS provides protection against over-current, over-voltage, under-voltage, short circuits, and over-temperature. Standard CAN/RS485 interfaces and WiFi modules support low-level protocol matching with mainstream hybrid inverters, along with real-time data monitoring via mobile APP.

5. Environmental Adaptability & Installation
Features a natural cooling design for silent operation. The IP20 protection rating is suitable for dry, protected indoor environments. Operating temperature ranges from 0°C to 55°C for charging and -15°C to 55°C for discharging, adapting to various regional climates.

6. Compliance & Quality Assurance
Certified to multiple international standards, including CE-EMC, UN38.3, IEC62619, IEC60730, IEC62440, and IEC62040, meeting the market access requirements of regions such as Europe and Australia. As a listed manufacturing enterprise, Micoe provides a 5-year factory warranty and supports global OEM/ODM customization services.

3. System Workflow
Daytime Solar Charging: When sunlight is sufficient, rooftop PV panels generate electricity, prioritizing household loads, with surplus energy stored in the PowerCool battery.

Evening Solar Self-Consumption: When solar irradiance decreases and PV generation is insufficient, the battery releases stored solar energy, prioritizing stored power to reduce grid electricity purchases.

Grid Outage Backup: During grid failures, the system rapidly switches with the inverter to continuously power pre-selected critical loads.

System Status Monitoring: LCD screen (optional) + WiFi APP for real-time viewing of battery level, charge/discharge power, and historical operating data.
