It states that Australia power standards are 230 volts, +10%, -6%.
Apparently it changed a while ago from 240v to 230v.

Just spoke with my brother about it. He says unfortunately with grid connected
solar you are still affected by the voltage of the grid. In his case, he can
disconnect from the grid and in that case it outputs at 48v, then an
inverter(?) boosts it up to close to 240v (48 x 5). He has measured and it is
usually sits around 235 volts when he does this. But when he is connected to
the grid, he gets wild fluctuations which he says he's proven are caused
entirely by the grid and not his solar set up. His voltages have been between
245 and 267 at times (in Brunswick.)
He says you might be able to make a complaint to the grid authority because
your voltages are outside of Australian Standards, which he says is +/-10%
around 240 volts (so a minimum of 216 volts)

No UPS is going to generate power for you. You’d need a generator for that.
Do United Energy have any sort of service level agreement? Or any agreement on
what the tolerance should be? In the end, it sounds like you need new cabling
to your area and only the supply company can do that. Last time I looked at
this, the guarantees that they provided were very limited. It was almost as
though if anything came out of your power points, you should be giving thanks
to them.
People have been successful in giving the electricity companies a hard time
about quality of supply but it’s a hard road. I know of one in Queensland where
they eventually gave in and power conditioned his whole house just to shut him
up. (Mind you, he’s also been banned from the High Court as a serial pest so
you can imagine the lengths that he was prepared to go to).
Is there anything else in your street that could claim a strong need for better
quality supply? For example, anyone on sensitive medical equipment?
A lot of computing equipment used to be rated as 220V +5% -10%. Those devices
should be fine. But those that are 240V nominal might be a problem. I recall
that Western Australian areas with 250V nominal used to be a real hassle for
some equipment.
In desperation, I’d suggest trying:
1. Finding computing equipment that’s designed for 220V rather than 240V.
(Some power supplies have switches on them, and you might be able to order a
different power adapter for a notebook)
2. Get a big transformer (eg. 2KVA) wound for something like 215V in and
240V out, then use a UPS.

Subject: UPS
I am suffering major degradation of power supply over these winter months. The
voltage drops to 204V during peak load periods and sits any where between 215
to 230 during the day.
Contacted United Energy several times - they are playing tricks like not
turning up when the problems are manifested and measuring the power at
midnight saying it's OK. Talk to the technicians they say that because I
live at the end of the street there are several new units tough luck
charlie.
What I am thinking is to get a decent UPS that would regulate the supply, but I
am not sure that they would work over a number of hours. It would need to
support 6 PCs. Does anyone have any recommendations ?
