Solaredge Optimiser, portrait, 850W, 125V, 1.2m cable

The SolarEdge Power Optimizer is a DC-DC converter that optimizes energy yield from solar panels by performing Maximum Power Point Tracking (MPPT) individually for each panel. The specifications you have provided, such as "portrait," "850W," "125V," and "1.2m cable," are all related to the product details of the SolarEdge Power Optimizer.

"Portrait" indicates that the orientation of the power optimizer is in the vertical or portrait position. "850W" refers to the maximum DC power that the optimizer can handle, which means that it is compatible with solar panels up to 850 watts. "125V" refers to the maximum DC input voltage that the optimizer can handle, which means that it is compatible with solar panels with a maximum voltage of 125 volts.

Lastly, "1.2m cable" indicates the cable length of the power optimizer. The power optimizer comes with a cable that is 1.2 meters long for connecting the optimizer to the solar panel.

Overall, the SolarEdge Power Optimizer is designed to work with a wide range of solar panels and is a key component of the SolarEdge system, which maximizes energy production and enhances system performance and monitoring capabilities. The choice of portrait or landscape orientation depends on the solar panel installation, and both orientations are supported by the SolarEdge Power Optimizer.
