The US’s sudden ban on foreign-made power inverters, which are often used in solar panels, is raising questions about how long they will continue to receive software updates. The agency imposed a similar ban and software update deadline on foreign-made drones and Wi-Fi routers earlier this year. The inverter ban, meanwhile, also ensnares robot vacuums. Although the FCC is allowing minor software updates for power inverters, more significant software changes or hardware alterations are blocked under the current order. In addition, 90% of the inverters for the US solar market over the past 10 years were imported.
