I have this in my house, but it does not provide what a UPS does. I have 42kwh of Enphase batteries as well as 53 solar panels (20kw) with enphase microinverters, and the battery system is inline with the incoming power. If we lose power the batteries kick in, however the time for them to kick is in >100ms. Computers will reboot with that timeframe of power drop. In my case I use a 16kw APC Symmetry UPS (which is datacenter UPS) for the interconnetion to my dataroom. The UPS provides double on-line conversion as well as battery backup. However the batteries in the UPS are only large enough to provide for about 30 mins of runtime at my current sustained power rate (~6kw) My goal with the UPS is to have both the inline conversion protection as well as the protection from power drops. As the author mentioned, UPSes do suck, and the Symmetra I have does as well. I have replaced 3 power modules (which are about $1k each), one network module, and all of the batteries. And it has an alarm right now about one of the battery banks being bad. ;) (For those interested, there is a bit more detail about my power system in a garage build thread: https://www.garagejournal.com/forum/threads/jeffs-mountain-side-shop-portland.409988/ https://www.garagejournal.com/forum/threads/jeffs-mountain-s...)
