WW tried to charge & discharge at the same time

webmink

I just had a serious issue with my Growatt SPH3. I scheduled a battery discharge for Saturday evening to be ready for the Dave Dip I discovered however that my battery was charging, not discharging. I caught this before too much money was wasted and gave the Growatt inverter commands to stop it charging.

I looked into the logs and found that WW had tried to command both charging and discharging for the same time. When I looked at the schedule it seemed correct. Then I noticed in the schudule a discharge reques half-hour early for this morning that I had previously scheduled had reappeared on the screen.I could not delete it but using "clear all export" seemed to work. Sadly WW still tried to execute it in the early hours (fortunately if failed).

I am very concerned about what has gone wrong here. Any ideas?

I have e-mailed screenshots to the labs address, for some reason I can't embed them here today.

webmink Could you let us know the timestamps please?

This is the cancelled export slot that was attempted anyway:

webmink Could be that the export was cancelled too close to the trigger time?

Looks like a clash of slots, possibly because Agile prices were below threshold?

The failure really comes from a clash of times on the inverter.

No. it was all set up around 5pm as I recall. I also found that the discharge slot at 00:30 kept reappearing even after I cleared it, which I did around 20:45 when I was dealing with the earlier issue. At this point I had not given any direct commands to the inverter.
