YIMAI Outdoor Integrated Energy Storage Cabinet | Waterproof IP55 LiFePO4 Battery Energy Storage System for Telecom & Industrial Use

Product Overview

Core Technical Advantages

1. IP55 Outdoor Waterproof & Dustproof Design
   • The cabinet features a robust metal enclosure with IP55 protection rating, effectively preventing rain, dust, and moisture ingress, making it suitable for outdoor installation in all weather conditions.
   • The sloped roof design drains rainwater away, while the sealed door with a lock ensures physical security and prevents unauthorized access.
   • Built-in ventilation and heat dissipation system maintains optimal operating temperature, even in extreme hot or cold environments (-20°C~60°C).
2. Long-Life LiFePO4 Battery Technology
   • Uses automotive-grade LiFePO4 cells with a cycle life of 2000~3000 cycles (8~10 years of daily use), far exceeding lead-acid batteries (300~500 cycles).
   • High thermal stability and chemical safety, eliminating fire and explosion risks associated with other lithium chemistries.
   • Modular battery design allows for easy capacity expansion and replacement, reducing maintenance costs and extending system lifespan.
3. Intelligent Battery Management System (BMS)
   • The built-in BMS monitors each battery cell in real time, providing protection against over-charge, over-discharge, over-current, short-circuit, and over-temperature.
   • Cell balancing function ensures uniform charging and discharging of battery cells, maximizing battery capacity and lifespan.
   • Supports remote monitoring and data logging via RS485/Modbus or 4G/5G communication, allowing users to check system status and receive alarm notifications from anywhere.
4. Integrated Power Conversion & Charging
   • Equipped with a bidirectional inverter that delivers stable 220V/110V AC pure sine wave power, compatible with sensitive electronics and industrial equipment.
   • Built-in MPPT solar charge controller supports solar panel input, enabling off-grid renewable energy harvesting.
   • Supports grid charging and generator charging, ensuring flexible power supply options for different application scenarios.
   • Auto-switching between power sources ensures uninterrupted power supply to critical loads.
5. Smart Thermal Management & Environmental Control
   • The cabinet includes a temperature-controlled ventilation system and optional heater/air conditioner, maintaining the internal temperature within the optimal range for battery and inverter operation.
   • Prevents overheating in summer and freezing in winter, ensuring reliable performance in extreme climates.
6. Comprehensive Safety & Security Features
   • Overload, short-circuit, and over-temperature protection for both inverter and battery.
   • Flame-retardant materials and internal fire suppression system (optional) prevent fire hazards.
   • Door status monitoring and alarm function alerts users to unauthorized access attempts.
   • Surge and lightning protection safeguards the system against electrical storms.
