Hi
I'm going to be adding a 48v 280AH battery to my existing 48v 304AH battery storage. Currently the 304AH battery pack has a JBD bms which is doing it's job, keeping the cells safe. It does not have any communication to my inverters (2P SPF5000ES), the inverters know when to disconnect the battery based on voltage they see on the conductors going to the battery.
I've seen some posts here on the forum of guys and gals using a Seplos BMS so that the battery pack can communicate with the inverter to report SOC, while I think that's pretty neat .. what does it really add ? The inverters know based upon voltage when to charge or discharge.
I'll have a 304 nd a 280AH, unmatched capacity, . does two Seplos BMS's make sense here because they will be able to talk to each other ?
And what's the use of that screen they sell with the BMS? I see that as extra wiring and complexity to mount the screen which will never be seen since the packs are in a crawlspace.
Would really appreciate any input.
