11. 4 Direct Data Acquisition from an Inverter
This chapter describes how to acquire, and save data from an inverter connected
directly to the PC, and how to send these to Sunny Portal. With a direct connection of
a PC to an inverter, the data can only be saved as CSV data (SUO format, SMA-Sunny
Online).
11.4. 1 Setting up the Data Filing Structure
The following describes the data filing structure for an inverter directly connected to the
PC.
1. Select "Options/Settings" or click on the "Settings" icon.
The "Settings" window opens.
2. Select "Data Storage“.
3. In the field "Retrieval cycle", you can change the frequency with which the data
from the inverter are fetched. At the "User" security level, 30 seconds is the preset,
at the "Installer" security level 15 seconds is the preset.
4. In the area "Capture", you can choose between two options for data registry.
- "All values" = the channels are read according to the interval set for the query
cycle, and the values are registered at this interval frequency.
- "Average value" = the channels are read according to the query cycle interval
setting, but its values are registered at intervals set in the menu "Averaging
over...". In all other channels the values most recently captured are recorded.
With this option one can reduce the amount of data considerably without losing
its significance.
