Growatt Export - limit ignored

krustydad

Hi all, first post here.

Growatt MIN 5000TL-XH
10kWh ARK 2.5A stack

Firstly, wonder watt is great - so simple to use, and currently the charging window is working great.
Octopus had a Saving Session today, so I setup a export with 70% battery limit.
The export started, but continued past the 70% down to 65% where I was monitoring so disabled the schedule directly in Growatt server.growatt.com

I see a previous thread highlighting a limitation with GivEnergy, is this also an issue with Growatt?

I have tried several charge limits, and these are also ignored. I set 50% Wednesday night, and 30% last night, and it continues to charge to 100%.

WW Log shows the API is being called with the limit.

Growatt shows the charge is continuing to 100%

Is there some configuration required in the Growatt UI to enable sub-100% charging/discharging?

Hey, I Have same issue with my 9000tlx-XH . I have a post under feature request, where admin replied that the XH integration for charging limits is somewhat different for XH inverters (not connected to timeslots) and needs looking at.

Thank you for responding. That explains what I see in the GW interface then, where the limit is separated out from the TOU slots

krustydad exactly. Have been struggling with that a lot as many threads on internet were referring to setting it within each of the timeslot but for some reason , not available for TLX (-XH?) versions.

Question for you maybe. Think it wasn’t doing that before but mine now keeps going to waiting mode / off-grid in evening. No longer showing the batterie. But then also the batterie settings and timeslots etc disappear from the menu, making it impossible to set it to charge in the night for example .. ( so at night also WW failing to set it to charge) : you have this as well ?

Hi Jorrit

Sorry, I didn't see your reply.
I am not seeing the same issues as you in the UI.

Through WW I have the charge schedule set every morning 02:00 - 04:55
I see this in the TOU slot 3.

I have tried not to mess with anything I am not sure of in the GW UI - fear of making things not work is a great boundary for me!

krustydad thanks for replying. No idea why happened , but after a battery BMS
restart problem solved. Think my inverter somehow stopped seeing the battery and therefore went off-grid in evening. Thanks
