My understanding is that as kWH is a measure of energy (1 kWH equivalent to 3.6 MJ) the system is required to capture and store up to 36 MJ per day. The maximum rate of energy usage is not specified (that is J/s or Watts), so make assumptions based on usage requirements (are you running a LED light or a kettle or a whole house or a whole community?).
EWB Australia acknowledges the traditional custodians of country throughout Australia and recognise their continuing connection to land, waters and community. We pay our respects to them, their cultures and their land; to Elders both past and present; and to emerging leaders. We recognise that the Aboriginal & Torres Strait Islander people never ceded sovereignty of what we call Australia.
