Growatt SPF 5000Es and felicity solar 5kw battery.

[JOVO]

Hello, to all participants. I make it short and will ask if a user can provide a decent battery setup for felicity solar batteries on growatt spf 5000es .
I can imagine that these information is available here , but i am lazy and already stressed out reading 100 of pages though.
(Is it possible to make a sticky post that contains such info? )
I am looking for max charging voltage, max drain voltage, and other relevant stuff. I was reading some posts and found all values are different, even felicity solar page differs.
I am planing to go online soon, but dont want to srew my hardware.
Thanks in advance..

Why don't you ask Felicity to share the guidance? Don't battery sellers basically provide customers with detailed setting parameters for inverter work?

Do yourself a favor and download the data sheet and user manual and ideally you would also download instructions covering connectivity of your specific inverter to your battery. It is all there. Read it and understand it. I did and the only thing that helped me when I ran into trouble ("LI" setting was crashing the inverter) was that I actually re-read the instructions and then I made BMS cable as per instructions. Correct BMS cable is a must with "LI" settings on inverter that allows communication with the battery.

Once I figured out the cable pinouts and made cable as per instructions both inverter and battery communicated just fine and there was no need to setup any parameters that you have mentioned.

And, I did initially setup the parameters manually on growatt inverter using "USER2" program because "LI" settings were crashing the inverter. If you want to go "USER2" route then verify what is the max voltage of felicity battery and set that as bulk, absorption and float as LPF batteries do not use separate voltages for bulk, absorption and float. BTW, on growatt inverter "USER" is for AGM/VRLA/SLA battery type and "USER2" is for custom LI battery type.
