Micro-inverter or string-inverter?

[alihje]

Hi!

Is there a quick way to know whether the inverter you have chosen in Systems is a micro-inverter or a string-inverter ?

Thanks.

This depends on how you define a Micro or a String inverter.

To my opinion, a micro inverter is suited for one module, i.e. with a Pnom of less than, say, 300 W.

In the present time, by "String inverter", people usually talk of inverters suited for 2-4 strings, i.e. some few kW.

More than 15 years ago, some inverter manufacturers called "String inverters" devices for which all the safety components (usually present in the roof junction box) are included in the inverter. This is the definition of PVsyst.
