Hello, my first post here. I haven’t yet configured home assistant, still reading to prepare. But I have found something I wanted to share with you.
As you know, recent inverter firmware has blocked the modbus tcp port from local lan access and is only available when connecting to the wifi access point of inverter (SUN2000…). I don’t know if what I am reporting was working before or if it works for all models, but it does work for me and inverter SUN2000-5KTL-L1 with firmware V200R001C00SPC124 (latest). Using latest android fusionsolar app (version is 6.23.00.125) you can enable again modbus tcp from local lan access. Go to device commissioning, connect to your inverter (needs installer password), then go to Settings → Communication configuration → Router connection settings. Then, select your local wifi access point, enter your password and check the option “Local Oamp;M”, then click Connect. It will reconnect to your access point, but this time port 6607 is open on local lan. If you revisit the same configuration page, the option seems it is disabled, but port is indeed open (and works, I tested and got data).
I attach a photo taken from the phone (for some reason android screen capture was disabled in this menu) to see the option.
Local Oamp;M should have been Local O&M actually but some text translation failed. O&M stands for “Operation and Maintenance”.
Hope this helps others.
