This inverter is able to pump out some serious power and it’s easy to set up since you can connect it directly to a single battery or multiple for more juice. We’ve had some power outages here recently so I was able to use it to hook up my network rack, that way we still had the internet while we waited. While that was only pulling about 100w or so the fan on this was pretty loud. I contacted support so see what was going on since once you pass a certain wattage the fans on this kicks on and is way louder than you would expect it to be especially since you aren’t anywhere near its rated capacity. They did mention that they were working on reducing the noise so hopefully they come out with something that is way quieter that can match its all in one solar generator competitors like the new ecoflow line that is dead silent. While this isn't advertised as being able to be used as a UPS since it doesn't have a connection to mains you can still use it as a double conversion ups by having power feeding into your batteries and then this connected and feeding your device. This only works though as long as your draw is less than what the 1/3 chargers can provide though and will put more wear on your batteries than a traditional UPS that does mains pass through most of the time. If they do release a way to reduce the noise I will update this to be 5 stars since the noise is the only thing bothering me.
