INSTALLATION
Unpacking and Inspection
Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You
should have received the following items inside of package.
Unpacking and Inspection
Install the fixing component on the battery, then mark the position of the fixing component
on the wall andinstal the expansion screw.
Connection between Batteryand Inverter
The positive and negative poles of the battery can be connected to the positive andnegative poles of the inverter accordingly. The connection ofthe communication lineneeds to be done according to the instructions ofthe inverter. Please contact themanufacturer for battery debugging. lf the batteries need to be connected in parallel, amatchingjunction boxis required for connection.
OPERATION
Press the batterylow voltage switch to turn on the battery
Reset Button Description
1.When the BMS is in sleep state, press the button for 3~6S and release it. The protection board is activated, and the LED indicator turns on for 0.5 seconds from “RUN”.x
2.When the BMS is in the active state, press the button 3~6S and release it, the protection board will be hibernated, and the LED indicator will turn on for 0.5 seconds from the lowest power indicator.
3.When the BMS is in the active state, press the key 6~10S and release it, the protection board is reset, and all the LED lights are extinguished at the same time.
4.When the BMS is in the active state, press the button three times with in 5s, and the BMS can be automatically coded again.
Buzzer Logic
When fault occurs, ring 0.25s per 1s;
When protecting,ring 0.25s per2s (except over-voltage protection);
When alarming,ring 0.25s per 3s(except over-voltage alarm);
The buzzer function can be enabled or disabled by upper computer, and it is disabled by factory default.
Sleep and Wake Up
- Sleep
- If any of the following conditions are met, the system enters hibernation mode:
- 1)Monomer or overall overrelease protection is not removed within 30 seconds.
- 2)Press the button (3~6S) and release the button.
- 3)At the same time, no communication, no protection, no balance, no current, and the duration reaches the sleep delay time.Before entering hibernation mode, ensure that no external voltage is connected to the input terminal. Otherwise, the hibernation mode cannot be entered.
- Wake Up
- If any of the following conditions are met, the system exits the hibernation mode and enters the normal running mode:
- 1)Connect the charger, and the output voltage of the charger should be greater than 48V.
- 2)Press the button (3~6S) and release the button.
- 3)With 485,CAN communication activation.
- Note: After the single or overall overrelease protection, it enters sleep mode, wakes up periodically every 4 hours, and starts charging, and discharging MOS. If it can be charged, it will exit the resting state and enter normal charging;
