Powershare Question - Existing Generac Solar/Battery system & a universal charger already installed

[ConcreteTilt]

In 2021 - I installed a system that included solar panels with 2 Generac backup batteries. I had already installed a universal charger as well. Curious if anyone knows if the powershare gateway is the only thing needed at this point, or if the system would potentially work on the existing gateway already building into the home backup system?
