PRODUCT OVERVIEW

Brief Introduction
SUN-BATT-5.32R is a lithium battery with an operating voltage range between 45.6 and 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 a built-in BMS (Battery Management System), which can manage and monitor cell information including voltage, current, and temperature. Besides that, BMS can balance cells charging to extend cycle life. BMS has protection functions including over-discharge, over-charge, over-current, and high/low temperature; the system can automatically manage the 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.

Interface Introduction

Switch ON/OFF

Switch ON

For single SUN-BATT-5.32R, switch the ON rocker switch, then long press (more than 3 seconds) the ON/OFF button on the front panel, LED will flash, then battery will operate normally. L1 to L6 shows battery SoC, L7/L8 shows battery status.
For multiple SUN-BATT-5.32R in parallel, switch the ON rocker switch on all batteries, and long press (more than 3 seconds) ON/OFF button of the MASTER battery, LED will flash, the battery system will automatically encode and assign ID to each slave battery, then battery system will operate normally.

Switch OFF

Press the start button of the Master PACK for more than 3s and then release the button, the master pack will shut down after all slave packs shut down(Sleep mode) .
For a single SUN-BATT-5.32R, switch OFF the rocker switch.
For multiple SUN-BATT-5.32R in parallel, switch OFF the rocker switch on the MASTER battery first. Then switch OFF the rocker and switch on all slave batteries

INSTALLATION GUIDE

Checking Before Installation

Checking Outer Packing Materials
Packing materials and components may be damaged during transportation. Therefore, check the outer packaging 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.

Checking Deliverables

After unpacking the battery, check whether the 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.

Tools

Installation Requirements

Installation Environment Requirements

Install the battery in the indoor environment.
Place the battery in a secure location away from children and animals.
Do not place the battery near any heat sources and avoid sparks.
Do not expose the battery to moisture or liquids.
Do not expose the battery to direct sunlight.

Installation Carrier Requirements

Only mount the battery on a fire-resistant building. Do not install batteries on flammable buildings.
The battery is quite heavy, make sure the wall/ground can meet the load-bearing requirements.

Installation Instructions

Dimensions

Installation Steps (Rack Mounted)

STEP 1
Remove the handle from the battery.

STEP 2
Install Support frames at the four corners of the battery.

STEP 3
The battery with the support frame is stacked up and down.

Installation Steps (Wall Mounted)

Minimum mounting distance requirement (Wall Mounted):

STEP 1
Drill the hole with a 10mm drill bit as follows and fix the wall bracket to the wall.

STEP 2
Install the wall-hanging bracket.

STEP 3
Hang the machine on the wall hang the back plate and tighten it.

BATTERY POWER AND COMMUNICATION CONNECTIONS

Wiring Steps

STEP 1
Connect the battery to the ground.

STEP 2
Connect the battery power line.

STEP 3
Connect the communication lines.

Parallel Cascade Connection

Power Cable Wiring Instructions
Each SUN-BATT-5.32R 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 slave 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. The following describes the connections of a system with four battery 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.

Wiring Diagram for Parallel Cascade Connection
When multiple batteries are connected in parallel, follow the following wiring mode.

MAINTENANCE

Recharge Requirements During Normal Storage
Battery should be stored in an environment with a temperature range between -10°C ~ +45°C and maintained regularly according to the following table with 0.5C (25A) current till 40% SoC after a long storage time.

Recharge Conditions When In Storage

Recharge Requirements When Over Discharged
