> Australia was only recently allowed to include batteries on solar. Source? Tesla Powerwall was introduced into the Australian market in 2015. From what I understand, other residential systems existed before that, but they were uncommon. In 2019, they significantly tightened the safety standards, but the impact on people running approved off-the-shelf systems (such as Tesla's) is modest (tighter rules on installation locations may cause issues for some people, especially smaller properties–although those rules only apply to new installs, existing installs are grandfathered), most of the added burden is on those rare people who have bespoke systems.
