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 informa-
tion 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 temper-
ature; 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 SUN-BATT-5.12 can be
connected in parallel at most.
