Growatt SPF-5000 ES with Daly BMS

[Koubiacz]

Hi,

I recently installed a LifePO4 16s battery pack at home as a back-up battery.
It's a home-made pack, I have a Growatt SPF-5000 ES inverter and a Daly 150A BMS with a CANBUS/RS connection. I had a small cable supplied.
I followed the instructions for connecting this cable to an RJ45 socket in the Growatt manual.
When I select the battery type on LI with the L004 protocol, the inverter goes into error. Error code 20.

I've checked my cable connections.
In the Android Smart BMS application, I selected Growatt and RS485.

I tested various solutions found on the internet (except firmware updates) but nothing worked.

I'm currently using the USER2 manual settings, but is there any way to make the inverter communicate with the BMS?

Thanks

Hi can you elaborate on how you have solved the problem? Im also using DALY with Growatt. Thank you.

Hi,

I bought the Daly interface card for Daly BMS.

You can find it on Aliexpress for example :
They call it parallel interface board


In the Growatt inverter, when you select Li (Menu 5), you choose protocol n°4.
Don't forget to configure the Smart Bms application to select "Growatt and RS485 protocol".

What port on the bms did you connect with the parallel board?
My daly has UART port only.
