- Information
Product Overview
The YIMAI Mobile Energy Storage System is a versatile, self-contained power unit built around long-cycle-life LiFePO4 battery cells. Combining energy storage, inversion, and distribution into a single wheeled cabinet, it provides clean, stable power for both AC and DC loads without relying on the grid. Available in capacities from 5kWh to 20kWh, this system supports solar charging, generator input, and grid charging, offering a flexible, eco-friendly alternative to diesel generators and traditional backup power solutions.
Core Technical Advantages
-
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.
- Built-in intelligent BMS (Battery Management System) provides real-time monitoring and protection against over-charge, over-discharge, over-current, short-circuit, and over-temperature, extending battery lifespan.
-
Pure Sine Wave Inverter Output
- Delivers stable 220V/110V AC pure sine wave power, compatible with sensitive electronics (computers, medical devices, appliances) and heavy-duty tools (power tools, pumps, compressors).
- Inverter efficiency up to 95%, minimizing energy loss and maximizing usable power.
- Supports multiple output interfaces: AC outlets, DC terminals, and USB ports, enabling simultaneous charging of multiple devices.
-
Flexible Charging Options
- Grid Charging: Fast recharges from the utility grid in 4~8 hours.
- Solar Charging: Compatible with solar panels (MPPT controller included) for off-grid renewable energy harvesting.
- Generator Charging: Can be charged by a portable generator for extended off-grid operation.
- Auto-switching between charging sources ensures uninterrupted power supply.
-
Mobile & Modular Design
- Mounted on heavy-duty casters for easy mobility between job sites, event venues, or home locations.
- Modular battery design allows for capacity expansion by adding extra battery modules, scaling from 5kWh to 20kWh or higher.
- Compact cabinet layout integrates all components (batteries, inverter, charger, distribution) into a single unit, saving space and simplifying installation.
-
Intelligent Monitoring & Control
- Front-panel LCD display shows real-time battery state of charge (SoC), input/output power, voltage, and fault alerts.
- Remote monitoring via RS485/Modbus or WiFi (optional) allows users to check system status and adjust settings from a smartphone or PC.
- Programmable charging/discharging schedules optimize energy usage and reduce grid dependency.
-
Comprehensive Safety & Protection
- Overload, short-circuit, and over-temperature protection for both inverter and battery.
- Flame-retardant cabinet and internal fusing prevent fire hazards.
- Isolated design ensures user safety during operation and maintenance.
