Have 3 questions with regards to RCT-AXPERT 3K-48V inverter.

1. Does anyone know if RCT-AXPERT 3K-48V is compatible with pylontech us3000? I seem to find info stating us2000 compatibility only.

2. I assume that we can use ths inverter in backup mode with no panels? If this is correct are the changes made on the buttons on  the inverter?

3.  Does the inverter come with a monitoring tool to monitor battery and load usage? if not what are the options available.

Looking forward to feedabck.

If it works with the US2000, then it will also work with the US3000, just with slightly different settings (higher maximum charge current, setting 02).

Yes. Of course, you're then wasting a part of your investment (the solar charge controller).

You can make settings changes using the buttons or the provided WatchPower application, or other monitoring software.

As indicated above, it comes with an old version of WatchPower, or you can get the latest version here.

WatchPower isn't all that satisfying, so often people use a product called ICC, running on a Raspberry Pi. Other possibilities include LUCIBUS and SolPipLog. I have no idea if these latter support your inverter; almost certainly ICC does.

Thanks Coulomb. Appreciated.
