I've agreed to buy a used 4KW solar system with the intention of(I just made a phone call looking for a local Sparky [Seymour/Kilmore]
installing it myself on a frame built at ground-level (there are
no nearby trees or structures, so shadow shouldn't be a problem).
It's coming with an inverter that's still a current model, which
I'll have to get an electrician to hook up at the meter panel.
I notice that there are a lot of regulations around solar
installations:

Does anyone know if it will be easy to get an electrician to just
hook the inverter up to the mains without them demanding that the
solar panel installation is inspected first?
to supply and install a Battery to connect to my (already installed)
4.5kW solar system)
Quite possibly you would be able to get the electrican to certify the
panel installation at the same time as they did the hook-up, wouldn't
you??
Give your friendly neighbour Sparky a ring, I guess.
The one you are gunna get to certify the inverter or, maybe
better yet, another independant one!

Hmm, if it comes to that I guess. I'd prefer ganeral advice though
in case I end up using a different one by the time I've got
everything set up. I'm in the country so there isn't a "neighbour"
sparky as such. It's a matter of who'se willing to make the drive,
and ideally for a fee that's not completely disproportionate to the
$500 I'm paying for the solar system, although I'm braced for
disappointment on that front.

Yeah I guess if I ring around enough I can work out the general
advice for myself eventually. The inverter is _already_ certified
though, with an AS / NZS 4777.2: 2020 certificate of conformity
downloadable from the manufacturer's website. As it should be,
given that distributors are still selling the model. Getting one
certified by a lab would surely cost a fortune, which is where I
wonder about how much of a dealbreaker it might be if something
else turns out to need certification as well.
Lack of AS / NZS 4777 certification is apparantly why "plug-in"
type solar inverters aren't allowed to be used in Australia: https://www.energymatters.com.au/renewable-news/plug-in-grid-connectsolar-inverters/

Solar panel strings use high voltage DC wiring. You should get it
inspected for safety in any case. High voltage DC is very much more dangerous than ordinary mains wiring, because DC arcs don't quench easily.
It sounds like you're mounting the panels at ground level where children might have access. I suggest that failing to fence the panels securely
would be a very bad idea.
