Logging

General

At regular intervals, Fronius Datamanager saves the real-time data of all inverters as well
as all sensor cards and Fronius sensor boxes integrated into the system. The save interval
can be defined in a range of 5 - 30 minutes.
The data can be easily edited, archived, and viewed with a PC or laptop using the "Fronius
Solar.access" software.

Memory capacity

Fronius Datamanager has a memory capacity of up to 5 years and 7 months for a photo-
voltaic system with one inverter and a save interval of 15 minutes.
However, the memory capacity is reduced depending on the number of inverters and/or
Fronius sensor cards/boxes that are integrated into the system.

Determine logging points for inverters and Fronius sensor cards/boxes
Logging points per day =
Logging duration [min]
- For inverter: e.g., 14 hours = 840 minutes
- For Fronius Sensor Card/Fronius Sensor Box: 24 hours = 1440 minutes
Calculate the total logging points
Total logging points =
= (number of inverters x logging points per day) + (number of Fronius Sensor Cards/
Boxes x logging points per day)
