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
