Solar Installation Inverters
The inverter is the device that converts (inverts, technically) the direct current electricity produced by the solar array(s) into usable alternating current, or AC electricity. There are several different types of inverters a solar installation might employ. String inverters are the simplest, most mature inverter technology, in which the DC from groups of solar panels linked in series are fed into the inverter. The inverter puts out AC electricity which is then fed to the home’s electrical infrastructure. Micro-inverters are small, modular inverters that are furnished behind each solar panel in an array and effectively compartmentalize the AC energy production of each panel so that the reduced production of one panel does not affect the output of the entire system (i.e. if one panel has shade on it from the tree, it will not affect the other parts of the system)
Keep in mind: Some inverter companies such as SolarEdge offer power optimizers, which essentially act like micro-inverters on a string-array.
