As NSW has Gross Metering PV FIT, you are metered for import and export power at the same time, its technically possible to rig up a 230ac to 250-350dc (MPPT Inverter Range) feed into Inverter input.
example you pay 22c for kw/hr from your power point and you get 66kw/hr for what you export, its not too hard to rig up such a set up for $200-300, im suprised this scam has not come to light sooner?
