Hello We understand that our multiplus ii needs to be configured to function as a microgrid for a grid tied Fronius Primo. We also understand that an mk3usb is required to allow a laptop to communicate with the multiplus. I've just been watching a YouTube tutorial to prepare for this and heard the person say that I am not granted access to the settings unless I am a qualified installer or have done Victron training. Is this an accurate appraisal of circumstances? Thank you.
