48V100Ah - Energy Storage Lithium Battery Module - User Manual
3.7
Setting the Battery Address: After the preceding operations are complete, set the IP address of the battery
connected to the inverter to 1, and set other IP addresses from 2 until all the Settings are complete.
Note:
The address of the battery must not be the same. Otherwise, communication will be affected.
3.8
Check that all connections are correct and firm.
3.9
Start the inverter to charge the battery. In normal state, all the batteries will be activated and enter the working
mode.
4.1 Preliminary determination steps:
The battery can be turned on, but red light is lighting, and cannot charge or discharge. If the red light is lighting, that
means system is abnormal, please check values as following:
Temperature:
Above 55
º
C or under -20
º
C, the battery could not work.
Solution: to move battery to the normal operating temperature range between -20
º
C and 55
º
C.
Current:
If current is greater than 110A, battery protection will turn on.
Solution: Check whether current is too large or not, if it is, to change the settings on power supply side.
High Voltage
: If charging voltage above 54V, battery protection will turn on.
Solution: Check whether voltage is too high or not, if it is, to change the settings on power supply side.
Low Voltage
: When the battery discharges to 44.5V or less, battery protection will turn on.
Solution: Charge the battery for some time, the red light turn off. Excluding the four points above, if the faulty is still
cannot be located, turn off power switch of the battery and repair.
4.2 The battery cannot be charged or discharged.
4.2.1
No charging: First check that the charging voltage of the charging device is normal, if the charging voltage is
normal (52.5V-54.75)V), and then use the upper computer to connect with the battery, read the detailed data of the
battery, check whether the voltage and temperature of the single battery are normal, if the charging equipment is
normal, the general reason for not charging is: the single charging over voltage protection or high temperature
protection.
4.2.2
Fail to discharge: Disconnect the battery from the load and measure whether the voltage of the battery is
normal, If the battery has no output voltage, press the Reset button to sleep the battery first and then wake up
(restart the battery), and test the battery voltage again. If the battery voltage returns to normal, it indicates that the
battery is protected, Check the load.
