Frequently Asked Questions
Do I need a separate cable to connect this interface to my inverter?
Yes. You will need a standard RJ45 UTP patch cable (sold separately) to connect the RJ45 port on the MK3-USB interface to the VE.Bus socket on your inverter/charger.
Can I use this on Android devices or macOS?
Yes, VictronConnect supports the MK3-USB interface on Windows, macOS, and Android devices (using a USB OTG adapter for Android phones and tablets).
Is the MK3-USB interface required for regular daily monitoring?
