Running a UPS off a inverter is just dumb. Also, none of the companies you list are big names in inverters. It would effectively be plugging a UPS into another UPS.Well from what i read here
Solution: Hi Kelvin,I am very sorry; unfortunately, we would not recommend plugging a UPS into an inverter. If the inverter is not outputting a pure sine wave,community.spiceworks.com
Apparently i'm gonna need a pure sinewave inverters otherwise the UPS won't accept the power,
there are alot of inverters in my local shop but none from the big names, e.g APC, cyberpower
Cyberpower do have some power inverters, but it maxed out at 1320 watt, not sure if thats enough for me.
Did you not read my response at all?
Your UPS is an inverter. Your UPS is an inverter. Did I mention your UPS is an inverter?
Additionally, the pure-sine requirement is not going to be general. Some UPSes may work fine, some may not, it depends on their internals. There's likely no way to know without testing.
Did I mention there's an inverter in hour UPS? Because there's an inverter in your UPS. Did you know there's an inverter in the UPS you have? Why not just use the inverter that's already in your UPS and rated for the load you have and add more batteries?
Like, that's literally why EBMs exist. So you can arbitrarily extend the runtime of the UPS's inverter.
