Hardware operation

3.3 Communication with the inverter

The Data Storage window (Figure 3-9) is used to start, stop and configure the data archiving function of

the PowerProtect solar system. The data to be archived, the scan rate, the data length and archiving path

are specified in this window.

The scan rate (t

scan

> xxs) and the data length, i.e. the period for which the data will remain stored in the

archive file, can be freely selected (t

file

> 1 day). Furthermore, you can define the number of panes and

their content to suit your own needs by means of parameters in a configuration file. In the default

configuration, the following panes are available:

• Weather conditions

• PV generator

• Mains interface

• Energy

The archiving function in PowerProtect solar is purely a data archiving function, but does not allow

visualization or analysis of data.

Weather conditions

All weather data available for the PV system are displayed in the Weather Conditions window. Check the

boxes for the values that you want PowerProtect solar to store. You can select the following data (*

provided the relevant sensors are installed in the PV system):

• Temperature *

• Wind velocity *

• Global insolation *

PV Generator

The PV Generator window displays all available information about the PV generator. Check the boxes for

the values that you want PowerProtect solar to archive. You can select the following data (* provided the

relevant sensors are installed in the PV system):

• Module temperature *

• Module irradiation *

• Voltage (V) PV Generator

• Current (I) PV Generator

• Power (P) PV Generator

Mains Interface

The Mains (Grid) Interface window displays all the available data about the grid connection. Check the

boxes for the values that you want PowerProtect solar to archive. You can choose from the following

values:

• Phase voltage

• Phase current

• Phase reactive current

• Phase apparent power

• Total active power

• Total reactive power

• Total apparent power
