battery module for capacity expanding. For each single module, each
terminal can achieve charging and discharging function. For power cables
uses water-proofed connectors. Keep pressing this Lock Button while
pulling out the power plug.
2.5. Sleep and Wake up
2.5.1 Sleep
When any of the following conditions is met, the battery enters the low-power mode:
1) Under voltage protection is not released within 30 seconds.
2) Press the reset button for 3 seconds and then release the button.
NOTE:
 If there are other batteries in the output state in parallel application scenario, the current battery
cannot be set to sleep through the reset button at this time, because it will be charged and awakened by other
batteries with normal output.
3) The lowest cell voltage is lower than the sleep voltage, and the duration reaches the sleep
delay time (while meeting the requirements of no communication, no protection, no
equilibrium, and no current).
4) Standby mode lasts for more than 24 hours (no communication, no charge and discharge,
no mains power, minimum cell is less than 3.2V).
5) Forced shutdown from the HOMEGRID externally connected Ems Tools.
Before entering sleep, make sure no charger is connected, otherwise it will not be able to enter
low-power mode.
2.5.2Wake up
When the system is in the low-power mode and any of the following conditions is satisfied,
the system will exit the low-power mode and enter the normal operation mode:
1) Connect the charger, and the output voltage of the charger must be greater than 48V.
2) Press the reset button for 3 seconds and release the button.
3) Connect the communication line and open the HOMEGRID Ems Tools (if enters sleep
mode due to over-release protection, and this method cannot wake up the battery).
4) Use the power software switch.
NOTE:
After battery over-discharge protection, it enters the low-power mode, wakes up at a regular time every 4
hours, and starts open switch to charging or discharging. If it can be charged, it will exit the sleep mode and enter
the normal charging state. If the auto wake up fails to charge for 10 consecutive times, it will no longer auto wake
up. When the system is defined as the end of charging, and the recovery voltage is still not reached after 2 days /48h
standby time (standby time set value), it is forced to resume charging until the end of recharging.
Page 11 Chapter 2: Introduction

Compact Series HOMEGRID Technical
2.6. Forced discharge mode
When the battery is in under voltage protection sleep mode and the minimum battery voltage is
greater than 2.0V, press and hold the power button, the display will light up and flash until the
display stops flashing and releases the power button, and the battery will enter the forced
discharge mode for 5 minutes. In the forced discharge mode, if the battery is charged, it will exit
the forced discharge mode and switch to the normal mode. If the discharge current exceeds 20A
or there is no charging current within 5 minutes, the battery will enter the sleep mode again.
2.7. Automatic parallel
With automatic parallel function; when the slave battery (address > 1) is powered on, the
charge and discharge switch is in disconnect state. When the voltage difference between the
slave battery and master battery is less than the condition of "the minimum voltage difference
between the slave and the master", the master sends the command to the slave. After the slave
receives the command from the master, the charge and discharge switch will be connected and
the slave is integrated into the master system to complete the parallel operation.
