What is maximum DC input current?
This maximum DC input current refers to the maximum flow of electric current that the inverter can pass without getting overloaded. We must check the current range of the solar panel and make sure it does not exceed the maximum range to avoid overloading the inverter.
Can SMA inverters be used with high-current modules?
SMA inverters can easily be used with high-current modules. The absolute limit is the maximum connectable short-circuit current (I SC PV) of the inverter. The maximum input current (I DC max) of the inverter is not an absolute limit in the selection of the PV module. All SMA inverters can exceed I DC max without any problems.
What is I DC Max?
