3 Overview
The 48100E ESS series products use lithium iron phosphate (LFP) as the positive
electrode material. It can be widely used in energy storage systems such as residen-
tial 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 performanc e in high rate, long cycle life, wide
temperature range, and high safety.
3.1.1 Features
3.1 Product Description
•
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℃(recom-
mended 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
