10 shows “Last Week” measured data,
presented in values. The red bars show the
minimum voltage, the yellow bars indicate the
maximum voltage. The data for “Last Month” and
“Last Year” can also be obtained. These diagrams
will be displayed by using the weekly or monthly
averages.

Figure 5-11: Average data
The System Performance informs you how well the
load was supported by the system produced energy.
The following questions are answered:
• Is the PV generator able to supply the system with
enough energy to power the load(s)?
• Is the battery being handled well enough to ensure
maximum lifetime?
• Is the energy reserve capacity (battery) large
enough to power the system?
“Average data” shows average values to compare with,
enabling you to discover possible disturbances in the system.
