I talked to an EG4 engineer on the phone about 9 months ago for my system design. I was going to use three Flexboss21s, six indoor 280Ah batteries, 30KW of solar and the generator input. I was not going to use Gridboss at the time. The engineer said everything was fine, but I should not use shared batteries because of a feature I needed. He recommended dedicating two batteries to each Flexboss. He gave me the reason, but I do not remember what it was. My system just got installed with a Gridboss. The installer configured the system with the six batteries shared across all three inverters. What is the feature difference between shared and dedicated batteries? What do you recomend?
