The end is nigh...
One of the last available 4th generation 120v products has finally been discontinued, the SUA3000RMXL3U (my sku 333b) and the SMX3000RMLV2U was released in its place.
Instead calling them the 5th Generation or "V", like I call them, APC and vendors have settled on Smart UPS X.
Comparing the 2 models, we see that APC has managed to improve runtimes with a new battery pack in a 2U frame. It has also dropped the surge suppression rating, increased the warranty to 3 years, and dropped the BTU footprint. Learn more about the 5th Gen / Smart X here
Additionally, APC has left the 48 volt DC architecture and gone to 120volt. DC. This will allow those upgrading to be forced into pitching their existing 48v battery packs for the new 120volt system.
While, I dont anticipate getting too many of these in yet, when they do arrive, it will be designated 312v
