Description
SOC
Parameters
Disabled
If it is enabled, the local controller controls charge and
discharge power of the system according to battery SOC
information read from the BMS, so as to keep the battery SOC
operating within the set section.
SOC upper limit 1 (2) level: battery charge SOC 1 (2) level
upper limit
SOC lower limit 1 (2) level: battery discharge SOC 1 (2) level
upper limit
SOC lower limit 1 (2) recovery: battery lower limit 1 (2) level
alarm recovery value
SOC hysteresis control
SOC control delay time (s): delay of triggering battery SOC
alarm
SOC control recover time (s): SOC alarm recovery delay

Parameters
Disabled
If it is enabled, the local controller controls charge and
discharge power of the system according to battery SOC
information read from the PCS, so as to keep the battery
voltage within the set section.
 In case of grid connection, the battery SOC or the voltage
charge and discharge sections is at the lower limit 1 to the
upper limit 1.
 In the off-grid case, the battery SOC or the voltage section is
above the lower limit level 2.
Vbat upper limit 1 (2) level: battery charge voltage 1 (2) level
upper limit
Vbat lower limit 1 (2) level: battery discharge voltage 1 (2) level
