Are there any experiences and suggestions how to integrate/use Deye DEYE AI-W51 lifepo4 batteries with Victron?

Victron with Deye DEYE AI-W5.1
That is a question for Deye.
They are an unsupported brand, in the absence of comms, it would require a shunt and old fashioned voltage control. Rather buy a supported battery, plenty of official and third party variants.
So what supported battery do you then recommend:
My requirements:
- IP 65
- Temp Range -20 to about 50°
- 50 kwh (expandable)
- 48 V System
- built in extinguishing device would be nice
If Deye batteries fullfill all these requirements, why not looking for a Deye inverter, that fits to these batteries?
because in combination/co-existence with a (bigger) grid connected inverter, there´s a painfull feed-in limit configured in all Deye inverter
by example, the sun5klp1 stops poduction when overall feed-in exceeds 5500W and battery SoC 100%
with a second grid connected 15kW inverter also used for AC loading, this limit sucks and stops Deye PV production before lunch (for 4-6h every summer day)
waiting for a firmware update since last year, tried with several Deye support contacts. no success
