What does PV Module Rating mean?

A PV module rating is the electrical performance value assigned to a solar module, including power, voltage, and current ratings measured under defined test conditions.

Why do module ratings matter for MLPE and inverter selection?

Module ratings help determine string length, optimizer compatibility, inverter loading, and clipping risk. The wattage number gets the attention, but voltage and current are also very much invited to the design meeting.

How it relates to Tigo

Tigo MLPE selection depends on module power, voltage, and current ratings within product limits.
