9.1 Sunny Island Inverter Behavior Under Fault Conditions
Display of errors, warnings, and events
Pending warnings and errors are shown automatically on the display of the Sunny Remote Control until the cause of the
warning or error is no longer logged by the Sunny Island or has been acknowledged. Events are logged by the
Sunny Island. The following menus log warnings, errors and events:
• 410# Error active - display of currently pending warnings and errors
• 420# Error history - warning and error history
• 430# Event history - events history
• In systems for increased self-consumption and battery backup systems: 440# Error Grid - history of the last five utility
grid errors
Structure of display numbers
Each error and each event has a unique three-digit display number that is determined based on the parameter or
measurement value assignment. Events and errors use the same number range:
• 1xx - Sunny Island
• 2xx - Battery
• 3xx - Generator or utility grid
• 4xx - Generator
• 5xx - Utility grid
• 6xx - Relay
• 7xx - System
• 8xx - External devices and components
• 9xx - General
Error Levels
The Sunny Island distinguishes between five different levels of errors, each requiring different user interaction.
Meaning of abbreviations
F indicates an error, W a warning, and E an event.
In the event of an error, the display shows whether the error has come or gone using ! for "Set" and C for "Clear".
