connected to the grid in parallel.
2.5.2 Function description
The functions of PWS2-30M-EX are as follows:
Grid-tied discharging: The inverter is in inverting state, converts DC into AC that meets the
requirement of power grid department in installation region, and feeds the energy back to
the power grid.
Grid-tied charging: The inverter is in rectification state and transmits 3-phase AC to charge
the battery (pack) by the set charging mode.
Off-grid discharging: The inverter is in inverting state, converts DC into AC that meets the
requirement of power grid department in installation region, and provides power supply for
3-phase load in the micro-grid.
Data storage and display: Storage and operation information, operation record and failure
record are displayed on the LCD screen.
Communication function:
Standard RS-485 interface can be connected with monitoring device such as EMS,
BMS.
Standard Ethernet interface is used to communicate with upper computer to realize
such functions as remote control and remote software upgrading.
Reactive power configuration: Regulate the reactive power of the storage system.
FVRT : frequency/voltage ride-through, this function can be enabled or disabled, for
more information, please refer to UL1741 Supplement A or other similar rules about
Utility-Interactive Distribute Generators.
Soft-Start/Reconnection ramp rate : This function will apply when system suspend
happens caused by utility voltage abnormal, and reconnect after utility restore normal.
The default value is 2, twice of rated power per second, which means within 0.5
seconds the system restores to full output.
Anti-Islanding : enable or disable anti-islanding function. For more information, please
refer to UL1741 Supplement A or other similar rules about Utility-Interactive Distribute
Generators.
Volt/Watt: Available when activated and operating in discharge mode. When the
actual voltage is above the point, the active power will be regulated with the ramp rate.
The ramp rate is defined as multiple of set active power per 1% of rated voltage that
above the Volt/Watt point.
Volt/VAR: Available when activated and operating in discharge mode. In this mode,
Reactive power as a function of grid voltage. In Volt/Var mode, the Q configuration is
