The operating principle of the inverter is to generate seven levels of voltage. ie, Vin, Vin/3, 2Vin/3, 0, -Vin/3, -2Vin/3, -Vin. The intermediate voltage levels in the output voltage can be obtained by proper switching.

UL 4703 covers three voltage classes: 600 V, 1000 V, and 2000 V. The 2000 V rating is the current industry standard for modern string inverter and DC optimizer systems, offering greater design flexibility and headroom for high-voltage string configurations.
