Solar Testing Guide - Electrical Continuity Verification

Electrical continuity refers to a complete path for current flow within a circuit. Continuity tests for PV systems verify that electrical current has a continuous low-resistance path to return to the source and to enable ground-fault protection devices to detect and to  interrupt fault currents.

Technicians regularly perform continuity tests during PV project commissioning and troubleshooting. The new Solar Testing Guide chapter describes the relevant tools, techniques, and safety considerations for continuity tests.
