We recommend an oversizing ratio between 1.1 to 1.35, depending on your solar project. For example, placing a 600W microinverter on 2 x 415W solar panels is a normal use case for a balcony solar system.
For an 830W solar system, you would need 2 x 415W solar panels, 2 balcony brackets, and 1 x 600W microinverter.
