19.2 Adjustable System Parameters
Parameters with the designation (Stby)
Parameters with the designation (Stby) can be changed immediately after pressing the [ENTER]
key. It may not be possible to correct incorrectly configured parameters quickly enough to prevent
these causing damage to your plant.
• Parameters with the designation (Stby) are to be changed only when the
Sunny Backup 5000 is in standby mode.
Configuring parameters via a computer or laptop
All parameters can be configured using a connected computer or laptop.
Therefore, you require a connected Sunny WebBox, a Sunny Boy Control, or the software
program Sunny Data Control (see Section 6.5 "Interface for external communication" in the
technical description of the Sunny Backup 5000).
