I have a growatt spf 5000 es off grid inverter which I’m trying to communicate through BMS port with felicity lifepo4 lithium battery 170 ah 48 v.
tried the protocol send by the supplier which is program 5 (battery type Lithium ) then in 36 I used PTCL L04 without success (I get fault 20 which is communication error), even updated the battery to newer latest version 307 still the same error, any idea on what settings should I use ?
i’m a newbie in this field and appreciate all help, thanks.
