Hello all
I am new to this community and to Victron. I have a project to build a new electricity panel in my home and i am posting this as a sanity check. Is what I am proposing viable? The panel will have two distinct power suppliers - one is the grid supply and the other the supply from the Multiplus II inverter (AC OUT 1).
Grid power distribution
Power enters the panel from the main incomer and lands on the first distributor block (via breakers, Surge Protectors, etc) - call this Bus A. From there it supplies a number of circuits and the AC IN of the inverter. Circuits powered by Bus A go dark during an outage.
Inverter power distribution
In addition a cable leaves the AC OUT 1 of the inverter and arrives at a different distributor block (via isolator, MCB, etc) - call this bus B. The power on that cable is either from the battery or from the grid (when the inverter is configured to pass through power from AC IN to AC OUT 1). Circuits powered by Bus B are backed up and continue to receive power during an outage.
Bypass switch
A bypass switch in the panel allows the power feed to the inverter distributor block (bus B) to be either fed from AC OUT 1 or from Bus A. This is accomplished via a I-0-II switch in the panel.
Switchable circuits
Each circuit has an RCBO which takes input from either Bus A or from Bus B. A number of circuits are switchable between the two. The RCBOs for these circuits take their input from a I-0-II switch which in turn takes its inputs from the output of either Bus A or Bus B.
Note that in all cases where circuits are being switched, both the live and neutral wires are switched. Permanently connected (either to Bus A or to Bus B) circuits have fixed connection to the corresponding Neutral Bar.
Is this a well trodden path? When i search for split bus panels, I only come up with references to an old US design for electrical panels. Just want to make sure I am not hallucinating when i assume this is a viable idea.
Thanks in advance
