System Information

Product Introduction

SG/EBS-5150 is a high-voltage battery storage system based on lithium-iron phosphate technology. It is used to primarily store excess PV power that is generated by an inverter based on PV system.

Connection Area

Start

ON

For multiple Battery Modules in series, long press (for more than 5 seconds) Start button of the High-voltage box (which is connected to the inverter), the Normal LED indicator on the front panel will flash. L1 to L5 show the battery SOC,L6 shows the battery status. The high-voltage box which contains the BMS will automatically encode and assign an ID to each battery module and the battery will operate normally.

OFF

Press Start button of the High-voltage box (which is connected to the inverter) for more than 5s, the LED indicator on the front panel will flash, and then release the button, the master pack will shut down after all the slave packs shut down (Sleep Mode).
Tip: lf the system does not work, keep the internal DC switch on the battery cluster closed.

Link Communication Port

The Link Communication Port is the interface between the battery packs and the inverter.The inverter retrieves the battery data such as SOC,DOD, charge current via this connection.
RJ45 port supports CAN / RS485 / RS232 communication protocol.
CAN/RS485 communication terminal (RJ45 port) connects to the inverter and follows CAN / RS485 protocol.
RS232 communication terminal (RJ45 port) follows RS232 protocol, for manufacturer or professional engineer to debug or service.

Link Power/Link in/Link out

Link Power/Link in/Link out are used for the communication between the battery packs.
The battery pack close to the inverter is the master pack, others are the slave pack.

LED Indicator Definition

flash 1 – every 0.25s on/3.75s off
flash 2- every 0.5s on/ 0.5s off
flash 3 – every 0.5s on / 1.5s off

Installation

Step 1

Place the base against the wall, the distance between the base and the wall is 30mm as followed.
- Note: Levelness of the base is less than 2mm.

Step 2

Screw the locating pin into the base and put the first battery pack on the base.

Step 3

Secure the battery module to the base with the stainless steel plate.

Step 4

Place the next battery module on top of the first battery module and secure the battery modules with the fixing plate. Repeat this step until all battery modules have been installed. Place the high-voltage box on top of the last module and secure it using the L-shape wall hanging bracket.

Step 5

Attached the L-shape wall hanging bracket onto the high voltage box as shown in the image.

Step 6

Drill three holes of in the wall and insert three screw plugs.Insert three screws to secure the L-shape wall hanging bracket to the wall.

Step 7

Secure the top of the high voltage box with the provided screws.

Step 8

Connect the small fixing plate between each modules as follows.

Step 9

Connect the power cables between the battery modules and the high-voltage box as shown.
According to the number of battery layers used by the customer, the link harnesses are connected from top to bottom. Finally, self- locking plug nut to complete the circuit.
The wiring harness must be connected in the sequence shown in Figure 9.1-9.2-9.3. Otherwise, risks may arise.

DANGER

Make sure you hear the connection terminal harness and self-locking plug nut click into the slot to secure the connection.
The clicking sound applies to both the battery interconnect cables AND the self locking nut”

Single cluster connection method:

Connect the power through P+ and P-
Connect the first High-voltage box Link Com Terminal to the inverter BMS port for communication beween inverter and battery.

Multi-clusters connection method:

Connect the first High-voltage box Link Com Terminal to the inverter BMS port for communication beween inverter and battery.
Then the P+ and P- ports of the connected single cluster are combined for output through the combiner box.

Danger| Ensure power cables are installed with the correct polarity.
A dangerous situation may arise if the polarities are reversed.
---|---
Danger| Do not create a short circuit between the positive and negative terminals of the battery. Ensure the polarity is correct during installation.
Warning| Incorrect communication cable connection will cause the battery system to operate in unexpected ways which may lead to system failure.

Disassembly, Addition of New Modules, or Replacement of Units

DANGER

Regardless of whether a battery module is being added or whether the battery system is being temporarily or permanently disassembled, certain sections of the battery system will be required to be disconnected and taken apart. Proceed as follows:
