Growatt 3 phase smart meter

Hi, I am looking for as solution for my DIY solar system.
My current setup is using 1 phase hybrid inverter, supporting 48v battery. I am using 1 out of 3 phases in the house, since the inverter is 1 phase. I am living with that for over 2 years and have no problems. The main issue is that this inverter has only 1 mppt tracker, and I have two sets of solar panels facing 90 degrees from each-other, so I loose some power.

While I look for a 2x mppt capable inverter, I am also considering that it would be nice to move back to 3 phases.

My friend has Growatt SPH 3600 and Growatt 3 phase Smart Meter. He says it is able to convert 3600 one phase to 3. I have some doubts about that, so want to confirm before hunting for this now rare SPH 3600. Sph 3600 supports 48v custom battery, it has 2 mppt trackers.

Firstly I would like to know if Growatts' smart meter can convert 1 phase inverter to 3 phases?

And if anyone knows a decent priced solar inverter that is:
* a hybrid with 48v battery, not requiring BMS communication
* 3 phase
* 2x mppt
?

Thank you.
