How would I find that out?

This is what I have - https://www.pinnacle.co.za/proline-upsi2000rt-2000va-on-line-ups-rackkit-inc

Inside where 4x 12V, 45W/Cell, 10min batteries

Can you take a picture of the battery wiring? It can either be 24V or 48V. Does it have an extra port for an external battery?

Here's another, we used to have some Weable guy on the forum, not sure if they are still here.

W-POWER BOX | 3KVA/3000W AXPERT VM3 OFF-GRID PURE SINEWAVE INVERTER | 2 X 12V 120AH LITHIUM ION (LiFePo) BATTERY | 3KW USABLE ENERGY | BLUETOOTH BMS

Still here service advisor for them on solar related. Depending on what the customer is looking for and budget needs. @PhreakBoy you can drop me a shout and I can put together something for you.

Just to touch lightly on the C rating. Pylontech US3000 batteries do make use of 1C rated cells but pylons warranty limits its to 0.5C to give you an extended life from the batteries.
Off-Grid inverters just mean that it will be unable to interact with the grid and send power back to the grid. Blending of grid and Solar is usually done on the DC end of things with majority of Voltronic Inverters.

Pylontech US3000 batteries do make use of 1C rated cells

AFAIK, the US3000 cells are rated at 3C, but I guess it's possible that they use different cells to meet production volume.

For the ones with the 37ah cells they are rated at 1C but on testing they can test up to 4C for various tests to ensure that the battery will survive use and its cycle life is on par with their 6000 cycle count. Got a few of the US3000s sitting on the office floor with dead BMS's but all of them are making use of the 37Ah cells.

Running a similar setup at home, (just a home made battery)

Runs everything except the kitchen and geyser. Kids and wife are happy with it, which means I am happy

Honey, now that you have sorted out this little thing, what about other 300 other things I need to remind you all the time? When are you going to fix them?

I can neither confirm nor deny that it seems too familiar.

I have the same kit in a portable Addis tote/tub on wheels, but with S-120's. Batteries and inverter in the tub with plenty of holes in the sides. Very happy.

So I'm not the only one hating the constant high rpm fans on this specific unit. I bought a fan speed controller, but I need to mod the fan connector, and order a second one when the supplier has stock again. No heating issues inside the tote bin? I have mine in the garage, wall mounted, with the door closed, I can still hear the fans, drives me a bit mental, sounds like white noise

Inverter does it all. Plug and play.

Show how its sitting inside the box with battery?
