Winter is maybe not the best time to try, but there is no contact so if you try it and don't like it you can get out with no issues.Interesting thread, I’ve learned a lot looking through some of the previous posts. I’m in VIC, 16kW solar system with Powerwall2 and a Model Y. Currently on a flat rate plan which equates to 18c/kWh. I’m at a crossroads now, looking at all these plans and now Amber. Right now, with winter looming in VIC my flat rate is good and bad, most days I can get all most of the PW2 charged, but there are days when I can’t and we need to run the heaters more. In that case, the 18c/kWh isn’t bad, but at this rate the ROI on the PW2 is extremely long.
I don’t need to charge the car often and have a static load of around 500W (fridges, cameras, switches, APs, etc).
Based on that, do I try this Amber Smart Shift out? Or perhaps look to some time of EV plan with a lower overnight rate of 8c/kWh and try to sneakily charge my PW2 instead of the car?
I was on a 10c tariff overnight which I used to use to top my battery up so never paid more than 10c, I'm MUCH better off on Amber. Each state is different though so worth while doing some research and checking the prices over a few days to see if it works for you.
From what I hear VIC gets more negative tariffs in summer which is great for charging vehicles and batteries. You've also got the arbitrage opportunities buying low during the day and selling at night which is where I make most of my profits.
I've got a little video I put together to show how it all works, it's posted earlier in this thread if you haven't seen it.
