" Thinking about buying a Tesla battery through AGL?
Little bit of smoke and mirrors how they sell you the concept.
I was all for it as it was going to be finaced interest free for five years at $221.00 per month.
I was told the power collected in the battery together with my solar panels supplying house power during the day would mean I could expect to be in credit monthly. Sounds good?
Now here’s what they don’t tell you
The battery and solar panels supply power to your house(but not to your electric hot water system which is on a seperate meter.
So last months bill. $221.00 for battery and $153.00 for grid supplied power to our hot water system.
caveat Emptor!!
A bit dishonest really. AGL are happy to sell you the battery, they do however still want to derive an income from your power usage. The net result is I am exporting lots of kws to the grid for 15c per kw at the moment, but having to buy my power back for my hot water system at twice the price I am selling it for.

Saitch - is there a reason you can’t power your hot water from the solar during the day?
That would seem the obvious solution and save you a heap of $$$

Edit: sorry - just RE-read your post and it’s not you that had the issue.

Funny that you mentioned that!

I have programmed our h/w to power off the solar from 0930 to 1130. It's a large system and we have had no issues over the 18 months we have had the solar installed.
I just did a little test and with the h/w, dishwasher and electric jug on, we're only using 5.8kW, so still exporting 3+ kW to grid.

And you will probably struggle, they keep going up in price. We mainly only do the Tesla Powerwall, it's the best we have found, but once our current stock runs out, the price is going up to around $19k installed with the gateway! Our install cost and small profit margin hasn't changed, price increase come from Tesla themselves.

I rencently got a free heat pump hot water service through the government scheme. If you're heating with offpeak hotwater you should be eligible for a free "on peak" heat pump HWS.

Depends what state you are in though

I'm not so sure about this, my Tesla Powerwall certainly discharges when the electric hot water system is in use. We have the EHWS as well as induction cooking and a fully charged powerwall will go down about 70% after dinner and the round of showers.

We only had it installed in March so missed the peak summer months, but even through the dreary winter our bill was about $50 a month, most of that is in the $1.53 a day supply charge.

Interestingly, my son installed a battery in his house only a fortnight ago. One of the more interesting results of this is now his whole family follows and is interested in where their power is used, and is minimising grid power as far as possible - he tells me that they have used virtually no grid power since the battery was installed, and have fed power into the grid on most days.

(For interest, I have been entirely off grid for almost thirty years.)
