I have it set up with home assistant on my Solis inverter - if you need help just ping me, I can help you with it. Basically you just need to pull the data into home assistant and assign a few variables, then set up an automation to send it to pvoutput. Easier than it sounds! You can also pull solar forecasts into home assistant which will give you an easy way to view the data from solcast or similar.
One thing you’ll need to do is request API access from Solis (just submit a ticket) as that is how home assistant will grab the data. There are other more involved ways that allow you to directly control the inverter but that requires messing around with modbus and is a big step above… API will suffice if all you want is to bring data into home assistant.

While you are at it you may want to submit another support ticket for remote control access from your phone - this lets you control all the inverter settings (such as charge/discharge periods and rates) from the phone rather than directly from the inverter itself.
