Tesla won't free up use of its batteries, leaving owners unable to
reap full benefits
...

Tesla is required in many US states to enable so-called
interoperability of batteries. However, the company disables that
capability in its main storage product - the $15,000 Powerwall 2
battery - it sells to Australians, industry participants say.
They say federal and state governments should impose US mandates on
Tesla and other battery suppliers according to an international
standard - IEEE1547-2018 Clause 10 - to maximise future benefits to
consumers and the grid, and firms restricting utility should be
excluded from rebates, such as New South Wales' subsidy program of as
much as $2,400 a battery.
"Batteries that do not offer their full performance via an open standards-based, non-cloud control port are too easily locked into a
particular business model to the detriment of their owners," said Dean Spaccavento, the chief executive of Reposit Power.
