    Overview Overview Tigo TS4-X module level power electronics (MLPE) enable monitoring, rapid shutdown, and optimization of solar modules. TS4-X has 3 models with different feature sets: TS4-X-O (Optimization, Monitoring, Rapid Shutdown), TS4-X-S (Monitoring and Rapid Shutdown), and TS4-X-F (Rapid Shutdown).

    Electric Code (NEC) ANSI/NFPA 70 and/or local electrical codes. When the photovoltaic array is exposed to light, it supplies a DC voltage to the Tigo TS4 units and the output voltage may be as high as the PV module open circuit voltage (VOC) when connected to the module.
  • Page 8 Safety Do not connect or disconnect under load. Turning off the inverter and/or the Tigo products may not reduce this risk. Internal capacitors within the inverter can remain charged for several minutes after disconnecting all power sources. Verify capacitors have discharged by measuring voltage across inverter terminals prior to disconnecting wiring if service is required.

    CCA, which requires an internet connection. This setup is necessary for system monitoring, warranty eligibility, and code compliance. A CCA should control all TS4-X-O and TS4-X-S on all strings connected to a specific inverter or MPPT. Install the CCA near this inverter with access to AC power and the internet. Ethernet and Wi-Fi are built in.
