Tigo’s RSS Signal Detector is a functionality testing device for sensing the power line communication (PLC) signal from the Tigo RSS Transmitter to the TS4-F or TS4-R-F (Fire Safety) units. The Detector is used during installation to verify that the TS4-F units are receiving the keep-alive signal from the Transmitter. This is the handheld, failsafe tool to confirm that your PV system is compliant with NEC 2017 690.12 rapid shutdown specifications.

SolarEdge Power Optimizer P850 

Series connection of 2 x high power or bi-facial modules 

 For high power/bi-facial, 2 in series, 125V, output cable length 2.2m, input 0.16m

The SolarEdge power optimizer is a DC/DC converter which is connected by installers to each solar module, turning them into smart modules. The SolarEdge power optimizers increase energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually. Furthermore, the power optimizers monitor the performance of each module and communicate performance data to the SolarEdge monitoring platform for enhanced, cost-effective module-level maintenance. Each power optimizer is equipped with the unique SafeDC™ feature, which is designed to automatically reduce modules' DC voltage to a safe level whenever the inverter or grid power is shut down (unless connected to a StorEdge inverter operating in backup mode).

The MPPT per module allows for flexible installation design with multiple orientations, tilts and module types in the same string.  When working with SolarEdge inverters, the power optimizers automatically maintain a fixed string voltage, allowing installers even greater flexibility with longer strings and strings of different lengths in order to design optimal PV systems. The SolarEdge power optimizers are compatible with c-Si, thin-film, and high current modules and have a 25- year warranty.
