And I have just noticed that during this afternoon the Octopus Outgoing export prices are higher than the Octopus Agile import prices so you could import for 15 mins, then export for 15 mins all afternoon and turn a profit. whistlie

Even allowing for charging losses & inverting losses?

Yep, less than 1p to import and more than 3p to export.

I reckon you could easily make some dodgy system using capacitors to import and export every few seconds and not even need any batteries.

OK not quite true as the Octopus Outgoing graph I was looking at does not quite align with the Agile one and the outgoing prices for this afternoon are not on there yet. facepalm

Remember when British Gas did that ďFree SundaysĒ tariff? I thought about convincing a neighbour to get it...

Well the sun has gone in, so switched strategy and currently doing a manual boost on the ImmerSUN pulling 2.7kW to heat up the hot water tank and manual charge on the PowerVault (700W, whoop whoop) to fill those both up before the 4pm peak time.

2.30-3pm at 1p/kWh
3-3.30pm at 0.69p/kWh
3.30-4pm at 1.16p/kWh.

Wonder if we'll get plunge pricing tomorrow...

I did my best to pull the watts during the plunge event last night. 
ImmerSUN, PowerVault, garden room heater, washing machine, dishwasher all on timers and I also put the Tesla on charge too.

Looks like the ImmerSUN didnít cope with the clocks going forwards so fired up an hour late, and the Tesla didnít switch off after the allotted time so kept charging past the plunge window!  Iíd not used the timer in the car before must have set it wrong. Oh well itís all a learning experience.  I should get a few pennies back on my account from that anyways.

Thing is I now have a full battery and instead of the forecast cloud and occasional rain itís currently blazing sunshine out there with a strong cooling wind !  What do I do now?!

Oh the worries of modern life...

Wow, it was sort of true now that the Outgoing figures are out. At 15:00 yesterday you could import at 0.63p and export at 1.38p, in fact for most of the afternoon the export figures are higher than the import.

Got my March figures - 221kWh at 6.61p/kWh average cost, although this doesn't include the plunge event on Sunday 29th!

However, is anyone else having problems with their Agile electricity bills being blank when they're first generated? I've 3 times now had to ask Octopus to go back and re-issue the Agile part of my monthly bill as it only covered the gas element of my supply?

Hi Dan

I think they are definitely having problems.
I haven't had a bill (agile) of any description gas or electric since January !!!  Roll Eyes
Me thinks I need to get in touch with them.

You all seem to be very knowledgeable about how to get the best out of the Agile tariff... I am waiting for my smart meter install before I can switch over to it but I would just like to get some opinions on an addition I am considering for my current PV+battery setup.

I currently have 3.6kw PV on the roof and a lux powertek hybrid inverter and 4.8kwh pylontech batteries.

I have a leased Kia Soul EV and a Zappi charger so I have plenty of opportunity to make good use of Agile but I just feel like I might get caught out when the kids come home from school (assuming they ever go back!) and the mrs puts the electric oven on to cook their tea, and then the microwave and/or the electric hob too.

I'm going to set the lux to charge from the grid prior to the peak time at 16:00 for when it has not charged up enough from the PV during the day but the lux still won't have the bandwidth to cover all of that demand - unless it's a clear sunny day and the battery is full, and even then there may be a gap to fill.

Therefore, I am looking at getting an AC coupled inverter like the Sofar ME3000SP or the Solis 3.0kw 5G RAI that I believe can also be timed to charge from the grid at specified times and either get a new battery or switch one of of my Pylontech's over to that so I will have the combination of the 2 batteries/inverters to help cover the load.

My questions therefore are;
1. Will, as I hope, the AC coupled inverter kick in to discharge it's battery if it sees I am having to go to the grid to satisfy demand? So it will always try to make up the difference when the Lux can't cope?
2. If 1 is true, and I set the Lux to charge from the grid overnight, during a plunge or when topping up prior to the peak time, will the AC coupled inverter think it needs to help out and discharge it's battery into the Lux's? OR is there a way to set the AC coupled inverter to charge at the same time as a priority and ignore any demands?

Hopefully you can see what I'm trying to do and the experts among you can point out where I'm going wrong and hopefully put me right!
