It would be helpful to keep your question in one place and not all over the forum. If someone can help, they will reply although this is a UK forum and therefore might have different technical requirements to those in Pakistan.
It seems to be to do with how your inverter is set up and not knowing that, it’s not possible to suggest a solution. Also, as with others, you seem to be based outside the UK and so there may be technical differences in the specification. Sorry
I hope one of our community members are able to help answer your question based on their own experiences, but we do have a lot of topics related to Solis, I’ve linked below to just a few of these but you can find lots more by searching ‘solis’ on the home page of the Forum:
Solis also have a really handy contact page if you wanted to reach out to them directly too.🙂
