2. PRODUCT OVERVIEW
2.1. Brief Introduction
SUN-BATT-5.12 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-5.12 is not suitable for supporting life-sustaining medical devices.
SUN-BATT-5.12 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-5.12 can be connected in parallel to expand capacity and power, 8 SUNBATT-5.12 can be connected in parallel at most.

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 packing 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.
3.1.2. 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. Parallel Cascade Connection
Applicable scenario:
PCS with 100A charge/discharge current connect to SUN-BATT-5.12.
4.1.1. Power Cable Wiring Instructions
Each SUN-BATT-5.12 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.
The connection to the protection devices should use the P+ terminal from the Master pack and the P- terminal from the last Slave pack.

4.2. Busbar Connection
Applicable scenario:
PCS with 200A charge/discharge current connect to SUN-BATT-5.12.
Page | 18Hybrid Inverter | Installer Manual
Page 19
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.
4.3. Parallel Cascade Connection
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.
All parallel power cables should be of the same length.
The parallel system supports an operation with up to 4 parallel connections. 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.
