I have 5kw solar system & recently acquired 48v-200ah Lithium ion battery bank (consists on Sony 3.7v cells). It doesnt have BMS communication port. Battery bank have BMS & mobiel app for manage or monitor.
Since I have no support from official provider, I would appreciate if some one could guide me settings for BMS & inverter parameters.

Currently on inverter I have setup below battery parameters that I changed for this bank:

  1. CCV: 54.2 v
  2. FCV: 54.2 v
  3. Cutoff: 41.0 v (point where inverter will cutoff battery usage )
  4. Recharge: 45.0 v (point till inverter will use/discharge battery power)
  5. Re-Dischage: 50.0 v (point where inverter will using battery if solar/utility is not present)
& below are the BMS application (i have not changed any thing in it yet)

You should be able to find online the charging parameters for the Sony Lithium-polymer cells.
Then check those BMS settings
