PRODUCT OVERVIEW

Brief Introduction

SUN-BATT-5.32 is a lithium battery with an operating voltage range between 45.6~56.16V. It is designed for
residential energy storage applications and works together with a 48v battery hybrid inverter. SUN-BATT-5.32 is not suitable for supporting life-sustaining medical devices.
SUN-BATT-5.32 has built-in BMS (Battery Management System), which can manage and monitor cells information including voltage, current and temperature. Besides that, BMS can balance cells charging to extend cycle
life. BMS has protection functions including over-dis- charge, over-charge, over-current and high/low temperature;
the system can automatically manage charge state, discharge state and balance state.
Multiple SUN-BATT-5.32 can be connected in parallel to expand capacity and power, 8 SUN-BATT-5.32 can be connected in parallel

BATTERY POWER AND COMMUNICATION CONNECTIONS

Parallel Cascade Connection

Applicable scenario:

  • PCS with 100A charge/discharge current connect to SUN-BATT-5.3

Power Cable Wiring Instructions

Each SUN-BATT-5.32 has two pairs of power cable terminals, two P+, and two P-. The connection terminals of each pair have the same function.
Single Module
In a single module application, any of the terminals of each pair can be used.
Parallel System
Multiple batteries can be connected in parallel to expand the capacity and power. When using multiple batteries in parallel, one will operate as a master and the others as slaves. One of the Master pack P+ terminals should connect to the PCS, and the other should connect to another battery for capacity expansion.
One of the P- terminals of the last Slave pack should connect to PCS, and the other should connect to another battery for capacity expansion.
For the other Slave packs, each P terminal should be connected to another battery’s terminal.

PLEASE NOTE
The connection to the protection devices should use the P+ terminal from the Master pack and the P- terminal from the last Slave pack.

Communication Cable Connections

The Master battery can automatically identify the Slaves batteries connected in parallel using its internal software control. The communication terminals Port In and Port Out (RJ45 port) are integrated with the signal for automatic coding function.

PLEASE NOTE

All parallel power cables should be of the same length.
The following describes the connections of a system with four batteries packs, one Master, and three Slaves.

  • The CAN communication port of the Master pack should connect to PCS;
  • Port In from the Master pack should not be connected;
  • The Port Out from the master PACK should connect the Port In of the first slave PACK using a parallel communication wire;
  • The Port Out of the first Slave pack should connect to the Port In of the second Slave PACK;
  • Following the same pattern, the Port Out of the second Slave pack should connect to the Port In of the third Slave PACK;
  • The Port Out of the third and last slave PACK should not be connected.
Busbar Connection

Applicable scenario:

  • PCS with 200A charge/discharge current connect to SUN-BATT-5.32.


PLEASE NOTE
All parallel power cables should be of the same length:
(L1 = L2 = L3 = L4 = L5 = L6 = L7 = L8)

  • You are advised to use the EV power cables with minimal size of 25 mm2 or 3AWG (600V, 125A) and length min.1500mm.
  • The P+ and P- power line between the busbar and the PCS should be able to support 200A rated current, You are advised to use the EV power cable with size min. 50 mm2 or 0AWG (600V, 210A).
  • Before assembling Power cable, label the cable polarities correctly to ensure correct cable connections and identification.
  • The power cables installation and connection must be carried out by trained professionals.

-10~25ºC| 5%~70%| ≤12 months| 30%≤SOC≤60%
25~35ºC| 5%~70%| ≤6 months| 30%≤SOC≤60%
35~45ºC| 5%~70%| ≤3 months| 30%≤SOC≤60%
Above 45ºC| /| prohibit| /

Recharge Requirements When Over Discharged

Over discharged (90% DoD) battery should be recharged according to following table, otherwise over discharged battery will be damaged.

Recharge conditions when battery is over discharged

Storage Environment Temper – ature| Storage Time| Note
-10~25ºC| ≤15 days| Battery Pack disconnected from PCS
