    "Great string inverters for experienced installers"

    Reviewed Jan 09, 2022

    We exclusively use SMA string inverters for customers and have found them to be highly reliable and configurable. They work well with both Tigo and SMA branded rapid shutdown modules. Plus, the built-in SMA shade fix MPPT string level optimization eliminates the need for optimizer modules on each panel. The reviewers that had issues with their inverters all noted they had panel based optimizer modules. SMA inverters do not need separate optimizers, so I'm not surprised the inverters fought with the optimizer modules. That's just their lack of understanding and experience with the SMA system. I really like that SMA offers free lifetime monitoring via the web and app for both installers and owners with remote diagnostics and management being very straightforward. The few times I've had to contact customer service were fast and efficient with an engineer on the other end that could answer very specific questions with depth. Inverters are highly sophisticated and have developed to the point they are beyond DIY regardless of brand.

    Very high quality inverter. Very happy with the system generation and customer service.

  • ""Design flaws and poor customer service""

    Reviewed Oct 08, 2021

    I had the exact same experience as pinkard_manaus except worse. My Tigo optimizers stopped showing up on the SMA Sunnyportal or the Tigo Energy websites. Both SMA and Tigo said they could see my data but it did not show on the websites. After many times where my system would go into rapid shutdown and having to put 4-5 panels against my garage wall to get the 125Volts needed to start the system I was extremely frustrated.

    Neither SMA nor Tigo Energy wanted to take responsibility for the issue. After more than 8 months SMA finally sent me an external CCA to replace their internal GIB board. After installation I haven't had an issue for going on 10 months.

    I only wish customer service would have listened to me and tried to fix the problem. I also had the problem where every time I called I had to basically start the entire process over again.

    I managed a technical support desk for 20 years and I would rate SMA as the worst I have ever deal with and I have worked with 100's.
