How long would I spend to establish a simple OpenEMS system if I'm a newer for this project?

Hey,
I am trying to get live and history data which is from the battery and inverter used RC485 or CAN in the OpenEMS UI Energymonitor screen view. I wonder how long it would take if I work by myself. And in the near future, there’s going to analysis error and send signal to controll machines. Does it work on Open EMS System?
Thank you.
