The VictronConnect app can be used for programming the MPPT.
For programming the Multiplus use either of the options below, detailed instructions in the links.
- A smartphone using the VictronConnect app with a Mk3 USB interface between the phone and the Multiplus.
- A PC/laptop using the VE Configure program with a Mk3 USB interface between the PC/laptop and the Multiplus. I am not sure if VictronConnect on a PC/laptop can work like this or not.
- A PC/laptop using the VE Configure program through a GX device if you have one connected to the Multiplus and the internet. This is VE Remote Configure.
