Very good video what is difference between Mico and String Inverters



Micro vs String Inverter



You have to watch it before install a solar system.


Enphase MI system is much expensive than String inverter,

even more than Optimizer system.


But, String inverter system need 6+ panels in series, it means there is a minimum number of panels under similar sun-light condition. but, MI system do not have the minimum requirments, technically 1 panel.


so, if have small zone & multi zones (more than 2), MI should be better

except this condition, There is no advantage via the extra cost
