  • Release 441 - Scheduled Export fix

JMA @admin

Can you comment on my original post - is this possible to fix also for import ?

Below is another good example

2:45 am: battery charged at desired level, but house will keep pulling from grid until 5am (smart charging on)

This happens more and more often as we now get more sunshine.

      JMA Makes sense yeah, although this should probably be an option/toggle for import.

          I have asked for this from GE as its always been illogical, but they say it works as it should but never explained why they think such. To be exporting to the grid and then importing from the grid in the same HH slot is not something I need.
          If you can fix this it would be a winner.

            4watts We’ve already addressed this for export as a default - for Giv users.

            It will calculate when you hit target stop SOC and will reset back to eco at that time, which may be before your original end time.

              Can you add that for import (with a toggle) ?

                  Last night’s adjusted discharge seemed to stop early, target was 15% but stopped around 30%. Not sure why this was, would a change in the solar power forecast affect this?

                    Ifgow Nope solar forecast doesn’t affect this, it’s based on your discharge rate and battery SoC at the start of the export. For which we then calculate the expected adjusted end time.

                    Some users split their export windows into two (5 mins apart) with a new SOC condition to overcome this.

                        admin Would it be easier to have a toggle so adjustments aren't applied?

                            Ifgow We could do yeah - though it would mean that you may risk drawing from the grid during a time when the prices are expensive, as we would only revert Eco back at the end of your export window.

                                admin last night again export stopped about 3h early and about 40% higher than stop export SOC - surely that can’t be right?

                                    Ifgow Your SOC was 88%, your target stop SOC specified was 15%, at a discharge rate of 3.0kW and a battery capacity of 9.5, it would take roughly 138 mins, or at 2:23.

                                    It does look like your battery discharge rate was 1500W if I read the chart correctly?

                                    It might make sense for us to set that to max rate, which the calculation relies on.

                                        admin I’ll try that, but one battery mantra seems to to charge/discharge at around 50% to prolong the life of the battery. Could the calculation not read the set discharge. Rate and use that value?

                                            Ifgow Yep - we can do. We'll make it an option for Giv users. Much trickier to do on Growatt due to undocumented and not officially public API.

                                                admin sounds good, have reset battery rates for now, and left settings to run tomorrow morning if the solar energy prospects meet the criterion.

                                                  @Ifgow This has now been rolled out and is available in Release 640.

                                                  By default, for Giv users the export schedules will calculate the adjusted end time based on the currently configured discharge schedule.

                                                  If toggled off, 100% discharge rate will be used.

                                                    I'm sorry but, having read carefully through this thread, I still don't understand why my Scheduled Discharges are stopping earlier nd at higher SOCs than set. My AIO charge and discharge is set to 6kW, as per specifications. I'm away from home with only fridges and freezers running and I want to get through 2 complete charge and discharge cycles per day to get max benefit from Agile and solar but the discharges never complete.
