Which risk increases when a photovoltaic array's combiner box neutral circuit lacks a proper grounding connection?

💡 Explanation

Increased common-mode voltage surge ensues because the grounding connection is lost; therefore, this raises electrical noise and potential damage to sensitive equipment rather than simply reducing efficiency, affecting power consumption, or suppressing harmonics.
