Tigo TS4-A-O | Optimization, Monitoring & Rapid Shutdown | 20A

Tigo TAP is required for rapid shutdown and Tigo CCA is required for monitoring with TS4-A-O.

Optimization is a Flex MLPE function available as an integrated modular junction box base (TS4-O) or as an add-on unit (TS4-A-O). Design using unequal string lengths, mixed orientations, or areas of mismatch. Install in shaded areas with a reduced setback ratio. In addition to optimization, the TS4-A-O enables module-level monitoring, and rapid shutdown in compliance with NEC 2014, 2017, and 2020.

Tigo TS4-A-O are great!

I now have a total of 32 of the rapid shutdown optimizers. I am in the process of redoing my whole solar system and purchased 13 more. They work very well in areas where you have shading. I live in a residential area with trees all around. This has been the key to being able to run my house off grid. I have sold the old panels and have purchased 32 new 405 W panels. I also recently purchased an EG4 12,000XP. This has the electronics for running the small Tigo transmitters. I do have the separate unit also. These are not inexpensive, but are needed to use on solar panels in a residential setting if you don’t want to use micro inverters. These make Solar Panels safe on your roof if there is a fire. They can be shut down immediately with the rapid shutdown feature. I am sold.

The optimizers have made a difference. I might suggest to add any additional equipment that may be needed to get the full functionality of the optimizers on your website.

Amazing upgrade for my system.

These optimizers are amazing. Our installation has 3 strings that depending on the conditions all get various amounts of shading due to very large trees. Since installing optimizers on all of the panels we are averaging 30-35% additional output compared to not having them installed. Essentially this is about equal to adding a 4th string at a fraction of the cost.
