🔋 Powerful Vertiv Liebert PSI5 1500VA Lithium-Ion UPS: Reliable 13500W 120V Mini Tower Line Interactive AVR with UPS Lithium Battery Backup - Single Phase (PSI5-1500MT120LI) Review

Very heavy despite its thin appearance. Arrived damaged, bent, main switch fell apart. Only $100 returned. Ask the seller to use the correct shipping service! Please pay attention to the AC input plug before purchase, it is NEMA L50-30P(R), if you plan to use in residential areas, you need an adapter. Do not connect to the dryer socket, it is 240 V! There may be an issue with proper cooling, for some reason a rear fan isn't installed at all.

I have several old Liebert UPSs with VRLA (gel cells) batteries, but they don't last long and never seem to have enough power when I need them for work. Just a day after installing this new lithium-ion pack, there was a momentary power outage of about 10-15 minutes and my computer and networking gear continued to run fine. I will never go back to lead acid batteries! Another nice feature is that the lithium block is noticeably lighter.

I installed this UPS in a rack, so far it works fine. I was expecting to be able to just plug it into my Linux system via USB and control it with NUT (Network UPS Tools). However, this UPS is not supported by NUT. Argh. If you're wondering, it uses a removable 48V 5Ah / 240Wh LiFePO battery. Big, but not that big: My €150 "solar generator" (which can also be used as a UPS in a pinch ) has a capacity of 333Wh. it's LiFePO if you're wondering) it will still be heavy. The AVR functions work, but…

I ordered a Vertiv Liebert PSI5 Lithium Ion UPS -1500VA/13500W 120V Mini Tower, the fan was noisy; very loud. The company sent replacements in a timely manner and it works as advertised. Thing is, it works so well I'd consider keeping both, but the noisy fan was unbearable. I returned the first tower about 3 weeks ago on 08/21/2021 and I haven't heard any news about my return. I have to say so far based on the performance of the UPS during multiple power outages; I tend to use the second device
