7.2 Product Description

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.

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

Wall Mounted Installation
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.
Adjust the screw to ensure the
battery in horizontal position

Floor Standing Installation
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.

Method for calculating rated capacity:
Rated capacity of the measured module: 45 Ah
Number of modules connected in parallel: 10
Calculated rated capacity (Ah) = 45 Ah×N = 45*N Ah (N=1~10)
Recommend charging method declared by the manufacturer:
1.Constant current 25A charging to 54V;
2.Constant current 10A charging to 55V;
3.Constant current 2A charging to 55V;
