SMA Solar Technology AG
Power supply failure when the SMA Fuel Save Controller is restarted
Before restarting the SMA Fuel Save Controller, the SMA Fuel Save Controller and PV power plant must be stopped.
It can take a few minutes for the SMA Fuel Save Controller and PV power plant to stop because the PV inverters
have to reduce their output power slowly. If the PV inverters are still feeding energy to the grid when the SMA Fuel
Save Controller is restarted, this may cause failure of the power supply.
• Once the SMA Fuel Save Controller has stopped, wait until the PV inverters have reduced their output power to
zero. This can take several minutes.
Procedure:
1. Choose the menu Parameter Files via the page and menu selection.
2. Choose the parameter file with the required system settings via the dropdown list File database.
3. In the Reboot with a selected file bar, select the [Reboot] button.
