The Powerwall 2 is a great product, its attractive for a battery, has a decent amount of storage and a well designed app. Being an AC coupled battery though, it has its pros and cons.
What’s an AC Coupled Battery? – Put simply, it means that the battery charges itself from AC power. It senses surplus solar power and absorbs it and then allows the surplus energy to be exported once the battery is full.
The up side of this is that it can be installed with any solar system. It doesn’t “talk” to your solar system at all so it doesn’t care what solar system you have.
On the down side, it has a 5kW inverter built-in which in Queensland counts towards your total inverter capacity allowance with Ergon and Energex. In Queensland, there is a limit of 10kW of Inverter capacity for single phase properties and because the Powerwall is 5kW, you will then be limited to a 5kW Solar inverter.
