I had an issue last weekend where my regular scheduled evening export finished but my GivEnergy batteries appeared paused (all house power being drawn from grid). On checking my GivEnergy hybrid inverter Eco was disabled, but re-enabling it failed to kick the batteries into life. Restarted the Inverter via the GivEnergy portal twice failed to resolve, and only a physical power off/on of the Inverter and batteries eventually started the batteries providing power to the house. I contacted GivEnergy support on Monday and they said there were no issues with their equipment but it must be an issue with Wonderwatt and the API and suggested I disable the schedule. I didn't believe this but I did disable it last night and ran a manual export which worked fine. Obviously this isn't a full test but wonder if anyone can advise more on this please?
Problems with export via GivEnergy
Thanks for getting back to me. My Watt ID is neat-permission
I have been running my exports via Wonderwatt for several weeks, mostly without issue. The last successful one was last Thursday I think. I should have mentioned that on Friday last, GivEnergy updated my Inverter firmware and battery firmware. Because the batteries were recalibrated overnight on Friday i did stop the nightly Wonderwatt battery charge that night. I had the issue where the batteries were 'paused' on Saturday and Sunday night following the scheduled export. GivEnergy are adamant that there are no issues with the Inverter or batteries and asked me to stop Wonderwatt, so I paused all schedules last night and used the GivEnergy app 'quick settings' to manually export - which worked and the batteries resumed supplying the house load when I cancelled the export. I've done the same this evening and again it's worked fine.
I wonder if, because the firmware has been updated I should regenerate the API and reconfigure Wonderwatt, but I'm clutching at hairs I suppose!
J1m We can't see anything obvious wrong to be honest.
We have a successful export for you for Sunday afternoon from 16:30 - 20:13, see our diagnostics log.
You should also see these instructions from your Giv inverter log. We also spotted a charge instruction on Sunday night into Monday morning.
Are you only having issues with discharges/exports?
Could you at least enable a timed charge and test this out?
If that all works, you could then try a 10 min export or so.
Additionally, when you create an export via the Giv app, could you show us the Giv inverter logs for the export please? We have a suspicion something may have been changed with Giv's implementation of the API wrt Timed Discharges and Timed Exports and treating these differently for different Giv inverter / firmware combos.
Charging via WW schedule has been working fine. I can try scheduling a WW export tomorrow, unfortunately I've no got much battery charge left this evening. I will re-enable my WW overnight charge tonight, then set my WW export to run again tomorrow evening and report back. Should I try regenerating the GivEnergy API and resubmit it in the WW config first?
Regarding the log, I'm appending the GivEnergy log for the manual export I did yesterday between 18:16 and 22:20. Hopefully that is what you wanted? It does seem to repeat several commands but I did only set the app to export then 'play' once!

J1m GivEnergy updated my Inverter firmware and battery firmware.
What firmware version are you on?
Does it start with 3xx, 6xxx, 7xx, 8xx or 9xx?
Changes have been made by Giv about what Timed Discharge vs Timed Export does on these different versions.
See below.
We've been using Timed Discharge but may need to switch to Timed Export for some users. However, there are side-effects around it disabling Eco-mode automatically, and some prefer to keep Eco-mode on during export.
I would have expected a change like this to have affected quite a few more users on Giv systems when running exports via WW, so this may be just a red herring.
The log message in Giv does say "Discharge at full power", not "Timed Export" at full power.
- Edited
J1m It will be the inverter firmware that could be the issue here.
We'll try and see if we can change just your Timed Discharge to a Timed Export, and see if this works. We can then use a setting/toggle in Advanced "Use Timed Export instead of Discharge".
Actually, scratch that, can't see any Timed Export slots in the settings.
Thank you for your persistence in helping me with this. I hadn't noticed the quick export option on the dashboard. I set it running and stopped it after ten minutes as you suggested, and it worked fine and re-enabled Eco mode afterwards. My batteries are resuppling the house load as expected. Unless there is anything different with the way a scheduled export runs then it looks like it was just some weird anomaly. I will try a scheduled export later. I can't understand though why this happened, and why it was so difficult to get things back to normal despite inverter reboots etc. It wouldn't appear to be a WW issue though!! Thanks again...
The scheduled export went fine. Only a short one due to very poor solar today but it all went okay. Something weird obviously went on after the firmware upgrade on Friday, maybe GivEnergy did something when I reported the issue but all seems to be good now. Thanks for all of your help!
Unfortunately I've had the exact same issue this evening. I had my usual export set tonight for between 17:30 and 23:15. Exactly the same problem happened when it stopped - batteries appeared 'paused' and Eco was off on the app. House load being supplied only from the grid. Switching Eco on had no effect. Reset the inverter via the portal twice - no effect. Powered off the inverter and batteries and back on twice before it kicked back into life. The big difference this evening to my previous tests was that instead of the scheduled export stopping at the end of the scheduled time or being manually stopped, the scheduled export stopped tonight when it reached the set minimum soc, which was set in my schedule for 25% (it stopped at around 22:15). I wonder if this gives any clues? I'm very reluctant now to keep using the export schedule as it's such an absolute pain to get the batteries to supply load again, and I shall disable it for now and manually export. Advice appreciated!

J1m It just makes no sense.
We successfully set your discharge schedule times and enable discharge mode, and based on SoC and discharge rate estimated your SoC to be reached at 22:45. We therefore issued the following set settings commands (as we do with other Giv inverters to stop export):
Set Enable DC Discharge=0 (setting 56)
Set Enable Eco mode=1 (setting 24)
Set Battery Reserve limit=4 (setting 71)
Those all succeeded. It would be good to pass these details on to Giv and ask what settings they think should be set to stop the export and stop drawing from the grid for your inverter.
Especially given that this works correctly for other Giv inverters, we're a bit at a loss.
We don't touch the AC Enable=false when starting the export, and therefore don't set AC Enable=true back at the end, we basically don't set it.
That's the only differences I can see between our commands and the commands from your log set via the Giv app.
But this does look like some inverter issue? You said it worked a day ago without problem? And from our logs we can't see any failed commands. And nothing has changed in terms of instructions we send to end the export.
admin I've had issues since the inverter and batteries firmware were updated last Friday (inverter firmware to D0.191-A0.193, Battery firmware to 3017). The only time the exports have worked has been when the schedule has ended at the set end time, whereas it has failed when it's been ended by the set soc being reached within the scheduled export window. It hadn't clicked before that this was also the issue at the weekend. The 191.193 inverter firmware has only just been released having been on beta before, and it is not compatible with early Gen1 Inverters. Mine is a later Gen1 and is compatible, as confirmed by GivEnergy prior to them updating it. This firmware is 'faster switching' and I have noticed that there are less 'spikes' between battery/solar and grid - so I would be reluctant to revert. I wonder if, because it's 'new' that not many WW Giv users have it yet, and haven't experienced the issue?
I can try passing on your info to GivEnergy..
