String Inverter

Solar inverter connected to a string (or strings) of modules — the dominant inverter type for utility-scale and commercial solar in 2026.

A string inverter accepts DC input from one or more series-connected strings of PV modules and outputs AC power. Modern utility-scale string inverters are 100–350 kW per unit. They dominate utility-scale solar (64% of 2025 shipments) due to faster commissioning, better serviceability, and superior bifacial-tracker compatibility versus central inverters.
