Boot and sleep mode
Sleep mode: the battery will be in sleep mode if any of the following conditions are met

1. The battery or battery pack over-discharge protection lasts for 30 seconds and is not released.

2. Press the power on / off button for 3 seconds and release.

3. The minimum voltage of the battery is lower than the “sleep voltage” setting in the setting, without charging and discharging.

4. Standby for more than 24 hours without charging and discharging.

5. Switch to the upper computer for sleep manually.
   Wake up: the battery will exit sleep mode if any of the following conditions are met

6. Charger is plugged in; The charger voltage is greater than 48V.

7. Press the power on / off button for 3 seconds and release.

8. Plug in the communication cable and open the upper computer software (not available if it is under over-discharge protection).

Note:
If over-discharge protection is enabled, the battery will be in sleep mode. The battery will wake up automatically every 4 hours and turn on the charge/discharge MOS. If charging is available, the battery will be charged, otherwise, it will return to sleep mode. If it has been awakened 10 times but cannot be charged, the battery will not wake up again automatically.

Communication Area

1. RS232: BMS can communicate with the upper computer through the RS 232 interface, to monitor various information about the battery, including battery voltage, current, temperature, status battery production information, etc. the default baud rate is 9600bps.
2. RS485: with a dual RS485 interface, you can view the information of the pack. The default baud rate is 9600bps. If it is necessary to communicate with the monitoring equipment through RS485, the monitoring equipment is used as the host, polling data according to the address, and the address setting range is 1 ~ 15.
3. CAN: CAN communication, baud rate 9600bps.
4. RS485 and CAN: The user can communicate with the inverter through these two interfaces.
5. RS485 add RS232: The users can connect to the computer through these two interfaces.
6. DCT: Dry contact interface.
7. Rst: reset button.
8. ADS: dial switch
