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.

When you wire solar panels in parallel, you raise the Current of the system, while the Voltage stays the same. Voltage: Total Voltage (Volts) = Voltage 1 = Voltage 2 = Voltage 3 = Voltage 4 Total Voc (Open-Circuit Voltage) = Voc 1 = Voc 2 = Voc 3 = Voc 4.
