Agile slot - how to always charge regardless of battery SOC

johalareewi

Is it possible to have selected Agile slots always charge regardless of battery SOC?
During the day whene there is lots of solar and very cheap Agile slots I want to go on-grid and not use the battery and was hoping that auto selected slots would send an AC charge command to the inverter which would then just use solar+grid.
However, it seems that if the battery SOC is 100% the AC charge command is skipped.
I vaguely remember a thread here that talked about allowing the slot to charge even if the SOC is 100% but can't seem to find it.
Is this possible?

johalareewi Yeah we can introduce an Advanced setting for this to allow users to choose that option.

I'm away for a few days, but we'll get this implemented before end of next week.

Using ‘Quick Schedule - Charge’ on the ‘Home’ tab for 120 minutes your battery charges to 100% then house runs off grid/solar. Did for me today, anyway.

Cool. Just to be clear, this will only happen if the Agile window's "SOC Less Than" setting is 100% AND the battery SOC is 100%.

I have Agile windows with an "SOC Less Than" value which will still need to work.

It is only Agile windows where the "SOC Less Than value is 100%" and the battery SOC is 100% that I would like to be able to choose to always charge.

I did try to enter the SOC Less Than value as 101% but the system wouldn't allow this.

Did thia happen?

Would have been handy to have it this morning. I manually selected some Agile slots because the EV was going to use them to charge up and I wanted to make sure the GE battery was topped up ready for the 4pm peak (and not emptied into the EV). However, the GE Battery SOC was 100% so the slot got skipped and so the EV charged up using the GE battery (and solar). 🙁
Luckily, WW checked again in 30 mins and the battery SOC was no longer 100% (it was in the EV!) so WW sent the commands to start AC charging.

johalareewi We're putting an easy fix in for that now, should take 10-15 mins to be deployed.

Allowing Agile Window less than condition to be 101%, which means when you specify that, the charge will never be skipped, allowing you to effectively draw from grid.

Update: This has been rolled out now as part of release 1106.

admin Cheers. Obviously won't work for manually selected slots outside of an agile window but gives me a workaround. WIll be testing it ASAP

Agile prices are such that this should be tested today.
Got an Agile window with 101% SOC test and selected slots.
Battery should be 100% at the time thanks to solar PV.

Looks like it worked.
Although the slot was auto selected because it was less than 0.00p so maybe that is why ot worked?

Update:
Looks like it may have been actioned because it was less than 0.00p because another price plunge slot has been activated even though the battery SOC was 100% and the window SOC test is 60% (so that test should have failed).

admin

johalareewi Yeah fair, what do you think could be done for that? What would be a good solution?

johalareewi

admin What would be a good solution?

I guess an option in the advanced settings?
Don't skip AC Charge when battery SOC is 100% [on/off] (default off)

Or
Skip AC Charge when battery SOC is 100% [on/off] (default on)

Unfortunately, the clouds appeared and the battery SOC hadn't reached 100% when the agile slot went active. Try another day...

johalareewi

Lots of scope to test this tomorrow (Tuesday 24th).
Plenty of low price Agile slots that I have selected in a window with SOC% 101 set.
Battery SOC should hit 100% for at least 2 or 3 of them.
Lets see if the AC Charge command gets issued or if it is skipped.

johalareewi

Finally got to test this today (Test SOC%=101 to force AC charge when battery full).

It doesn't seem to work.
I have an agile window with SOC% test=101 and charge slots selected (13:30 to 15:00)

The AC charge started ok at 13:30 with a re-evaluation in 30 minutes.
At 14:00 the battery SOC was 100% but instead of keeping the charge going, WW did a slot skip.

And WW sent commands to stop charging

So it looks like there is a "skip if battery SOC = 100%" test before the "battery SOC less than the agile window value" test. 🙁

johalareewi Thanks, we’ll squash that one and update the thread here!

johalareewi Fix being rolled out now. Although I think we will follow this up with an Advanced setting next week for Agile 'Skip charge if SOC 100%' toggle, defaulting to on. But will leave the Less than 101% workaround in place as well.

This will also be handy for charge slots that are not in an agile window. 🙂

Looks like the test for battery SOC% < 101 has worked this afternoon.

Agile window has test set at 101%. Battery was at 100%, 1 slot selected at 15:30 and WW fired it off.
