I put them off due to the $660 cost and asked about the cheaper option of 1 phase. I have since contributed 300 odd kw hr to the grid but the last bill was estimated at a reading 6 mths ago charging me 48 dollar when my meter was winding back. When they changed my brothers meter they ignored the 200 kwh he had contributed to the grid. If we stole power of synergy we would be in court.
THANKS FOR THE FORUM TONYP

Hi Tony ,
Welcome to the forum ,
Yeah your right stealing power is a criminal offense , but I really doubt Synergy are connecting you up with a new meter and purposely stealing your contribution.
I am also connected with Synergy and called them up before my system was installed and they suggested if I wanted to be credited with everything I export to grid it would only be possible with the new meter , the old meters where never intended to read backward or count what is going backwards.
Also you need to realize that not all power your PV system makes is recorded even with a new meter , only power in excess of what you are consuming is exported to the gird , EG if you are using 1KW in your house and the PV is making 1KW , there is no import or export recorded on the meter , without a new meter there is really no way of knowing how much you consumed and made during the period without the new meter.
The 300kw displayed on your inverter gives no indication of what was exported to the grid , being summer they could safely assume your usage has risen as 99% of peoples usage does during summer and that the 300kw was absorbed in your usage.
It would take a complete energy audit to calculate what happened with this 300KW , costing far more than $48 I can assure you
While its great making this contribution in the scheme of synergy customer 300kw is quite trivial , I was speaking to a customer of mine last Thursday who's power usage is 90kwh per day $1051.75 for 65 days , up from his last bill $653.75 , the increase due to air conditioning and pool. , So basically everyone last bill in Perth on a standard basis is higher than the previous bill , in your case what they are using as a reference is when most peoples bills are at their lowest.
