2 System Information
2.1 Product introduce
SG-B5KW is a 51.2V DC battery storage system based on lithium-iron phosphate battery, which is one of the new energy storage products developed and produced by SolarMG. It can be used to support reliable power for various types of equipment and systems. SG-B5KW is especially suitable for those application scenes which required high power output, limited installation space, restricted load-bearing and long cycle life.
2.2 Specification
2.2.1 Battery Module

Cable Panel

ON/OFF

1. ON
   For single Battery Module, Long press (more than 3 seconds) ON/OFF button, Normal LED will be lighted in the front panel then battery will operate normally. L1 to L6 shows battery SOC, L7/L8 shows battery status.
   For multiple Battery Modules in parallel, long press (more than 3 seconds) ON/OFF button of MASTER battery (Which connect with inverter), normal LED i will be lighted, battery system will automatically encode and assign ID to each slave battery, then battery system will operate normally.

2. OFF
   Press ON/OFF button of Master PACK (which connect with inverter) more than 3s, LED will flash in the front panel and then release the button, the master pack will shut down after all slave packs shut down (Sleep mode).
   For single Battery Module, Long press (more than 3 seconds) ON/OFF button, LED will flash in the front panel and then release the button, the battery will shut down.
   In the system with inverter, there is an air switch between inverter and battery system, normally the air switch keeps off-state if the system does not work.

COM Port
CAN / RS485/RS232 Communication Terminal (RJ45 port), CAN/RS485 connect to inverter, follow CAN / RS485 protocol.
RS232 Communication follow RS232 protocol, for manufacturer or professional engineer to debug or service.

Link in/Link out
Link in/Link out are used for the communication between battery piles. The battery pack close to the inverter as the master, others are the slave pack.
