2 inverters and g83

[dansk]

Hi, small system using two inverters, what do I put on the g83, do I just list two inverters and two serial numbers?

Also do I run them both through the same meter? Like from both inverters, through 2ac iso, then both wires through same meter then 2ac iso again and into 2 mcb.

Yes, just list the two inverters.

You can't take them both into the meter and split them out again (unles you've got a very special meter!)


Two inverters, Two AC Isolators, to a dedicated CU (2 MCB, RCD if needed, optional Master Mains switch) to a single Generation Meter (remember to wire it the correct way - Supply = Inverter(s) Load = incoming) to a single Lockable in the Off Position Only, two pole Isolator, to Incoming Supply.

There is some discussion that if the main switch in the dedicated CU is two pole and lockable with a padlock, not some proprietory device, then that meets the requirments, so no additional Isolator needed.

Cheers - i understand, ive done plenty of single inverter systems, but not duel, and ive always put the meter between the MCB and the Inverter, and never between the MCB and incoming supply, but i will on this job.

Thanks about the G83, i thought that was the case but you have re-assured me thats how to do it.

Can I add expand on this one please.

I have 2 installs lined up that are expansions to systems, can I connect to the existing generation meter thats on the existing system (and FIT contract) or do I need to add a new Generation Meter?

Both original Installations were installed within the last year, In the SSE FIT customer contract it has a clause saying upgrading the system within 1 year is possible.

Hi I am sorry once again to hijack this thread . I am installing a dual inverter pv installation . the thing is one is 3 phase one is 1phase . The MCS company have registered 3 single meters . unfortunately the electrician that started the job was intending to piggy back into one of the meters for the single phase inverter . My concern if you will be gentle with me is the neutrals and switching . If it were 1 inverter on its own then i would only use one AC isolator between the meter and the CU . Because there is 2 inverters doing this for both would in my eyes cause a problem caus if you isolate one inverter there will still be a live feed through to the 2nd . My proposed way round this is to put 2 more isolators between inverters and supply side of meter . this theoretically allow one machine to be COMPLETELY isolated . double pole for 1 phase and 4 pole for 3 phase . Can any one see any other issues as i need to complete this install for them tomorrow . cheers guys
