Product Overview

1.1 Intended Use
Each JKS-B5150-BI consists of 50Ah cells which form 51.2V voltage battery module and sixteen serial connection (1P16S).Two to ten JKS-B5150-BI can be connected in parallel and extend the capacity and power of energy storage system. The same type of cell and the same software version of the PACK can be used in parallel. Specifically, the attery syste powers the loads through PCS at nighttime without solar; when solar becomes available during daytime, solar energy powers the loads as a priority and store residual solar power into the JKS-B5150-BI batter system.
1.2 Appearance
JKS-B5150-BI consists of battery module (including cell and mechanical parts), battery management system (BMS) as well as power and communication terminals. Product
appearance is shown as below. 

1.3 Working Principle and Function

JKS-B5150-BI is an energy storage unit composed of electrochemical cells, switch button, battery management unit, power and signal terminals, and mechanical parts. It features better charge and discharge performance, more precise status monitor, longer cycle life, and less self-discharge loss than other batteries. Two to ten PACKs  connected in parallel increase the capacity and power of battery system; the whole battery system communicates to Power Conversion System (PCS) via CAN.

• Monitoring: voltage, current and temperature detection of both single cells and PACK.
• Protection and Alarm: protection and alarm when overvoltage, under voltage, over current, over-temperature or under temperature occurs. See Appendix I for the details.
• Report: report all alarm and status data to PCS.
• Parallel connection: support two to ten PACKs in parallel connection.
• Passive balance function.
• Power off triggered by fault: PACK and PCS communication lost for 25 minutes or under voltage protection for 30 minutes.

Wall  Mounted  InstallationStep 1: Please make sure that the weight capacity of wall should exceed 150kg.
Step 2: Assemble the wall hangers together. If you want to install four packs, make four wall hangers together. We can parallel two to ten at a time .But, it is recommended that no more than four packs be mounted on wall.
Step 3: Place the wall hangers on the wall and mark the holes that need to be punched.
We recommend two persons participate the installation. One person places the wall hangers on wall and ensure the gradienter horizontal; the other person marks the holes.
Each wall hanger has two fixed positions. After mark the holes, put down the wall hangers.
Step 4: Drill a hole at the marked point with a depth of 55mm at the mark with a drill of φ8.Expand the bolt with a hammer into the hole in the wall , install the nut(including
elastic flat pad)and tighten the nut with a wrench.
Step 5: Hang the JKS-B5150-BI on the wall hangers. Adjust the battery level with M6 external hexagon torque wrench and install the safety screws (M4x10 Combination screw) on both sides of all modules.
Step 6: Plug the connected power lines into PACK terminals (red positive terminal and black negative terminal). Plug the well-connected CAN communication line into the
communication ports of PCS and PACK.
Note: The number of wall-mount installations should not exceed four.
Floor Standing InstallationFig 4.7:Multiple JKS-B5150-BI with base installation process
Step 1: Assemble the wall hangers together. If you want to install four packs, make four wall hangers together. We can parallel two to ten at a time . We recommend that the
stack number be no higher than six. However, if necessary our structure allows us to stack higher.
Step 2: Place the mount base where you want the PACK to be mounted. Put the wall hangers on the wall and match the base.
Step 3: Mark the holes that need to be punched. We recommend two persons participate the installation.One person places the wall hangers on wall and ensure the gradienter
horizontal; the other person marks the holes. Noted that only two ends of the top wall hanger and the bottom wall hanger need to be marked.. After mark the holes, put down the wall hangers.
Step 4: Drill a hole at the marked point with a depth of 55mm at the mark with a drill of φ8. Expand the bolt with a hammer into the hole in the wall , install the nut(including
elastic flat pad)and tighten the nut with a wrench.
Step 5: Hang the JKS-B5150-BI on the wall hangers. Adjust the battery level with M6 external hexagon torque wrench and install the safety screws (M4x10 Combination
screw) on both sides of all modules.
Step 6: Plug the connected power lines into PACK terminals (red positive terminal and black negative terminal). Plug the well-connected CAN communication line into the
communication ports of PCS and PACK.
Note:If more than 4 batteries are used, base mounting is recommended.
For floor installation, we recommend that the number of the stacked battery modules is no higher than six.

Power On and Off the Battery

WARNING

• The installation and use of batteries involve much specialized knowledge. Therefore, technicians should be given appropriate technical training and obtain operational certificates in compliance with local laws and regulations. Please ensure technicians have obtained training certificate before operation.
• Please stand on dry insulating objects and do not wear conductive material such as watches and necklace during operation. Insulated tools should be used.
• Do not contact any positions with potential difference.
• Prohibition sign should be hung on the battery:”Non – professionals, do not touch”.
• If any abnormalities occur during the startup phase, power off the  PACK immediately. After problem confirmed, proceed again.
• Make sure the inverter is turned off before checking the PACK.

5.1 Power OnPower ON battery system
Turn the circuit breaker to the “ON” position.Press the power button for 3 seconds to turn on the battery.The battery LED indicator lights up to indicate that the battery has been turned on.

5.2 Power OffPower OFF battery system

Turn the circuit breaker to the “OFF” position.Press the power button to turn off the battery.The battery LED indicator is off,and the battery has been turned off.
Press the power button to turn off the PACK and five LED lights will flicker for three times. If under the situation of multiple packs in parallel, only turning off one of the packs then the whole battery system will turn off.

Maintenance Guide

6.1 Preparation

• Tools like safety gloves, cross head driver and socket wrench should be prepared.
• Turn off and turn on new PACK.

1. If the PACK is power-off. Press power button for 3-8 seconds to turn on.
2. If the PACK is power-on. Press power button once to turn off.

Before maintaining the battery, turn off the breaker and press power button once to make sure the PACK is in the power-off mode. Follow the installation and wire connection procedures specified above. Ensure wires are properly connected before turn the breaker on. After that, turn on the breaker and press power button of any PACK for 3-8 seconds to check if the system normal works.
6.2 PACK Replacement
