48V 20Ah LTO Solar Tracker Battery 960Wh High Voltage Pack for Utility Scale Trackers

48V 20Ah LTO Solar Tracker Battery – 960Wh High Voltage Pack for Utility Scale Trackers

The ECOLTO4820 is a 48V 20Ah lithium titanate battery designed for the drive and control electronics of utility scale single axis solar trackers. With 960Wh of usable energy and a 100A continuous discharge rating, it supplies enough burst power to move long rows of modules through the full 120 degree tracking arc and still hold reserve capacity for night time controller standby and communication.

Key Features

• Lithium titanate chemistry rated for more than 20000 charge and discharge cycles at 1C with 80% depth of discharge
• Stable output from -40C to 60C, so tracker movement and stowing remain reliable in desert heat and winter cold
• 100A continuous and 600A pulse discharge supports multi motor tracker rows from a single pack
• Integrated 20S smart BMS with over charge, over discharge, over current, short circuit and thermal protection
• Optional CAN 2.0B and RS485 communication for SCADA level monitoring of state of charge and cell status
• Sealed IP54 ABS housing with M8 terminals for direct mounting inside the tracker control cabinet
