    Hello, Benjamin,

    Hissing sounds are not normal behavior. Tigo MLPEs should not be making any audible noises, clicking, or buzzing.

    I have created a ticket with our Technical Support team. They will be reaching out to you soon to work on the resolution.

    Thank you for contributing to our community.

    we have the same problem with a few optimizers. We observed that the optimizer whistles when the panel is shaded. During the shading optimizer starts shivering and stop with loud sound.

    Did you found any solution?

    Thanks for your answear.

    Hello Martin Jančík

    As per @...'s response, the Tigo MLPEs (TS4s) should not be making an audible sound. 

    For this reason, I have opened up a Support Ticket. An agent will be reaching out to you soon to assist in diagnosing the issue. 

    In the meantime, we greatly appreciate your patience with this process.

    Good evening,  

    My installer came over on Tuesday to resolve an issue with the CCA and he spoke to your support team to get it finally commissioned. The units started to appear to come online, however; I mentioned to him is it normal to hear a clicking sound from my panels. (note - this not do this before I had a every panel fit with TS4s). Therefore it must be the TS4s. 

    Not all of my panels have been recognised on the system and the ones clicking don't show any production, would this be a reason why they aren't being recognised or showing production? 

    My System ID is 94160, 

    Many Thanks

    Hello Daniel Thomson-Magoolagan,

    Thank you for your contribution to the Tigo Community!

    Since each system is designed differently, there may be an issue that is specific to the design. For issues like this, we strongly suggest Contacting Tigo Support and working with them directly to resolve the issue.

    I see that you have already done this, and one of our highly trained Engineers is reviewing data from the new CCA to see if there are any issues to be addressed. Please be aware that this may take a few day's worth of data to be accumulated and reviewed. In the meantime, we greatly appreciate your patience with this process and assure you that a resolution will be found. 

    Once you have received it, please feel free to share the resolution with the people in this conversation.
