ECOLFP2407 25.6V 7.5Ah LiFePO4 Solar Tracker Battery
Integrated MPPT solar charge controller with wide temperature operation range (-20℃ to 60℃)
Product Overview
The ECOLFP2407 is a purpose-built 25.6V lithium iron phosphate (LiFePO4) battery pack engineered specifically for solar tracking systems. Combining 192Wh of reliable energy with an integrated MPPT charge controller, it optimizes solar energy harvest directly from photovoltaic panels—ensuring trackers maintain precise sun alignment throughout the day. Designed for outdoor durability, wide-temperature operation, and seamless plug-and-play installation, this battery delivers consistent, maintenance-free power for residential, commercial, and agricultural solar tracking applications.
Key Features
Integrated MPPT Controller: Built-in Maximum Power Point Tracking with DC 16V-36V input range and 7.5A maximum input current for optimal solar energy harvest
Wide Temperature Operation: Discharges from -20℃ to 60℃ with optional low-temperature heating for cold-weather charging capability
Long Cycle Life: Over 2000 charge-discharge cycles at 100% depth of discharge with greater than 80% capacity retention
Comprehensive Protection: Integrated Battery Management System safeguards against overcharge, over-discharge, overcurrent, short circuits, and extreme temperatures
Compact & Lightweight: Weighing only 2.4kg in a compact PVC enclosure for easy integration onto tracker frames
Smart Monitoring: Optional UART communication for real-time monitoring of voltage, current, and temperature
