2. PRODUCT OVERVIEW
2.1. Brief Introduction
SUN-BATT-5.32R 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-5.32R
is not suitable for supporting life-sustaining medical devices.
SUN-BATT-5.32R has built-in BMS (Battery Management System), which can manage and monitor cells infor-
mation 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-5.32R can be connected in parallel to expand capacity and power, 8 SUN-BATT-5.32R can
be connected in parallel at most.

3. INSTALLATION GUIDE
3.1. Checking Before Installation
3.1.1. Checking Outer Packing Materials
Packing materials and components may be damaged during transportation. Therefore, check the outer pack-
ing materials before installing the battery. Checking the surface of packing materials for damage, such as holes
and cracks. If any damage is found, do not unpack the battery and contact the dealer as soon as possible. You
are advised to remove the packing materials within 24 hours before installing the battery.
3.2. Checking Deliverables
After unpacking the battery, check whether deliverables are intact and complete. If any damage is found or any
component is missed, contact the dealer.
The below table shows the components and mechanical parts that should be delivered.

4. BATTERY POWER AND COMMUNICATION CONNECTIONS
4.1. Wiring Steps

SUN-BATT-5.12R | User Manual18
Each SUN-BATT-5.32R has two pairs of power cable terminals, two P+, and two P-. The connec- tion 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 bat-
teries 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.
4.2. Parallel Cascade Connection
4.2.1. Power Cable Wiring Instructions
The Master battery can automatically identify the Slaves batteries connected in parallel using its internal soft-
ware control. The communication terminals Port In and Port Out (RJ45 port) are integrated with the signal for
automatic coding function.
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 rst slave PACK using a parallel
communication wire;
The Port Out of the rst 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.
4.2.2. Communication Cable Connections
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.
