Hi guys, I have a strong background in electronics, but pretty new to Lithium battery technology - especially BMS systems and CAN system link ups. I am about to set up a Sunsynk inverter system in a week or so - and an installer has suggested these Vision/Mecer Lithiums as a 10kW battery option - 4 x 12V 200Amp items in series.
My question is - with the built in BMS system in the batteries - am I correct in understanding that there will be no physical BMS connecting data cable to the inverter - other than the charging / load cables?
The inverter has a pretty decent BMS built in - but worried about how well the inverter can estimate the SOC of this battery bank? will it do so on the voltage/current flow alone?
Thanks
Lyndon
