Sunsynk
Based on recent customer reviews, Sunsynk receives sharply mixed feedback shaped largely by after-sales experiences. Customers consistently mention frustration with extended repair turnaround times on inverters and batteries still under warranty, with a recurring theme of poor communication and limited feedback from the support team while units sit on the bench awaiting parts. The Sunsynk Connect app and notification reliability also draw criticism. On the positive side, customers occasionally praise individual staff members, professional repair handling when it goes well, and the underlying quality of the hardware itself.
