The first is the power optimizer that attaches with one bolt to each solar panel.
Solar panel power optimizer.
Optimizers take dc energy regulates the output of the module and delivers energy to the central inverter for final dc to ac usable energy conversion.
It is a module level power electronic mlpe device that increases the solar panel system s energy output by constantly measuring the maximum power point tracking mppt of each individual solar panel and adjusts dc characteristics to maximize energy output.
The solaredge power optimizers increase energy output from pv systems by constantly tracking the maximum power point mppt of each module individually.
The solaredge power optimizer is a dc dc converter which is connected by installers to each solar module turning them into smart modules.
A power optimizer is a combination of both a string and micro inverter.
As your solar panels produce electricity the power optimizers condition the electricity from your solar panel optimizing the voltage before sending it down to the inverter for conversion.
Description solaredge p320 power optimizer get the most power from your panels with the solaredge power optimizer.
The second is the solaredge inverter itself specifically designed to accommodate the string of solar panels.
