Huawei Sun + Luna2000 + DTSU666-H
Content languageEnglish
Description
Caution: Huawei can only be queried by one device at a time. When transferring to the web portal, query errors can occur for a short time. My test setup: Sun 3KTL-M1 / Luna 2000 15 kWh / DTSU666-H / Loxone Miniserver Gen1. Connection directly via LAN cable. The query times are preset. If timeouts should occur, please increase these times step by step. In general, incorrect values can occur when devices are in standby mode: e.g.: Storage "it is loaded with 2.1 GW, or charge level with 6553.5%. This is a mistake by Huawei
Testing Software Versions: Inverter -> V100R001C00SPC148 Dongle -> V100R001C00SPC130 Battery -> V100R002C00SPC116

loxone template
OpenHello,
thank you for your addon! It is very useful to integrate the Huawei functions and to finally create a fully EMS system.
I'm struggeling a little bit with the status block for the "22 - Storage working mode status" readings. In order to not have to find out everything for myself, I was hoping is you would like to share some details and so I was wondering if you would mind to copy (and make a little *.loxone template) for all the basic functions that you show in your print-screens on the loxone library page.
This would be very helpful for me and save a lot of time.
Thank you in advance,
Valentijn

SUN2000 8KTL- M1
OpenHi, thanks a lot for your template!!
I have just seen it is tested for SUN2000 3KTL- M1. However, I have the "8K" model. Probably one is a 3kW an the other 8kW.
Do you think that I can use your template for a "8K" model?
Thanks in advance for your support.
Kind regards
Santiago, from Spain.

I'd be very appreciate and Thanks in Advance.

Found the Modbus definitions at Huwaei:
Energy Storage Status: https://support.huawei.com/enterprise/de/doc/EDOC1100387581?currentPartNo=k004&togo=content§ion=k004 Register 37762 0: offline 1: standby 2: running 3: fault 4: sleep mode
Storage Working mode: 0: Adaptive (Fixed charge/discharge/Maximise self consumption) 1: Fixed charge/discharge 2: Maximise self consumption 3: Time Of Use(LG) 4: Fully fed to grid 5: Time Of Use(Luna)
EMMA (Netz) Grid Werte auslesen
OpenIch bekomme die Batteriedaten und WR Daten in Loxone super rein, nur kann ich die Grid Daten nicht empfangen.
Woran kann das liegen?
Welche Befehle benötigt die LUNA2000 S1 für das AC Laden?
AC Laden Ein/Aus (47087)
Storage Workmode (47086)
und die Leistung (47242) vom Netz.
Die Batterie lädt leider nicht vom Netz.
Ist aber in der Huawei App aktiviert
Dankeschön!
