2 Safety
2.1 Safety Precautions
Before carrying out battery work, you must read carefully the safety precautions and master the correct installation and connection methods of the battery.
Prohibit to turn it upside down, tilt, or collide. Prohibit to short-circuit the positive and negative poles of the battery, otherwise it will cause the battery to be damaged. Prohibit to throw the battery pack into a fire source. Prohibit to modify the battery, and it is strictly prohibited to immerse the battery in water or other liquids. DO NOT place installation tools on the battery during battery installation. DO NOT disassemble, squeeze, bend, deform, puncture, or shred the battery without the authorization of authorized dealers. DO NOT exceed the temperature range, otherwise it will affect the battery performance and safety. The battery circuit must be kept disconnecting status during installation and maintenance operations. Check the battery connection end bolts regularly to confirm that the bolts are tight.

2.2 Abuse Operation
The battery pack needs to avoid abuse operations under the following (including but not limited to) conditions:

Abuse Operation Reverse connection of positive
and negative poles External short circuit
Series connection application

Protection Description
If the positive and negative poles are connected reversely, the battery will be directly damaged.
If the battery pack is short circuited externally, the battery will be directly damaged.
The battery pack does not support the application of battery packs in series. If the battery packs are forced to be connected in series, the batteries may be directly damaged,
and may even cause fire, explosion and other dangers.

3 Overview
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

3 Overview
· 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
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 (SOC5%)
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-power stateSOC5%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

5 Product Introduction
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.

8 Make Your System Run Check before Running
Step 1. Check whether the cables are connected correctly. Step 2. Check whether the batteries are grounded. Step 3. Check these following status of switchs.
The power switch of the battery should be off. The DC switch of the inverter should be off. The circuit breaker from the inverter to the grid should be off.
Power-on Step 4. Turn on the DC switch of inverter. Turn on the switch between the inverter and grid. Turn on the circuit breaker between the inverter and battery (if any). Step 5. Turn on the power switch of battery. And waiting for the Run/Alarm
indicator lights from green blinking into green, means power on successfully
NOTE
· If you want to Power off your system
If you need to shut down the system for some reason, please refer to the following steps.
Step 1. Turn off the inverter first. Step 2. Turn off the battery then.
