18�5�6 Module Fields
Each connected MPP tracker is assigned to a module field. Module fields are subdivided according to the
type of the solar module, angles of inclination and alignment. If all modules within a system are of the same
type and have the same alignment, only one module field, e.g. "1", is defined. MPP trackers that are not
used must be switched off (switched to "0"),
Additional module fields need to be defined for modules with different alignments and module types.
Ideally, each field should be made up of at least two individual MPP trackers, which monitor each other.
The module fields are used for the performance monitoring. In contrast, plant groups (Chapter 19.2) are
used for the commercial calculations.
Example module fields:
A plant with 23.6 kWp is divided into:
3 x SMA SB5000TL and
2 x SMA SB2500.
18 kWp is located on a barn roof with 30° inclination, 20° South-East deviation, and 5 kWp on an adjoining
garage roof, 32° inclination, 0° South deviation.
This results in two module fields according to the following table:

18�6 Changing the device order
The sequential order of the inverters and other devices is determined during inverter detection. They are
normally sorted by their serial number or communications address.
The order can be changed through drag and drop from the Configuration | Devices | Configuration |
Order menu.
