So i have a growatt spf5000tl-hvm and 2 growatt hope3.3l-c1 batteries...but when i select Li in setting 5 it takes me to a bms protocol setting which you dont find anywhere....does anyone have an idea which protocol to select

Hi Romeo,

Please see attached setup instructions, 

I have the same batteries and a Growatt inverter, not very happy with the batteries as the keep giving allot of issues with coms and the system turning off completely at random times. What is your experience?

Hello.

Came accross the below link showing the Lithium protocols to set ( Growatt ) for various lithium battery brands.

Please give update an how well the growatt communicates with the battery as a friend has an 5kw growatt and am-2  51v 5.5kw Hubble battery on protocol 52

In the beginning everything worked great but after 2 week it would not charge passed 92% and getting worse so we set battery type to  user and run it from volts for 2 days to calibrate the setup , after 2 month the battery was not last longer than an hour of load shedding but was showing 99% full when charged but volts were 44v so battery was flat . 

Best solution was to disconnect the communication cable and change battery setting to use and run it from volts only . Working great .

He want to get anothere battery but if there is issues with Hubble growatt compatibility it's not worth buying anothere Hubble . 

it will be nice if your combination works  

But it sound as if there is also issue with that combination from Jorams post
