3 Overview
3.1 Product Description
The VT48100E ESS series products use lithium iron phosphate (LFP) as the
positive electrode material. It can be widely used in energy storage systems such
as residential energy storage, back-up power, and PV self-consumption
optimization.
The battery pack is composed of 15 cells/16 cells of LFP batteries in series
connection, with low self-discharge, high energy density, and no memory effect. This
type of battery also has excellent performance in high rate, long cycle life, wide
temperature range, and high safety.
3.1.1 Features
• High energy density
Higher volume ratio energy and weight ratio energy.
• Maintenance-free
The battery pack is maintenance-free in the process of using, which can save
customers' battery operation, maintenance testing costs and reduce the frequency of
on-site replacement.
• Long cycle life
The battery pack life is 3 times long than the ordinary lead-acid batteries.
• Excellent temperature characteristics
When charging, the battery working temperature can reach 0℃～＋60℃
(recommended using temperature: +15～＋35℃). When discharging, the battery
working temperature can reach -20℃～＋60℃ (recommended using temperature:
+15～＋35℃).
3.1.2 Basic Functions
• Monitor
The battery system uses a high-performance BMS, it has protection functions
such as current, voltage.
• Alarm
Support abnormal alarms such as overvoltage, under-voltage, overcurrent,
short circuit, high and low temperature, battery failure, hardware failure, etc.
• Communication
Provide dual RJ45 interfaces, upload alarming and status data through the
RS485/ CAN communication protocol.
