10.5 Frequently Asked Questions
10.5.1 Questions on the Off-Grid Inverter
Error F117 occurs when starting the off-grid inverter?
The loads connected to the stand-alone grid might be too great for the off-grid inverter.
• Switch some loads off.
A permanent short-circuit might exist in the stand-alone grid.
• If you are a skilled person, check whether there is a short-circuit at connection AC1 and in
the stand-alone grid.
The off-grid inverter does not deactivate even though you have opened the
switch-disconnector of the BatFuse?
The off-grid inverter might still be supplied from the AC side.
• Switch off all AC sources and disconnect them from the off-grid inverter.
The off-grid inverter does not switch to silent mode?
Another function might have a higher priority than silent mode, e.g. equalisation charge or full
charge.
