Overvoltage protection for Fronius Symo 1+2 S

The overvoltage protection is supplied pre-installed and fully cabled, cannot be ordered separately!

For the Fronius Eco on the other hand, only the single variant is required for the type 2 overvoltage protection. Both measuring channels can also be used with the single variant. As is the case with the Fronius Symo, customers can choose between the single MPPT option and the multi MPPT option for the type 1+2 combi arrester, depending on whether only one or both measuring channels are used. Thanks to the adjustable, integrated remote signalling function, the system operator is notified automatically via the Fronius Solar.web online Portal* whenever the overvoltage protection trips. The plug-in modules allow for fast replacement in the event of a fault. Therefore only the individual module has to be replaced, rather than the entire overvoltage protection. The overvoltage protection is supplied pre-installed and fully cabled**.

*A Fronius Solar.web account is required.
**The option must be ordered at the same time as the inverter. 
***Applies to Fronius Symo.

Power optimizer P801

For 72 cells, 2 in series (landscape), 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.
