Its going to be a huge issue perhaps. The ability to shut down solar export and the Solar system itself via remote inverter control is already happening in places South Oz? [bigwhistle]
The number of EVs is slow here despite growth rates being pumped as huge [biggrin]
Electric vehicle sales across the country surge with over 45,000 sold in first half of 2023
Its about a million other cars per year[bigwhistle]
Biggest issue for some is 
Solar panels switched off by energy authorities to stabilise South Australian electricity grid - ABC News
And QLD  
"A new rule that will require large numbers of Queensland rooftop solar systems to be fitted with “mid-20th Century” technology has been slammed by industry and peak bodies as outdated, reckless and likely to impose “significant extra costs” on consumers and installers.Energy Queensland 
has revealed that from February 6, 2023, new and replacement rooftop solar and battery storage systems of 10kW and over will be fitted with a generation signalling device that will allow the state’s network operators to switch these PV systems off, remotely, if needed.
The generation signalling device, also referred to as “ripple control,” is Energy Queensland’s answer to the increasingly pressing problem of large amounts of daytime solar exports sending operational demand so low as to threaten system security."

"
The Australian Energy Market Operator (AEMO) recommended the measure as a means of mitigating the threat to grid security posed by the rapid growth of rooftop solar, which has led to days of very low demand."
My work Victron Inverter Chargers are no longer Complient I heard yesterday.[biggrin] They are certified so they stay put. I was thinking of moving them to my home. They cannot be controlled by others happily. Not that I export except for a bit on Sunday perhaps.
