A Guide to Solar Inverters: How They Work & How to Choose Them

The first part is the power optimizer, which handles DC to DC and optimizes or conditions the solar panel''s power. There is one power optimizer per solar panel, and they keep the flow of energy equal. For example, with a standard string inverter, if one solar panel produces less energy, all the solar panels in that string will produce less energy.
