This article addresses the Tigo TS4 MLPE's out-of-the-box functionality. By default, the TS4s ship in either an ON or OFF state. Depending on the model, some TS4-4s allow full module voltage to pass through when first connected to the module!
This becomes particularly important if you shift installation from one product to another or have experience with other MLPE installations.
The TS4-A-O, TS4-A-S, TS4-X-O, and TS4-X-S require the Cloud Connect Advanced (CCA) and Tigo Access Point (TAP) for data and rapid shutdown.
The TS4-A-F, TS4-A-2F, and TS4-X-F require the RSS Transmitter with Pure Signal Technology for rapid shutdown operation.
