Just ordered 32 EVE 304Ah cells for my whole-home system I am working on. I've done a considerable amount of research into battery construction and BMS, but I still can't figure out what the best solution for my situation would be as far as constructing this battery bank. I want to be able to supply 200A continuous from the battery bank.
So my understanding is there's basically two ways to set up a battery bank: closed loop and open loop; closed loop means the inverter is communicating with the battery bank, and open loop means it is not. Closed loop it seems tends to be a lot more complicated.
As stated in the title, I have a SolArk 15k inverter on order which will be AC coupled to my utility connection. I contacted SolArks technical support to ask about this, and they told me the only 'officially' supported BMS for DIY batteries is the Orion series. Seplos (saw this in another thread) says that they can emulate the CAN message protocol for a few different battery manufacturers (such as Pylontech, which SolArk has a configuration for), so that also may be an option.
The other option I was looking at was to parallel two Overkill 16s BMS as opposed to building a single 16s2p bank.
So at this point I'm left with a few questions that my research hasn't really answered:
- In this scenario what (if any) would be the tangible benefits of closed loop over open loop?
- If I go the closed loop route, with say the Orion, what other components (if any) would/should I include in my battery build?
- In general, aside from a BMS what components are generally recommended for a good build (disconnect switches, monitoring shunts, etc.)?
Appreciate any insight that y'all can provide me.
