Azimuth Angle (Orientation)
In the Northern hemisphere, the azimuth angle indicates by how many degrees the module surface
deviates from the compass point South. In the southern hemisphere, it indicates the deviation from the
direction North. The azimuth angle is counted from south (0°) via west (+90°) with positive values
and from south (0°) via east (‒90°) with negative values.
DHCP
DHCP is short for "Dynamic Host Configuration Protocol" and is a server service with which devices
are automatically integrated into a network. If no DHCP is activated in the network (e.g. on the router),
devices must be integrated into the network manually. In order to do this, an IP address and subnet
mask that are suitable for the network must be created manually for the device to be integrated, for
example.
Inline Frame
An inline frame is an HTML element for structuring websites. It is used to display another website's
content on a website. An inline frame is being inserted in the website's source code that contains the
website's address that is supposed to be embedded.
kWp
See peak power.
Log File
A log file is an automatically run log of events on a computer system. A log file contains errors that
occurred during operation of the computer system, for example.
Module Group
A module group in Sunny Portal consists of micro inverters with PV modules that fulfill the following
criteria:
• Same manufacturer
• Same module type
• Same azimuth and tilt angle
Nominal Power (kWp)
See peak power
Peak Power (kWp)
The peak power is the maximum power output calculated for a PV module under STC (Standard Test
Conditions).
The peak power is measured in watt peak (Wp), kilowatt-peak (kWp), or megawatt-peak (MWp).
Peak power is also called nominal power.
STC: standard test conditions in the laboratory under which the electrical characteristics of a
PV module are measured. This allows different PV modules to be compared with one another.
The PV modules are exposed to a vertical irradiation of 1,000 W/m
2
, an ambient temperature of
+77°F (+25°C), and a wind speed of 1 m/s. The electrical characteristics are then measured.
The test conditions are designed to correspond to the ideal ambient conditions for operation of an
installed PV module.
