Safety Gear
It is recommended to wear the following safety gear when dealing with the battery pack

Installation

Package Items
Unpacking and check the Packing List

1. For battery module package:
   Two power cables and one communication cable for each battery package: Grounding cable: Grounding cables use 10AWG yellow-green cables.
   US3000 modules’ grounding is based on metal directly touch between the module’s surface and rack’s surface. So it needn’t grounding cables at all. If uses normal rack, it can remove the paint at the corresponding place. Or install a grounding cable to the grounding point of the modules.

2. For Battery system connects to inverter:
   Two long power cables (current capacity 120A) and one communication cable for each energy storage system:

NOTE
These three long cables are belonging to External Cable Kit, NOT in battery package. They are in another extra small cable box. If there is anything missed please contact dealer.

Multiple Battery Groups CAN/RS485 Communication Cable Connection

Trouble Shooting Steps

Problem determination based on:

1. Whether the battery can be turned on or not;
   If battery is turned on, check the red light is off, flashing or lighting;

2. If the red light is off, check whether the battery can be charged/discharged or not.

Preliminary determination steps:

1. Battery cannot turn on, switch on the lights are all no lighting or flashing.
   If the battery external switch is ON, the RUN light is flashing, and the external power supply voltage is 48V or more, the battery still unable to turn on, please contact distributor.
   The battery can be turned on, but red light is lighting, and cannot charge or discharge.
   If the red light is lighting, that means system is abnormal, please check values as following:

   • Temperature: Above 50 or under -10 , the battery could not work.
     Solution: to move battery to the normal operating temperature range between -10 and 5

   • Current: If current is greater than 100A, battery protection will turn on.
     Solution: Check whether current is too large or not, if it is, to change the settings on power supply side.

   • High Voltage: If charging voltage above 54V, battery protection will turn on.
     Solution: Check whether voltage is too high or not, if it is, to change the settings on power supply side.

   • Low Voltage: When the battery discharges to 44.5V or less, battery protection will turn on. Solution: Charge the battery for some time, the red light turn off

Excluding the four points above, if the faulty is still cannot be located, turn off battery and repair.

The battery cannot be charged or discharged

1. Cannot be charged:
   Disconnect the power cables, measure voltage on power side, if the voltage is 53~54V, restart the battery, connect the power cable and try again, if still not work, turn off battery and contact distributor .

2. Unable to discharge:
   Disconnect the power cables and measure voltage on battery side, if it is under 44.5V, please charge the battery; if voltage is above 48V and still cannot discharge, turn off battery and contact distributor.

Emergency Situations

1. Leaking Batteries
   If the battery pack leaks electrolyte, avoid contact with the leaking liquid or gas. If one is exposed to the leaked substance, immediately perform the actions described below. Inhalation: Evacuate the contaminated area, and seek medical attention.
   Contact with eyes: Rinse eyes with flowing water for 15 minutes, and seek medical attention. Contact with skin: Wash the affected area thoroughly with soap and water, and seek medical attention.
   Ingestion: Induce vomiting, and seek medical attention.

2. Fire
   NO WATER! Only dry powder fire extinguisher can be used; if possible, move the battery pack to a safe area before it catches fire.

3. Wet Batteries
   If the battery pack is wet or submerged in water, do not let people access it, and then contact Pylontech or an authorized dealer for technical support.

4. Damaged Batteries
   Damaged batteries are dangerous and must be handled with the utmost care. They are not fit for use and may pose a danger to people or property. If the battery pack seems to be damaged, pack it in its original container, and then return it to Pylontech or an authorized dealer.

NOTE
Damaged batteries may leak electrolyte or produce flammable gas.
In case a damaged battery needs recycling, it shall follow the local recycling regulation (ie. Regulation (EC) Nº 1013/2006 among European Union) to process, and using the best available techniques to achieve a relevant recycling efficiency.

Any further questions, please contact Pylontech: service@pylontech.com.cn

Remarks

Recycle and disposal.
In case a battery (normal condition or damaged) needs disposal or needs recycling, it shall follow the local recycling regulation (i.e. Regulation (EC) Nº1013/2006 among European Union) to process, and using the best available techniques to achieve a relevant recycling efficiency.

Storage , Maintenance and Expansion

1. It is required to charge the battery at least once every 6 months, for this charge maintenance make sure the SOC is charged to higher than 90%
2. Every year after installation. The connection of power connector, grounding point, power cable and screw are suggested to be checked. Make sure there is no loose, no broken, no corrosion at connection point. Check the installation environment such as dust, water, insect etc. make sure it is suitable for IP20 battery system.
3. A new battery module can be added onto an existing system at any time.

Please make sure the new battery is acting as the master. The new module, due to a higher SOH may have a difference on SOC with existing system, but it will not affect the parallel connection system performance.
