Against the backdrop of global PV installed capacity exceeding 2TW, safety has become a core pain point restricting the development of the industry. Leakage and fire risks of traditional PV systems have not been effectively solved for a long time, and the mandatory implementation of regulations such as NEC 2017 in the U.S. has made module level fast shutdown technology a new rigid need in the industry. 2025, YRO successfully passed UL3741 certification with its technological breakthrough.

From computers to HVAC systems, our electronics rely on transient voltage suppressors for safety. But what happens when this critical protection fails? Understanding warning signs and consequences is crucial for protecting valuable electronics.

In power system lightning protection, the lightning arrester's installation location is crucial for transformer protection.

As the world's energy transition enters a crucial decade, every international exhibition is a crossroads of technological innovation. Today marks the final day of the Yiwu Solar Photovoltaic and Energy Storage Application Products Expo. YRO sincerely invites global purchasers, engineers and project decision makers to make the most of the last day, and visit booth E1-B11 to jointly explore new energy and industrial grade power solutions.

Modern power systems are threatened by transient voltage surges. These short, high amplitude voltage pulses, usually lasting from nanoseconds to milliseconds, caused by lightning strikes, grid fluctuations or the switching of industrial equipment, can silently destroy precision electronic devices ranging from laptops to photovoltaic inverters. Although circuit breakers are crucial for preventing overloads and short circuits, they are powerless against microsecond-level surges that bypass their mechanical tripping mechanisms. This article will delve into the functions that lightning arresters can perform but circuit breakers cannot, as well as why both are indispensable in electrical protection.
