I too am a victim of the 5k rule, and i get a miserly 11 cents for what i give back. If it is not a air-con day, i use about 17kwh a day. 35kwh if its hot, and every air-con is on but on a good summer day i can make 20kwh by midday and 12 in the afternoon, I live in a suburb with street trees, so one side of the house is shaded in the afternoon. But i could send 15kwh back on a good day, and its no like i dont get a bill, shore the kwh charges are tiny, but the supply charge and the metering charge and all the other crap charges, are way more than the power ever is.
So my inverter went bang. and a new one was provided but it more modern and more powerful than the old unit. (Read the model i have is no longer compliant with the current standard so even though i can buy one for $199, i cant, use it, but its exactly the same as the dead one. IT HAS TO BE COMPLIANT AT TIME OF INSTALLATION).
So have given up on the guys from Origin, my most useful and helpful energy supplier, the company that In fact when the inverter was first setup there installer screwed up and i was exporting all my excess power.
Not my fault, but i did get a bill for the excess, and a charge for exceeding the aloud grid export amount.
So if your like me consume it all your self, we had the booster for hot water heater, connected to the inverter, they charge me 13 cent for the off peak electricity that i use , but give me 11 cents.
So the local sparkie dropped in today to leave his fathers seagull outboard for me to fix. and i was having a winge about it all. And told me he had done a job earlier this year and he guy had a bunch of panels he had bought of gumbay or Etree and and a second hand 5kw inverter, just plugged into a power point in the garage. DIY solar, Some homes in QLD have smart meters installed, but there not configured, for implementation later. mine wnt in 10 years ago. So i wonder how many of these setups there are around the country, and how much power they are producing and sending to the grid? And what chaos and mayhem they are creating.
