The Victron Multigrid is very similar to the Multiplus. There are a few key differences that are required in some grid connected markets, and these additional features can lead to some confusion and troubles during installation, commissioning and operation.

This FAQ seeks to address the most common issues that arise, explain why they do, and how to correct them.

The first step is always to be sure that all Victron equipment is running the latest firmware versions. These are available from https://professional.victronenergy.com

The following information is all subject to local codes, standards, regulations and guidelines. These vary widely and it is not possible for Victron to give specific advice for your area. Your local Victron Distributor may have additional, locally specific information. IT IS THE **RESPONSIBILITY OF THE INSTALLER** to make sure that all their work is performed in compliance with their specific regional responsibilities.

This information refers to circuits that contain potentially fatal voltages and are intended for use by suitably qualified and trained professionals. Appropriate safety procedures should be followed at all times. 
If in doubt, do not proceed and seek the support of another technician.
