Frequently asked questions about Siemens inverters

How to reset Siemens inverters?

There are three main ways to reset Siemens inverters:

Method 1: Turn off the power and turn it back on

• The simplest and most common way to reset the inverter.
• How to do it:
  • Turn off the power supply to the inverter.
  • Wait about 30 seconds to 1 minute.
  • Turn the power supply back on.

Method 2: Press the Fn button

• Some Siemens inverters have an Fn button to reset the fault.
