I have been a very long-time user of Cyberpower UPS units, but long wanted to switch to a lithium chemistry based system for the increased power density and run time.
The TLDR is that I want a solar generator that: 1) can output 1500+ watts; 2) has a reliable 10-20ms UPS-like transfer when the power goes out or the home voltage drops to around 115v; 3) is absolutely silent when in AC pass-through on wall power; 4) properly operate in a room with a noise ceiling of 25db with all noise making objects measured at a distance of under three inches (7.62 cm) from the objects; and 5) just to be clear not make any noise while acting as a still-plugged in UPS.
Back in the summer of 2022, I was looking for lithium battery info on youtube to have a small battery backup for the hurricane season that would last powering my kitchen fridge and possibly a one-room portable AC during a power failure until it was safe to fire up a portable gas generator. At the time, I was impressed by the Vigorpool Captain 1200 for being able to put the inverters in parallel so as to power any portable cooking appliance and readily fire up a medium-office scale laser printer... so I ordered a pair along with the parallel cable.
Although the Vigorpool units performed exactly as advertised, including having a great UPS transfer and load splitting when in parallel operation, I ended up being unable to replace my aging rackmount Cyberpower UPS because the Captain 1200s while in AC pass-through mode are not truly pass-through and the obscenely, obnoxiously loud fans frequently spin up even when the units are on standby with temperature readings of under 20C! Rather than real pass through like most old-fashioned lead acid based UPS companies, power trickles into and out of the Captain 1200's batteries while the inverter is on and that is almost constantly setting off their fans.
Because of that, I went back to using my rackmount Cyberpower system since it makes no noise unless and until the power goes out or voltage drops (because the county water company has pumps in the neighborhood that don't play nice with FPL's power lines). Unfortunately, and after "only" nine years of service, one of the batteries in the Cyberpower system has died.
I need truly quiet system while still receiving regular wall outlet 120v power. Making appropriate noise is fine when the power goes out, but in all other circumstance silence is vital.
Would like recommendations for any portable-ish all-in-one that fits my use requirements or alternatively battery / inverter / rectifier parts list that will also cover my silent UPS needs without being reliant on bluetooth or Wifi to work.
