November 15, 20214 yr Hi All I need some advice. Recently I have had a Growatt 5000es inverter with a Narada 48NPFC100 battery fitted. Untill now the installer and myself has not been able to figure out the settings. I am unsure of the balk and float charge voltage setting and the communication protocol. MY thinking is if the battery has a BMS and communication port so does the inverter. There should be a way for the 2 to communicate. currently the Battery SOC and the inverter SOC does not correspond. is it possible to get the 2 communicating if so how? Your assistance will be highly appreciate. Regards Paul

November 10, 20223 yr Hello guys, Does anyone have any reliable settings for this setup that ensure a good battery life? The settings I am mostly interested in are the following: Setting voltage point back to utility source when selecting SBU (program 12) Setting voltage point back to battery mode when selecting “SBU priority” (program 13) C.V charging voltage (program 19) Floating charging voltage (program 20) Low DC cut-off voltage (program 21) Thank you in advance Regards, Wilson
