Introduction
Solar energy is an abundant resource, but mismatch limits our ability to harness it. Inverters constantly chase unpredictable array MPPTs, leading to small losses in energy production that add up over time.
Strings are limited by shade, and many roofs prevent modules from being placed in their optimal alignment with the sun. Rapid Shutdown requirements must be met. Fortunately, Tigo has developed a product suite of cutting-edge solar optimizers, also known as MLPE's, (Module Level Power Electronics) as well as a suite of monitoring tools that address these problems and make solar energy viable for all.
The Tigo Advantages
Tigo Energy's technology has distinct advantages, making it a scalable and efficient option for addressing Rapid Shutdown and mismatch.
-
Rapid Shutdown - NEC 690.12 requires that the system be able to shut down in 30 seconds.
- Predictive IV and Impedance Matching: Each module operates at its maximum power point independent of shading on other parts of the array.
- Selective Deployment - Tigo technology can be deployed as needed, reducing balance of system (BoS) costs.
- Modularity - Tigo electronics are swappable and upgradable, eliminating the need to replace an entire module when a single diode fails
Below are the details of these advantages.
Rapid Shutdown
NEC 690.12 requires that the system shut down either manually via a switch or automatically in the case of a grid power failure. For details, see our article "Complying with NEC 690.12 Rapid Shutdown."
Tigo has the most complete and cost-effective module-level solution, NEC 2023 609.12 Rapid Shutdown. For a summary and links to more information, see our article "Application: Module-level Disconnect for Safest Solar."
Predictive IV and Impedance Matching
Tigo’s latest TS4 optimizer platform utilizes Predictive IV. This technology makes modules smart—each learns how obstructions like clouds and trees move across the sun's path on a year-round basis so that every module operates as efficiently as possible 365 days a year.
Additionally, when a module is shaded, a current tunnel is opened so that the modules producing less power do not affect the rest of the string. This is analogous to opening extra freeway lanes around accidents to prevent traffic jams. This applies not only to shade, but also mismatches caused by heat, soiling, and other sources.
Selective Deployment
Tigo's TS4 optimization technology works independently of the inverters in a solar system, and every module can be optimized as needed. If a tree's shadow falls on one corner of your roof, you won't have to purchase an optimizer for every module, but only for the shaded modules. This makes the entire solar installation cost-effective over its entire life cycle.

Modularity
Suppose you deploy a solar system, and everything runs fine for a few years. As time passes, that tree that first shaded only one corner of your house grows taller and covers more of the array. This costs you energy and additional payments on your electric bill. With Tigo's TS4 platform, you can purchase another optimizer for the affected modules. Tigo saves you time, energy, and money every step of the way towards solar power production.
