Obfuscation...
Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
It's just examples of planning issues and differences between states.
But with batteries government's are looking at using them to stabilize the grid which has been talked about same as grid infrastructure.
Im sure SA will make it mandatory for all homes to be grid connected in tge city soon enough to make use of this new tech.
You're just being argumentative so I'll stop responding to your posts here from now.
My last house was 2850w system (peak generation I saw was 3100). And this house I might go a bit smaller as it runs gas hot water.Out of curiosity, what size solar systems are commonly installed in Aussie? Here in NZ I think a 5kw system is a decent size.
Here in ACT/NSW land you know the actual part of the country that matters the most
Hahahaha.
That‘s not true in most cases. Batteries are not for mains backup, they are for dark cloudy days when your solar panels aren’t generating enough for your needs...No the batteries aren't fed back into the grid.....They are a back up for power....If a solar system is connected to the property (and it's not mandatory for them to be into the system), that is fed into the battery pack

I’ve been told in no uncertain terms that a grid connected solar + battery system will go dark if the mains power goes out. You’ll have no lights or telly just like the rest of the area should power go out. It was rationalised as a safety thing as they don’t want such solar systems feeding power back into the main lines at a time when maintenance may be occuring.
In my view, it would be rather simple for the home inverter to have a mains isolation mechanism to stop and feed in when mains drops. And some logic to match the home‘s 240v frequency to the mains frequency when it comes back... None of this is rocket science yet the juice distributors and retailers take the dumb approach because “grid-connected solar power systems must by law shut down if the grid loses power“. See here.
Seems one approach is to wire some loads to the battery via a second isolated system (second inverter?)... In essence it’s like having two systems within the home, the mains connected feed in system and the off grid system for some loads like fridge, etc, with the battery being the common point.. The solar guys I was talking to never explained such as they want the system to be mains connected and they don’t really advocate a battery (at least a couple years ago).
With my last system, I was advised a black out meant my solar system went down too - for the safety of the linesman. (don't want to send power down the lines they are working on.)That‘s not true in most cases.

The Tesla Powerwall 2 has a back-up mode, so it can automatically disconnect from the grid and provide standalone backup power.
What can I say?With my last system, I was advised a black out meant my solar system went down too - for the safety of the linesman. (don't want to send power down the lines they are working on.)
UNLESS I GOT A BATTERY, and then it would run off the battery until power came back up which would save me from the black out.
