Solis Hybrid inverter and forced discharge not working due to "Energy Storage Control Switch" #962

Open spetrie13 opened 5 months ago

spetrie13 commented 5 months ago

Describe the bug Justed moved from Go to Octopus Flux, but discharge did not take place as planned during 1600 to 1900 time slot. Charging overnight seems to work, but not discharge. Plan shows correct charge and discharge plan.

"Energy Storage Control Switch"

Expected behavior Predbat indicates correct discharge in the correct period in the plan, but the "Energy Storage Control Switch" has the incorrect setting preventing the discharge. On discharge the "Energy Storage Control Switch" should be set to "Self-Use"

For the solis inverter you only need to set the "Energy Storage Control Switch" to "Self-Use" and set the charge and discharge timers to enable charge and discharge.

Predbat version V7.16.15

Environment details

Screenshots "Energy Storage Control Switch" to "Self-Use": image image image

Enable Predbat and it changes the "Energy Storage Control Switch" image Battery returns to just discharge to house image

Are you able to test this fix from a branch 'https://github.com/springfall2008/batpred/tree/solis'

you need to copy predbat.py into your apps directory (overwrite the existing one)

Will try tomorrow.

Scheduled discharge did take place in spite of the error messages.

Can you please update from the branch again, hopefully I fixed this issue

spetrie13 commented 5 months ago

Charge worked last night (0200 today), but discharge did not work. image Not sure why discharge time starts at 0000 and ends at 1901. I would have thought it should have been set to start 1600 and ends at 1900 as the plan indicates. I believe and an overlap of the charge and discharge times cause the issue? Should we set the discharge start time when setting discharge period? If I manually set the discharge time to 1600 then discharge starts with no other changes. image image

springfall2008 commented 5 months ago

Hmm okay, the overlap has no impact on GE inverters so I'll see if I can fix that one for you

springfall2008 commented 5 months ago

I've updated the branch with a potential fix, can you test again please?

spetrie13 commented 5 months ago

Seems to work. Just restarted Appdemon and set discharge hours to 0

It set the start and end discharge times:

Hi,

Looks like the latest version predbat is not setting the Solis discharge start time again. Set to 00:00:00 to 19:01:00 when it should have been 16:00:00 to 19:01:00. It overlaps with the charge time so does not discharge.

Hi Trefor,

Solis inverter discharge not working with latest update. The discharge start time is not being set and results in an overlap with the charge times and discharge does not take place. (Quirk of Solis not allowing time overlaps) This was working in the solis test branch.
