Information on this Document
This document is valid for:
• STP 60-10 (Sunny Tripower 60) from software version 1.80
• STP 60-JP-10 (Sunny Tripower 60) from software version 1.80
• SHP 75-10 (Sunny Highpower Peak1) from software version 1.90
• SHP 75-JP-10 (Sunny Highpower PEAK1) from software version 2.0
This document is intended to help the user get a better understanding of the functionality of the inverter. The
descriptions refer to the parameter IDs which can also be found in the "Settings report".
The value ranges indicated in the following sections do not necessarily refer to the permissible ranges in accordance
with the applied standards, but are to reflect the performance of the inverter. All adjustable parameters have the same
indicated ranges and increments. Since not all parameters are used by all standards, the parameters that are not used
will be deactivated in the file "Inverter settings".

Grid Protection Settings
The following parameters for grid connection settings are saved in the inverter and only used here. The settings are
divided into groups. The groups reflect the various grid management services.
All requirements for grid protection settings are set at the inverter connection point.
2.1
Nominal Voltage
This parameter refers to the nominal grid voltage of a country. In most countries, only one official grid voltage is valid.
For countries with several official grid voltages, additional grid codes are provided so that the user is able to set the
grid voltage requested by the grid operator.
Parameter name
Setting range
UNOM
220 Vac to 277 Vac (L-N)
2.2
Nominal Frequency
The nominal frequency can either be 50 Hz or 60 Hz, and for the most part only one of the two is used. For countries
where both frequency values are used, additional grid codes are provided so that the user is able to set the nominal
frequency requested by the grid operator.

Setting range
FNOM
50 Hz or 60 Hz
2.3
Voltage-Dependant Disconnection
2.3.1
Disconnection due to Undervoltage
The undervoltage disconnection capability has two parameters in a set, the first parameter is the magnitude, which is
given in voltage, the second is the trip time, which is given in seconds. Undervoltage disconnection works in the way
that in case of grid failure below the value stated in
UMIN
, the inverter stays connected to the grid for the time period
stated in
T_UMIN
. After this time has elapsed, the inverter must disconnect from the utility grid. Depending on the
applied standard, these two values can either be a maximum, minimum or mean value. Refer to the relevant standard
to see which of the three key values is used in your file.
