Where are most US based inverters manufactured? If someone is off grid or hybrid, what is the concern, outside of power-feedback into the grid? This seems more like an admission that going off-grid or hybrid is becoming attractive enough to matter. It's already not up to code to connect a non-UL listed inverter to the grid.
Real, actual concerns:
-Lack of security
-Password defaults left on device during setup
-Aluminum transformers in inverters don't last more than 4-5 years at rated wattage
Largely because there are radios in the inverters. Typical connected-grid stuff is sending people with too little knowledge into a tizy
Actually a security researcher found a back door in some Chinese inverters recently.
Normally I’d believe this administration is just knee-jerk banning because China and solar, but in this case there was an actual reason.
Would appreciate a non-paywalled source.
As for the subject... I generally don't have a problem with this. Handing over any part of your energy infrastructure to a country with a long and storied history of hacking your companies is generally not smart.
I've purchased two inverters: one is a 3000w "Energizer"-branded one, while the other is a 1200w Victron unit. The Victron's quieter on RF, from what I can tell, is designed in the Netherlands, and is made in India.
