PRODUCT OVERVIEW
2.1 Brief Introduction
SUN-BATT-15.97 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-15.97 is not suitable for supporting
life-sustaining medical devices.
SUN-BATT-15.97 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-15.97 can be connected in parallel to expand capacity and power, 8
SUN-BATT-15.97 can be connected in parallel at most.

2.2 Interface Introduction
2.2.1 Switch ON/OFF
1. Switch ON
For single SUN-BATT-15.97, switch ON rocker switch (near positive/negative connector),
then long press (more than 3 seconds) ON/OFF button on 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-15.97 in parallel, switch ON rocker switch on all batteries, long press
(more than 3 seconds) ON/OFF button of MASTER battery, LED will flash, battery system
will automatically encode and assign ID to each slave battery, then battery system will
operate normally.

3.1 Checking Before Installation
3.1.1 Checking Outer Packing Materials
3.1.2 Checking Deliverables
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.
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.
