Are Chinese solar power inverters connected to critical infrastructure grids?
U.S. energy officials have launched an investigation after discovering unauthorized communication equipment embedded within Chinese-manufactured solar power inverters connected to critical infrastructure grids across the country.
Could cellular radios be used remotely to switch off power inverters?
The rogue devices, including cellular radios, were discovered in Chinese-made power inverters that are used to connect solar panels and wind turbines to electricity grids across the world, including the UK. The hidden communications equipment could be deployed remotely to switch off inverters with potentially catastrophic results.
Do solar inverters contain undocumented cellular radio devices?
These inverters, which are essential components that convert direct current from solar panels into alternating current usable by the electrical grid, were found to contain undocumented cellular radio devices not disclosed in product specifications or technical documentation.
Why were solar power inverters disabled from China?
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.

How do inverters provide grid services?
In order to provide grid services, inverters need to have sources of power that they can control. This could be either generation, such as a solar panel that is currently producing electricity, or storage, like a battery system that can be used to provide power that was previously stored.
Solar power in Hungary has been rapidly advancing due to government support and declining system prices. By the end of 2023 had just over 5.8 GW of capacity, a massive increase from a decade prior. Solar power accounted for 24.8% of the country's electricity generation in 2024, up from less than 0.1% in 2010.

How much solar energy does Hungary produce?
Data from transmission system operator MAVIR shows that solar energy production in Hungary reached a new peak on June 13, producing enough energy to serve the country's domestic electricity requirements entirely from renewables. Hungary has deployed almost 8 GW of solar capacity, according to the country's deputy minister of energy, Gàbor Czepek.
What renewable sources are used in Hungary?
Another renewable source utilized in large amounts in Hungary is biomass. The NECP proposes a significant increase in solar PV capacity but no increase in wind power capacity. Wind power capacity expansion has been blocked by the government for more than ten years, a ban that is without reasonable geographic or economic reasoning [ 8, 9 ].
Should the Hungarian energy transition be based on wind and solar resources?
Wind and solar resources should receive more attention in the planning of the Hungarian energy transition. However, the expansion of these vRES needs to happen simultaneously with the restructuring of the whole system [ 27 ].
How is the Hungarian energy system derived?
The input data to the model is derived mainly from national energy balance and other freely available databases which makes the approach easy to adapt and replicate. The following conclusions and recommendations are relevant to the Hungarian energy system.
The Solar Microinverter Reference Design is a single stage, grid-connected, solar PV microinverter. This con-version is done by an interleaved flyback converter. Each system unit operates with only tens of volts of DC voltage and is connected in parallel, which minimizes potential safety hazards. Renesas provides high-performance MCU alongside all. . There are two main requirements for solar inverter systems: harvest available energy from the PV panel and inject a sinusoidal current into the grid in phase with the grid voltage. The design is associated to the STEVAL-ISV003V1 demonstration board which demonstrates the possibility of implementing a full microinverter. . Designed for various industrial applications—including central inverters, single-phase string inverters, and modular micro inverters—this grid-tied solar micro-inverter solution provides a robust, adaptable platform for advancing solar energy systems worldwide.

Variable Renewable Energy Sources (vRES, solar PV and wind)1 capacity in Latvia has grown from 100 MW in 2022 to over 420 MW in 2024 (Figure 1). The huge interest from vRES developers during last years and growth in vRES capacities in Latvia is expected to continue as well as their technical impact. . An inverter is one of the most important pieces of equipment in a solar energy system. It's a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid uses. The on-site installation is undertaken by the Off-Grid Installer team and after all clients are included in the online remote monitoring service.
