Hello, friend.
Do not expose your privacy in a public forum. It is possible that the fusion solar system is malfunctioning or it is the cause of your inverter itself and you can try upgrading to the latest version. You will need to seek help from the PV Centre to locate the fault. You can send an e-mail describing your problem and including your SN number to the following e-mail address.
