Hi all - my current wiring is like this.

 

All the plant is by the fuseboard.

 

 

Is there any advantage at all to moving the 3 phase meter to be located by the fuseboard and plant ? (like the below)

 

 

E.g. does this help if I start putting PV + batteries in, or exporting to grid, or anything else ? Or does it make no difference at all ?

I assume the PV will connected into the fuseboard (normal situation), therefore there is no benefit to moving the meter.

Are you planning on putting an EV charger in at any point?  You will need to run a cable back to the meter tails for CT clamps. There are other ways of doing this too.  My meter is in a cabinet on our boundary with the main CU in the house and a CU in the garage. Octopus are installing the Zappi and want to run the EV cable direct to where the meter is. I hadn’t planned for this so have had to run a duct behind the wall and up to the cabinet, fortunately I had a spare duct into the cabinet. They also want to install a small CU in the cabinet but there’s no room in it (it’s a 3 phase sized cabinet but we are only single phase) Consequently I have had to install another electrical cabinet beside the main cabinet. The main thing is to plan for this by putting in a spare duct into your cabinet just in case. 
 

The PV panels are being installed on the garage roof and the batteries will be in the garage. I have a spare duct between the garage and the house to connect to the main CU.

Thanks both:

 

1. PV into fuseboard would be easiest, so no benefit.

2. EV charger is actually located right by the cabinet with the head and meter, so moving the meter will be a pain (would need to run another thick armoured cable)

 

Sounds like the best thing to do is keep them as they are ! Thank you !
