3.1 Product Description
The VT-48280 product 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 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℃~+55℃.
(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 2*RJ45 interfaces, upload alarming and data of batteries through the
RS485/CAN communication protocol.
3 Overview
5
•Parallel connection application
Max. support 15pcs batteries in parallel connection. (Recommendation: for bettter
performance, when the number of batteries exceeds 2pcs, please connect all batteries
to the bus-bar.)
•Balance function
Support the cells balance function.
3.2 Application Scenario
The battery pack is used to provide backup power, load shifting, peaking
shaving and can be used for residential energy storage, solar energy storage and
other application scenarios.
The normal working operation diagram of the battery pack can be as shown in
the figure below.
Fig. 3-1 Working Diagram of the Battery Pack
4 Application Description
6
4.1 Parallel Connection Application
The battery packs support parallel connection, and synchronously increases the
backup time or backup power.
Confirm the consistency between the battery packs, check the SOC and voltage
and turn off the batteries before connecting them in parallel.
4.2 Low-temperature Application
•Low-temperature Charging
The battery pack does not support direct charging of the battery below 0°C.
When the minimum temperature of the battery is below 0°C, the BMS will cut-off the
charging circuit and cannot be charged.
•Low-temperature Discharging
The battery pack does not support discharge below -20°C. When the minimum
temperature of battery is below -20°C, the BMS will cut-off the discharge circuit and
cannot discharge.
4.3 Low Battery-capacity Storage (SOC≤5%)
After the battery pack is power off, there will be BMS static power consumption
and self-discharge loss. In actual scenarios, it is necessary to avoid low-battery-pow-
er state（SOC≤5%）storage. If it is unavoidable, the longest storage period is 30days
@25°C, 15 days@45°C. The battery needs to be recharged in time after storage,
otherwise the battery may be damaged due to over-discharge, and the entire battery
pack needs to be replaced.
5 Product Introduction
7
The following conditions may cause the battery pack to be stored in a
discharged state:
After the utility power failure, the line/fault cannot be eliminated in time, and
the power supply cannot be restored for a long time.
After the installation and commissioning work is completed, the utility power
is turned off directly, but the battery pack is not powered off, which will cause the
battery to enter the low power consumption mode.
Other reasons cause the battery pack to fail to enter low power consumption
normally.

If you will install more than 2pcs batteries (No more than 15pcs) , you will have
the following two system wiring options.
Option 1. Connect all batteries to the bus bar.
NOTE
For this wiring solution, you will need to prepare bus bars and power cables to
connect the bus bars to the inverter in addition. You can either purchase them
independently or obtain them from Vtac or the supplier.
In this wiring solution, the Max. output current of the system will be 150A* the

9.3 Battery Storage
The recommended storage temperature is 15℃~35℃.
Battery performance degradation after long-term storage, please shorten
shelf time as possible as you can.
Recharge charge before using to recover capacity loss of self-discharge during
storage and transport.
Storage battery should be at 40%-50% SOC when the battery is not used for a
long time.
Storage battery over 40°C or under 0°C will reduce battery life.
Storage battery in dry and low temperature, well ventilated place.
If the battery is not used for a long time, the battery must be charged at regular
intervals. The charging requirements are as follows：
