No. Name Functions Remark
1 SOC Indicators for capacity
There are four green LED lights in front panel indicating SOC. SOC is short for state of charge. Each SOC LED light represents 25% of rated capacity.
2 ALM Indicator for alarms There is one red LED light in front panel indicating alarms.
3 RUN Indicator for running status
There is one green LED light in front panel indicating running status.
4 ADDSystem communication address
ADD is applicable to modules connected in parallel. ADD consists of four binary bits
5 RS-232Up-link communicationport
Upload data. Contents of data transmit include BMS parameters, battery running status, alarms, etc. Generally, speed rate of RS-232 is 1200bps. RS232 up-link communication can be available for the battery module with a binary communication address of0000 (Master PACK).

No. Name Functions Remark
6 RS-485Software communicationport
It is adopting RS485 series port communication pattern to upload data. Communication of modules connected in parallel (Slave PACKs) is available through RS 485. Data of slave PACKs will be transmitted to Master PACK.
7 RESET Reset button Press RESET button when abnormity occurs to assure stability of battery performance.
8 Dry contact Indicator for running status Used for battery protection
9 Switch ON/OFF switch When turn-off, battery get into sleep mode, and cut-offoutput, the alarm output also will be stopped.
10 Battery Output Nominal 48V output Using terminals with four cores. Polarities are +, -, +, -
from left to right. The two ‘+’ and ‘-’ are equal relatively.
Executive Summary
Site Type: OutdoorSite Conditions:1. Roadside /Outdoor Cabinet2. Bad Grid3. Limited area
Technical AnalysisA. LITHIUM ION BATTERY4. Longer life of existence due to more number of cycles.
Approximately 10-year life span5. Faster charging time6. Outdoor installation is more ideal because of its high thermal
capacity7. Less space consumption (typical size is twice smaller than a 1-
bank VRLA battery)8. Smarter. It can be monitored individually through its own BMS9. Safety. Does not contain toxic materials and no gas emission10.Higher energy transfer efficiency
B. VRLA BATTERY11.Less cost at same capacity12.Availability in higher Ampere-Hour capacities
