[RE-wrenches] Tigo inverter experience

Thu Feb 13 18:05:06 PST 2025

We've had catastrophic failures with the RSDs and have heard from plenty of others that have had the same.  The company denies and deflects and blames the installer until you are fatigued.  A product that uses power line communication that can start burning when the signal gets corrupted should not be allowed to remain on the market.

CAUTION: External Email.
I do not have a lot of experience with Tigo equipment, almost all using their optimizers with CCAs and TAPs.  The 2 things I can say is after getting my head wrapped around the setup and commissioning process (which is not the most intuitive process), I haven't had much trouble with them (again only have maybe 4 or 5 systems out there), and their tech support is generally very available and very knowledgeable and helpful, impressively so. Otherwise I can't speak much to their durability, reliability, or functionality.

Hi Dave
I haven't tried their micro inverter or ESS, but so far all the products that I've used from Tigo including the RSD switches that melted have been problematic. Personally, I wouldn't use their products.

Hi All,
I am curious if anyone has any experience with the Tigo inverter and energy storage system. It looks very similar to the SMA setup, but maybe a bit farther along in development. Even as just a simple string inverter, it seems fairly reasonably priced.

Cheers,
Dave
