Parameter 148: Serial number
Menu: Device configuration
Unit: ---
Resolution: 1
Default setting: 0
Password level: 4
Parameter 148 displays the serial number of the inverter.
Parameter 161: Waiting time grid okay
Menu: Safety/Basic settings
Unit: sec
Resolution: 1
Default setting: 30 sec
Password level: 2
Parameter 161 sets the time that must elapse following a grid fault (grid voltage or grid frequency not
OK) before the inverter reconnects to the grid.
For Germany (VDE 0126), a delay of 20 sec. is stipulated. Other settings may be required in other
countries.

By setting bit 0 = "Take external energy meter into account" to 1, the yields and power values
recorded by the external energy meter are included in the cumulative installation values of the
following parameters:
P197 Total CO2 reduction (of installation)
P198 Energy total of installation
P199 Power of installation (AC output)
P221 Energy of installation today
• By setting bit 1 = "LCD constantly On" to 1, the LCD remains constantly switched on. If you
set this bit to 0, the LCD switches itself off after 20 minutes if no button is pressed.
• By setting bit 2 = "LCD-LED constantly On" to 1, the backlight of the LCD remains constantly
switched on. If you set this bit to 0, the backlight switches itself off after 2 minutes if no button
is pressed.
• By setting bit 3 = "Write fault 7 to fault memory" to 1, a fault with fault code 7 = "UDC too low"
is entered in the fault memory. If you set this bit to 0, this "fault" – which inevitably occurs
every day in the morning and evening, often repeatedly, due to the output of the PV generator
being too low – is not entered in the fault memory. This means the fault memory does not fill
up so quickly.
• By setting bit 4 = "Reset" to 1, the inverter performs a restart (reset).
• By setting bit 5 = "S0 pulses in SEJL" to 1, the "day yields" recorded by an external electricity
meter connected to the S0 pulse input are saved to the annual sensor energy logger instead
of the "sensor yields". This function enables the yields of an "external installation" to be saved
to the installation with Solutronic inverters. See also parameters 127, 128, 151, 222, 224 and
225.
• By setting bit 6 = "Adopt data for large display", this slave of an installation has the data for the
large display of a master written to it.
