Can you tell us about it first, so I know how you're going to charge the battery under what circumstances... For instance, I would suspect per half hour depending on the price of the input at that time, charging at the lowest prices during the day and making sure there is enough charge in battery for the peak time. That means charging perhaps many times during the day to get the absolute lowest tariffs. Here are my tariffs for today for example... bold are possible charge times... **00:00 - 00:30 14.43p/kWh** 00:30 - 01:00 16.51p/kWh **01:00 - 01:30 15.54p/kWh 01:30 - 02:00 14.68p/kWh 02:00 - 02:30 15.48p/kWh 02:30 - 03:00 14.51p/kWh 03:00 - 03:30 15.56p/kWh 03:30 - 04:00 14.74p/kWh 04:00 - 04:30 15.56p/kWh 04:30 - 05:00 14.7p/kWh 05:00 - 05:30 15.54p/kWh 05:30 - 06:00 15.75p/kWh** 06:00 - 06:30 17.81p/kWh 06:30 - 07:00 21.42p/kWh 07:00 - 07:30 22.34p/kWh 07:30 - 08:00 24.7p/kWh 08:00 - 08:30 19.32p/kWh 08:30 - 09:00 22.68p/kWh 09:00 - 09:30 21.44p/kWh 09:30 - 10:00 20.6p/kWh 10:00 - 10:30 20.16p/kWh 10:30 - 11:00 19.36p/kWh 11:00 - 11:30 18.04p/kWh 11:30 - 12:00 18.14p/kWh 12:00 - 12:30 19.43p/kWh 12:30 - 13:00 17.66p/kWh 13:00 - 13:30 19.38p/kWh 13:30 - 14:00 18.06p/kWh 14:00 - 14:30 20.83p/kWh 14:30 - 15:00 20.29p/kWh 15:00 - 15:30 19.3p/kWh 15:30 - 16:00 22.49p/kWh 16:00 - 16:30 35.55p/kWh 16:30 - 17:00 39.9p/kWh 17:00 - 17:30 38.6p/kWh 17:30 - 18:00 39.38p/kWh 18:00 - 18:30 38.56p/kWh 18:30 - 19:00 35.87p/kWh 19:00 - 19:30 22.05p/kWh 19:30 - 20:00 21.04p/kWh 20:00 - 20:30 21.17p/kWh 20:30 - 21:00 18.92p/kWh 21:00 - 21:30 18.82p/kWh 21:30 - 22:00 17.7p/kWh **22:00 - 22:30 16.8p/kWh 22:30 - 23:00 14.76p/kWh**

Today because my battery level is so low, I topped up the battery during this period too... 12:30 - 13:00 17.66p/kWh 13:00 - 13:30 19.38p/kWh 13:30 - 14:00 18.06p/kWh

@"Gazzagreen"#p635 Sure, no problem. Basically, during your specified window here: [URL=https://i.imgur.com/JIIZARb.png][IMG]https://i.imgur.com/JIIZARbh.png[/IMG][/URL] Wonder Watt will based on those settings determine and pre-select the cheapest number of half hour slots for the next day when they become available. That will then look something like this - the reason they're greyed out is because the time is in the past: [URL=https://i.imgur.com/U5CcBmX.png][IMG]https://i.imgur.com/U5CcBmXh.png[/IMG][/URL] Which means 4 separate charge slots would be sent to the inverter prior to the start time of each of those 4 contiguous blocks. You can also easily select and deselect slots and Save your changes for scheduling. Does that make sense?

@"Gazzagreen"#p636 Yeah, I still have the option to add slots too by simply selecting them and Saving. See: [URL=https://i.imgur.com/SLUlTIR.png][IMG]https://i.imgur.com/SLUlTIRh.png[/IMG][/URL]

Is there anyway we can set the max charging percentage for the Agile Tariff charging settings?

@"TomKatt1993"#p672 Not currently, I guess it would be max percentage configured against the each Charge Window? Your target for 00:00-06:00 might be 80%, but for 11:00-15:30 100%?

Agile Octopus integration

Giles

A recurring problem I’ve seen is charge-slots being missed when the SoC of my battery is greater than 80% (is this % user configurable?), then my car charger kicks in & dumps the contents of my house battery into the car, instead of continuing to use subsequent cheap half-hour slots. This isn’t strictly a WW issue, but the hold charge idea suggested above, would provide a neat work around. At present I can temporarily increase the min. SoC in my Growatt portal to 100%, to stop any discharge while the car charges, but this is hardly a practical solution going forward, as I always forget to reset the min. SoC to 10% after, so we can use the battery again!

I assume other Agile users with both house & car batteries to charge must have come across this, when the car takes longer to charge than the house battery and WW has selected non-continuous slots?

admin

Giles Yeah - thanks for this, we are working on this hold-charge solution for gapped slots within your Agile charge window. Might be a week or so away, tops.

KevinD

Just to report a successful scheduled export this afternoon after the failure a couple of days ago. Only a test slot of five minutes but all went perfectly 👍

admin

Thanks for that @KevinD !

I have just noticed that the house was still being supplied by the grid, " ECO " not having been re enabled at the end of the discharge period. I had to go into inverter settings to enable it.

aniseedvan

KevinD I noticed my inverter also had eco turned off this afternoon. Note I didn’t have any force export scheduled slots today (but did try and use it unsuccessfully yesterday as others have posted), after my missed half an hour charge slot this morning I used the quick settings in the giv app to top up the battery for 30 mins and I think all day the usage has been just solar & grid (I’ve been out all day so not watched it a great day).

admin

We fixed an issue with that earlier but will look into more detail and get a fix out tomorrow morning if needs be.

Basically, it might be fixed with our latest release we deployed earlier this afternoon. But might have been after your schedules finished.

With those multiple releases a day, we need to start adding timestamps on those release notes!

Thanks again! You’ve all helped out a ton. 👊

Gazzagreen

I'll do another test tomorrow morning and report on the Eco setting. I know it didn't switch on after the test earlier this morning.

admin

Gazzagreen Much obliged Gazza, should be good now, famous last words!

Gazzagreen

admin LOL. I'm sure it will be good.

BTW, what do you feel about the Intelligent Flux tariff? I believe this export is controlled by Octopus?

admin

Gazzagreen I think all it can do is send you lucrative export slots, which might be ad-hoc.

We’ll be looking at OI in a bit more detail, few users are helping us out there too.

Gazzagreen

And last message for the night....

Do version 1 inverters and version 3 inverters show the same faults when things go wrong, could this be a reason? I ask because i am planning on upgrading my version 1 in April.

admin

Gazzagreen There’s definitely differences in the way they behave and how defaults are set up. But we’re aiming for it to sensibly work on all, without too many specifics going on, like if model a do b, if model c do d….because it just gets too messy and prone to error.

Gazzagreen

My agile charging, 4 different charge slots of varying length all worked correctly to day.

However, I did another export test. ECO came on at the end which is good, but the battery didn't export at all in the 6 minutes I set.

admin

Gazzagreen Right, so all looks OK, and instructions correctly sent.

I have a sneaky suspicion that setting a 5 min export is basically not long enough for the inverter to start dumping at full rate. There might be some protection built in, in a similar way that once the battery nears 100%, the charge rate throttles down.

Also, you may not see stuff on the app/mobile due to the 5 min refresh, which could be another factor.

You could prove/disprove this by doing two experiments.

Set an export via the Giv app/portal for a similar amount of time, 5 or 6 mins
Set a longer export, perhaps 20 mins or so in WW

Gazzagreen

Will do later this afternoon.

Gazzagreen

OK sent a private about this. I tried exporting for 20 minutes but the export did not start. The Eco switch in my inverter settings remained in the on position

admin

Gazzagreen Yeah, looks like you set export SOC requirement for export/discharge slot to be 90% but:

It should say this in your WW activity log too.

Gazzagreen

Trying again LOL
