Display field only, not editable: Module string numbers
Module field
Module field numbers can be used to assign the same types of strings or
inverters. In the system monitoring, only strings or inverters with the same
module field number are offset against each other.
Each connected string is assigned to a module field. Module fields are
subdivided according to solar module type, angles of inclination and align-
ment. 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. Strings not
used must be switched off (switched to “0”)
Other module fields must be defined for modules with different alignments.
Each field is made up of at least two individual strings, which monitor each
other.
Example:
An installation with 23.6 kWp is divided into 3 × SMA SB5000TL and
2 × 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, with 32° inclination, 0° South deviation.
All connected strings allow mutual monitoring, the strings in module field 1
allow multiple monitoring, and the two strings in module field 2 mutual mon-
itoring.
