avoided, could result in serious injury or death.

Product Overview 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 battery system 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

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.

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 Installation

Fig 4.6:Multiple JKS-B5150-BI installation process

Step 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 Installation

Fig 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.

2| Close the breaker of the PACK.| Make sure the breaker is ON.
3| Press POWER button for three to eight seconds. Observe the LED indication on panel.| 1.    If both RUN/ALM and SOC lights turn on normally, PACK is powered on successfully.2.     If RUN/ALM light turns red, there is a failure and should solve it before power on again.

Power on the PACK by PCS

1| Connect the battery and PCS.| Make sure the wiring harnesses are well connected.
2| Close the breaker of the PACK.| Make sure the breaker is ON.
3| Power on the PCS. PCS outputs a wake up signal of 5V or an output main circuit voltage signal of 46-58V.| 1.   If both RUN/ALM and SOC lights turn on normal, PACK powers on successfully.2.     If RUN/ALM light turns red, there is a failure and should solve it before power on again.

Power Off

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

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.
