Why Choose Jousto for Battery Storage in South Australia?
Integrated Solar + Battery Inverter
Powerwall 3 is unique in including a built-in solar inverter — eliminating the need for a separate solar inverter. For new solar + battery installs in SA, this simplifies the system and reduces component count.
Tesla Energy Plan VPP
Powerwall owners in SA can join the Tesla Energy Plan, an approved SA REPS VPP program earning the $2,050 incentive. The plan also offers competitive export rates when your battery is full.
