Tools and Overview

 Designing a Smart Module system consists of 3 steps:

1. Determining the Smart Modules electrical layout
2. Determining the number of Gateways 
3. Determining the number of Cloud Connect Advanced units (CCA) / Cloud Connects / Management Units (MMU)
   

Tigo has created a free online design tool to assist in calculating string length and determining the number of Gateways and Cloud Connects/MMUs needed.

For a detailed training on designing a Tigo system, go to Tigo Academy or download the presentation or guide below.

Note: Always have your entire array (or at least all modules on the same MPPT) optimized with Smart Modules or retrofit optimizers.

If using TS4-O or TS4-L, it may be possible depending on your site layout, to use optimization selectively on a string.
