Technical FAQs 4

Where are Huawei inverters used?

Their products are used in more than 170 countries, by over three billion people. Huawei inverters are used at the world's largest single PV plant, tracking system PV plant and rooftop-mounted PV plant. Huawei’s parent company is Huawei Investment & Holding.

What are hidden communication devices in solar energy equipment?

U.S. energy officials have discovered hidden communication devices in solar energy equipment supplied from China. These are primarily inverters used to connect solar panels and wind turbines to power grids, as well as batteries, heat pumps, and chargers for electric vehicles.

Are there undocumented communication devices in solar panels?

Over the past 9 months, undocumented communication devices (including cellular radios) have also been found in solar panels from several Chinese suppliers. The exact number of inverters and batteries tested, as well as the names of the suppliers, were not provided by the source.

Do Chinese inverters have a firewall?

Although the inverters are designed to allow remote access for updates and maintenance, utilities using Chinese versions usually use firewalls to prevent direct communication with the country.
