Hi, I fully agree with you about the logic or wrong logic of the inverter setup. I'm managing all the settings with Home Assistant integration. It means I'm using automation in Home assistant to keep it doing what I want. I'm changing "Inverter Discharger To Grid Enable" switch and "Energy Use Mode" switch together. I need to use HA while you need to change more values based on sensor data... I worked also with SolarAssistant team they were very helpful to connect Inverter and that time made a change in system to be able to see the back feed to the grid, however I was not able to set up automation which would work with the logic of the MUST inverter.

Thank you for your feedback! I was able to set this up. Now it is running really good and I'm impressed also. It was a need to improve my knowledge about HomeAssistant/MQTT/DOCKER/DEBIAN, however it was worth it. I will describe in short what I did, if somebody want to do the same, maybe you don't need to read/watch so much... 1. I used an old laptop what I had in house, however you can use anything similar to raspberry pi. 2. Installed Debian on the machine 3. Installed Home Assistant Supervised -> while with this option you have full HA and the hardware you can use also for other things (compare to operating system) 4. Created an MQTT broker -> HA\Integration, really good tutorials on YouTube.com 5. Created InfluxDB and Grafana ->HA\Addon, really good tutorials on YouTube.com 6. Downloaded the docker-must-homeassistant. From GitHub: https://github.com/dylangmiles/docker-must-homeassistant 7. Edited the mqtt.json to my server and credentials created in point 4. 8. Compiled the Docker image downloaded in point 6 and Started based on description 9. Connected my laptop to Must inverter with the cables and after few seconds the Sensors value was updated in SA and Stored in InfluxDB. After I just created a Dashboard in Grafana.

Hi, I was able to install Solar Assistant - did not made any configuration with integration, and also docker-must-homeassistant. I want to try option 2. If I run the "docker -compose up -d" it is telling me that must-inverter-mqtt-agent-inverter_1 is up-to-date. My question is how can I connect it to solar assistant? Do I need to edit some config files like /src/inverter/mqtt.json. If you have anything which is describing the process a bit more in detail it would be appreciated... Thank you!

To summarize for the the people who want to have similar setup (basically it works based on documentation): 1. With SBU/LBU/OSO setup it is not possible to feed just solar energy back to the grid. It will take/drain also the batteries. 2. In SUB/LBU/OSO it is possible to feed back just the solar power, however in this setup the battery is just active when utility power is not available 3. in SOL mode you can't use setup 9 feed back to grid, more island solution, with bypass possibility. I tested out all of this options. Thank you for your comments.

Thank you I will check that!

Hi, thank you maybe in this case I need to try it, however if I have the setup what is above and I set up 20 for 90% SOC. For me it would mean: 1. Feed back 10% battery power to grid, at day time after you charged the battery (sunny day) 2. Do not use anything from 90% battery at night time, when I want to use battery power, while I have grid power and don't want to drain below 90%. Is this assumption wrong? Inverter will use the 90% SOC at night with this setup? Thank you for your feedback

Hi, my issue with that is, than I can't use my battery energy at night, what was the intention. I want to have not a backup, however more island solution. If I will setup 80-90% SOC it would mean that I'm not using my battery power at al, while he will feed back in to the grid 10-20% and after in the night he will stop discharging while I have grid power. Or maybe I'm wrong?

Hi Team, I was reading quite a bit around setup of the MUST inverters. I would like to ask some questions, maybe you can give me more light in to the darkness... 1. I want to have a SbU (1) - Solar/Battery/Utility setup 2. I like to use Solar power first on loads and after charging - LBU (5) 3. I want to charge the batteries only with solar power - OSO (10) 4. And if on top of the load and the battery charging I will have some energy left I want to send back to the grid - GRE (9) For battery I have information from manufacturer LiON (14cellls - 3.3V cutoff and 4.1V max, 46.2V cutoff and 57.4V max) My setup is: 17-57.3V, 18-57V, 19-46V, 20-47.5V, 21-54V My issue is, when I set up GRE (9) -> it will check with LBU setup parameter 20 and if it is higher than 47.5V start to feed solar and battery power back to the grid. Which is not my intention to do. Do you have any recommendation? Or any idea what could I set up differently(LBU/BLU)? Or maybe I'm completely wrong? Thank you!
