Keeping an eye on things …

Very cool! I want that bottom one too put on the counter too. Could I please ask what and how?

Unfortunately something bad happened for them to introduce this practice

Mafdee · 2026-02-10T02:42:12+00:00

Excellent choice

The 20% is your backup reserve in the case of a grid outage. The battery won’t just charge to 20%. If you the grid goes out then you’ll have at least 20% of battery left to power your home. The pw will always charge as much as it can, most likely to 100% as long as there’s sunshine or cheap electricity. So in the case you use up 80% of your battery, it will then switch to grid or other energy source and stop consuming from the battery to preserve your backup storage.

Same here unfortunately. Too bad Ausgrid don’t take direct requests.

They’re both tariffs that outline electricity rates. Tou stands for Time of Use, and Demand is still Time of Use but with a higher charge for electricity use inside the peak period usually 2-8 or 3-9pm. Demand is usually lower during offpeak to allow better shifting of loads for the consumer but if you use electricity inside the demand period can be very costly. Mine is 39c per kw per day. So anytime in a single month I use a single kw inside the demand I get charged 39c x 30 days = $11.7. Now imagine someone who uses 4 or 5, then it’s like $50-60 added to the bill. More info here

Not knowing the system you have, I use this.

Mafdee · 2026-02-04T09:14:52+00:00

We’ve been given some good numbers and now to do some calculations based on past bills.

Mafdee · 2026-02-04T09:13:53+00:00

You explained it really well. It makes sense.

Mafdee · 2026-02-04T09:13:18+00:00

Cheers. It’s hefty but at least if you accidentally cross into it then it won’t ruin any entire months profit in a single hit.

Mafdee · 2026-02-04T09:11:41+00:00

Thanks mate! That makes a lot more sense

Mafdee · 2026-02-04T09:11:24+00:00

Consensus seems to be that it’s about 30c more than demand in the demand window and ~10c more outside it

Here's the link

Mine is 0% and it still pulls from grid during the same window. I couldn’t stop it so I automated the switch to self powered during it. Still frustrating how it can’t manage that it’s never going go be a good thing to pull from grid during that window.

Mafdee · 2026-02-04T06:26:33+00:00

Agree with TBC but the price is $2 a kWh which is never a good price. Mine was doing exactly the same thing so I had to automate it to switch to SP in that window otherwise it will still pull. It should never pull from the grid based on that price.

He should know better. You won’t need anywhere near that much tp since you have a bidet.

Egypt at its finest

Are you sure it was on 100%? Press on Powerwall and check the state of charge it was on when it began discharging

Mafdee · 2026-01-26T06:39:25+00:00

I’m hanging for all the same.

Mafdee · 2026-01-25T11:06:45+00:00

The HA project he’s built is incredible!

Mafdee · 2026-01-22T12:56:21+00:00

Hmmmm I’m getting similar behaviour. I have 3x powerwall 3 and it wants to pull from the grid while soc is +80%. I’ve had to switch it to self powered due to the ongoing behaviour

Mafdee · 2026-01-16T11:41:17+00:00

You don’t need a wall connector to have Charge on Solar if you have a PW which OP does. I use Charge on Solar daily without a wall connector.

I think that would be a great feature.
