Possibility of connecting two inverters

[8urg33]

Hi everyone,
i thought about getting a second inverter, because the Growatt inverter takes very long to adjust to new output power requirements. It takes minutes to go from 100W to 800W for example. With second inverter I could gain more performance.
Here is the question:
Is there a possibly to provide another pair of login credentials for a second Inverter? Or GroBro is just able to handle one inverter?
Thanks for an answer in advance!

This is no problem at all, as everything is based on a unique per device serial.
You can add as many inverters and batteries as you want. 😄

Thank you for the quick reply. And let me specify my question:

SOURCE_MQTT_HOST: asdfghjkl.duckdns.org
SOURCE_MQTT_PORT: 7006
SOURCE_MQTT_TLS: true
SOURCE_MQTT_USER: QMN000…..
SOURCE_MQTT_PASS: Growatt
TARGET_MQTT_HOST: 192.168.198.183
TARGET_MQTT_PORT: 1883
TARGET_MQTT_TLS: false
TARGET_MQTT_USER: QMN000…..
TARGET_MQTT_PASS: Growatt
HA_BASE_TOPIC: homeassistant
GROWATT_CLOUD: false
LOG_LEVEL: DEBUG
DUMP_MESSAGES: false
DUMP_DIR: /share/GroBro/dump

how to provide this second set of credentials here?
(For source/target mqtt user/passwort)

Thank you and KR

Not entirely correct. GroBro has its own MQTT user, configured via environment variables, and each device has one named after its serial with password Growatt. User creation is done by you on your MQTT instance. Maybe check the configuration guide on this again. 😊

But this my current configuration of GroBro (of course with just one inverter) but I have to provide inverters name and credentials in this config don’t I? At least that’s how I did it and how it is working right now.
But I will check
Later today :)

GroBro is no MQTT broker, its a client like any other Growatt device. This said you create an account for GroBro and configure the credentials in the env variables. Then you create accounts for each Growatt device you have (like you already did). GroBro and your devices connect to your broker and GroBro starts its work.

Hi, I would like to connect two Noah and was already able to connet one of them. But I can't manage to connect the second. Could you please support?

Here are my settings:

Mosquitto-broker:

Grobro-addon:

The data of Noah with "50" is visible in HA. However, that of "40" is still missing.
I created a user called "grobro-ha" in HA. Is this the right way to go?
