What Is 1500V DC in Solar Systems?

A procurement guide to 1500V DC solar architecture and related BOS component selection.

What Is 1500V DC in Solar Systems?

1500V DC solar architecture allows longer strings and fewer home runs, but all cable, connectors, fuses, breakers, SPDs and combiner boxes must be rated for the voltage.

1500V is common in larger commercial and utility systems. It can reduce BOS quantity, but it also makes rating coordination more important.

How buyers should read this

Buyers should not mix 1000V and 1500V assumptions in one DC package.

  • Module string Voc
  • Inverter max DC voltage
  • Cable rating
  • Connector rating
  • SPD and breaker rating
