In November, solar power inverters in the U.S. and elsewhere were disabled from China, highlighting the risk of foreign influence over local electricity supplies and causing concern among government officials, three people familiar with the matter said.
Traditional “grid-following” inverters require an outside signal from the electrical grid to determine when the switching will occur in order to produce a sine wave that can be injected into the power grid. In these systems, the power from the grid provides a signal that the inverter tries to match.

The impact of rain on radio communication depends on the intensity and duration of rainfall. Heavy rain can cause severe signal degradation, particularly at higher frequencies. This phenomenon, known as rain fade, is a common challenge for satellite and microwave communication systems.
Wind, while not directly affecting radio waves, can impact radio communication by influencing the physical environment. Strong winds can cause antennas to sway or become misaligned, leading to signal instability. High winds can damage or topple antennas in extreme cases, causing complete signal loss.
The intense electrical discharge associated with lightning generates strong electromagnetic fields that can disrupt radio signals. Lightning can cause signal distortion, noise, and complete signal loss. The impact of lightning on radio communication is more pronounced at lower frequencies, making HF and VHF bands particularly susceptible.
Temperature is one of the primary weather factors affecting radio communication. Temperature variations can influence the density and composition of the atmosphere, impacting the propagation of radio waves. High temperatures can cause the atmosphere to expand, leading to changes in the refractive index.
