Daly Bms from China had added a new features to there bms's
You can set a minimum discharge and a maximum charge voltage to your liking, how are your thoughts about daly now?
No i am not affiliated, just curious.....

And how to calculate those bms's?
48v x 200A = 10KWatts an hour at 230v?????
I am doing something wrong, i am sure

You would normally go based off nominal voltage, which would be more around 52-54V. If it can do 200A continuous, then that'd be:

52*200 = 10400 watts
If you convert that to 230V, then throughput amps would be:
10400 / 230 = 45A

So it really would be up to the inverter if it can handle that throughput from DC->AC

However, if the top voltage is 60V, then at the absolute max @ 200A would be 12kW, or 52A on 230VAC. Pretty beefy if it can continuously output that current.
I haven't been keeping up with Daly BMS through its development, so not sure of the claims vs actual values

That's why I hang around here all day. After two years of no BMS and my battery builds probably stinking up the DIY Battery community, I am finally convinced that a BMS is needed. I'll follow the instructions and install this weekend. 60 amp way to big but I'm thinking when I expand.

That is a lot of power.
Looking into the future there will be more inverters on the same bms. and of course a bigger battery bank.
Our fuses are 16A at 230v ac, one will be enough to power our whole house.
Thanks

Daly are popular for e-bike and scooter builds, and we generally tell customers to oversize the BMS a bit. Would definitely recommend installing the BMS vertically and free of obstructions to allow sufficient airflow. Their 300+ amp boards even have forced-air cooling. One thing to keep in mind is that their balance current is 30mA regardless of size, which is essentially useless on a bigger pack.

We have contacts with their sales and tech teams in case you have any specific questions.
