The ‘System frequency’ setting in the General settings menu of a Victron inverter is used to specify the output frequency of the inverter.
The frequency, measured in Hertz (Hz), refers to the number of times the current changes direction per second. In many parts of the world, the standard electrical grid frequency is either 50Hz or 60Hz.
-
50Hz: This frequency is common in Europe, Asia, Africa, and Australia. Devices designed for these regions are built to operate optimally with a power supply at this frequency.
-
60Hz: Used predominantly in North America and parts of South America. Electrical equipment manufactured for these regions expects this frequency.
The importance of setting the correct system frequency lies in ensuring compatibility with your connected devices. Electrical appliances are designed to work with the frequency standard of the region they were sold in. Using the wrong frequency can result in inefficient operation, increased wear, or even damage. For instance, an electric motor designed for 50Hz may run faster and hotter if supplied with 60Hz, which could reduce its lifespan.
When you set the ‘System Frequency’ of your inverter, you are defining the frequency of the AC power it generates. This should match the frequency for which your appliances are rated. If your Victron inverter is set to 50Hz, it should be used with devices that are also rated for 50Hz. Changing this setting is usually only necessary if you move to a different region with a different power standard or if you import an appliance with different frequency requirements.
Here’s how to adjust the ‘System frequency’ setting:
-
After entering the General settings menu in the VictronConnect app, locate the ‘System frequency’ option.
-
Tap on the drop-down menu where ’50Hz’ is displayed. This will allow you to choose between the available frequency options, being either 50Hz or 60Hz.
-
Select the frequency that corresponds to your local grid or the nominal frequency of your electrical devices.
