What does ISC mean?

Short-circuit current a module can deliver; in PV design it helps verify equipment ratings, wiring, and safe operating limits.

How is ISC used in solar design?

This term affects electrical design, string sizing, code checks, equipment ratings, and safe installation. In solar, the numbers are not decoration; they are the guardrails.
