(3) Inverter type (DATCOM code)
(4) Logging interval in seconds
(5) Energy in watts per second, relative to the logging interval
(6) Inductive reactive power
(7) Capacitive reactive power
(8) Average values during the logging interval (AC voltage, AC current, DC

(9) Additional information
Data volume and
storage capacity
A USB flash drive with a storage capacity of 1 GB can record logging data for
roughly seven years at a logging interval of five minutes.
CSV file
CSV files can only store 65,535 lines (data records) (up to Microsoft® Excel 2007;
there is no restriction from this version onwards).
At a five-minute logging interval, the 65,535 lines will be written within approx-
imately seven months (CSV data size of approx. 8 MB).
