String inverters of up to 10 KW are mostly used for smaller, personal rooftoop systems. Larger string inverters on the other hand are also used in PV systems on bigger rooftops or in solar arrays. The inverters differentiate mainly in whether they have a transformer or not. But also the number of MPP trackers and whether they are one-phased, two-phased or three-phased are important differentiating metrics.
