Dynamic Pricing Tariffs

Texas has learnt their lesson. Since then they have been on a race installing wind, PV and battery at break-neck speeds and they are now more renewable than California. Who'd have thought that about the oil red neck state?

Yes but since battery storage is quite expensive, last I checked it was about €1k/kWh, you would have a long payback period

Yeah that's what I'm not picturing right now, we'll need to poll some sort off api to get those sweet hours to hammer the EV and batteries for max gains. And if this has to come from the suppliers, good luck to us all with those chumps.

Boxes don't pay for themselves (read: unkel says they are a waste of money). But you can get a JK BMS for about €60 so that means a 16kWh battery pack fully made up for under a grand. Amazing stuff and as I showed, payback time 15 months currently on Pinergy if you can fully cycle it once a day. That is a return on investment of 80%. Can't think of anything else with such an incredible, risk free and tax free return 😁

Clutching at straws much? 😂 If you are smart, you have the battery and inverter in a room that needs heating and is insulated. All the waste heat from inverter losses and batteries is then useful instead of wasted. That's what I have, it is heating my garden room. Then it matters nothing whether you have a box or not.

You do not need compression either. It is useless on most batteries except the weaker EVE type cells and might increase their longevity from 40 years to 50 years. Do you really need that 😂 Complete waste of time and money to compress them…

To the letter of the logic it should cover export because if you export between 5-7pm it's worth more than exporting at 1pm

Standing charges should also be lower for exporters using the same logic but given the introduction of FIT was akin to pulling teeth it's unlikely to ever happen

So what of what I was saying was "absolutely" not true? Of course the weak EVE type cells swell a little and have a shorter lifetime if you don't compress them for the first few cycles. But in real terms it means they last a bit less, but less than what? Even without compression they last way longer than you will actually use them in real life. A bit like a washing machine. It might technically last 30 years, but you will likely replace it far earlier with a better more economical one that uses more modern techniques.

My point is: do not spend a cent on anything other than batteries, it does not add anything to payback time. But your moneys, if you want to spend more to fancy it up, by all means do so. But knowing it is just decorations. Let's face it: the only reason we buy batteries in the first place is for them to make us money. Use them to the max.

Mine ran out over a year ago but continued on the plan on a month to month basis which opens up the opportunity to jump to better plan elsewhere if it comes around. But as is now have no intention of leaving pinergy

What would you call a "powerful inverter"?
I have a 10kW Three Phase Solis hybrid inverter with a 7.2kW array and a 5kW Weco battery, I've generated 10.2kWh so far today and exported 7.65kWh of it.
Would more batteries make sense? Im with energia on ev tariff and charge the weco overnight. (however its fully discharged pretty quickly in the morning!)

Does more batteries make sense in my case? Also, while generating during the day, should I charge the battery rather than export? Seems like that would be better financially?

Just on this equation for anyone with a standard 12kva connection and the limited ev windows I'm guessing the max battery recommended should be 40kWh. 12kw * 3 hrs.

That's not taking into account EV charging, heat pumps, house load etc or speed of charge of inverter.

Agree with @slave1 - panels, panels, panels everywhere first, provided you can get that done for reasonable money. Battery prices are coming down and it is fairly easy to add more batteries to an existing setup later
