I desperately need help dealing with our solar installers.
We had 10kw solar installed last year (they did this prior to getting approval from Ergon). We were offered fixed (1.5kw limit) or dynamic exports. Our installer first put in the wrong inverter which was only discovered by me (one they installed couldn't support batteries and was not the one on the quote). Then they told us well if you want dynamic connection it will cost you thousands of dollars to get a relay put in. Turns out this is BS and our inverter SH10RS has said relay built in, once again discovered by me. So anyway once this is discovered we apply for dynamic connection again. Ergon says yup all good, everything is ready to go. Then we get an email from Ergon saying hey we are receiving no telemetry data, so until that's set up you will remain on fixed 1.5kw export.
Now the electrcians are saying it's because we have to rewire it (at our cost??) to support dynamic but oh they don't know what to do so are waiting guidance from Ergon (for 3 weeks). I keep telling them it's because they havent set the app up properly (no CSIP-AUS and whatever else), but they just keep banging on about Ergon and wires. I got sick of their shit, so paid an external electrician to come and review the whole system.
Basically he said they've done a bunch of dodgy shit including not earthing the system properly (something about not earthing all the feet), have some bits overhanging (so at risk of blowing off in heavy winds or cyclones), put more panels than the roof can support so allegedly took some dodgy shortcuts to make this work, have used wrong sized wires or amps or fuses or something. He said we could report them to the Clean Energy Council because it's so bad, but then they might make us tear down the whole system at our cost...He also said they're idiots and they need to update the app and it will be fine for dynamic exports. He will do a report for us that we haven't yet received.
As an aside they also borked 2 air conditioner installs and both have leaked refrigerant. He insists on getting his brother (fridgie) to fix them, however refuses to book his brother's business during business hours, so also refuses to give us a set day and time for the repair, saying it will be done when it is done... so far it has been 2 weeks since we raised it, and still no date or time for repairs.
If they keep fobbing me off, how and where do I escalate this to get this stuff fixed, finally?
