paulw Posted May 17, 2022 Posted May 17, 2022 Hi, Can someone please assist with the correct settings for 2x Pylontech US3000C bat with Sunsynk Inverter. Should it show both batteries details on the inverter or only the one as on the foto? Thanks for helping Quote
Nexuss Posted May 17, 2022 Posted May 17, 2022 (edited) Yup everything is looking like it should . Just untick the "BMS_Err_Stop" The Inverter is basically just seeing them both as one battery so yes you just see the one . Edited May 17, 2022 by Nexuss Pumba 1 Quote
Irocmaster Posted May 17, 2022 Posted May 17, 2022 See the address settings are all the same on batteries. hoohloc 1 Quote
paulw Posted May 17, 2022 Author Posted May 17, 2022 Isnt the adress settings there for RS485 connection and can doesnt really care? Quote
paulw Posted May 17, 2022 Author Posted May 17, 2022 Why should I disable the tick? Manual says toe tick? Any specific reason? Quote
Nexuss Posted May 17, 2022 Posted May 17, 2022 Address settings are only for when you have multiple groups of batteries AFAIK Quote

It doesnt really matter , the Sunsynk log wil just for some reason log lots of bms comms errors when its ticked. But it doesn't affect how the system performs for me. Pumba 1 Quote

He need to have one battery as a master and another one as slave. So the dip switches on the batteries will differ. Then/hopefully, he will see both batteries on your inverter instead of one Quote
