Hello all, I downloaded software called MultiSIB. It works very well with my 5kW Mecer Axpert inverter. I have an old laptop connected to it permanently. (Better than throwing it in the e-waste bin). I dial in using Teamviewer on my phone from anywhere. I can change settings on the fly as loadshedding changes. I don't know if the software is still supported but it doesn't matter, it works on the old machine running Windows 7.

@ErichK you could also connect Pylontech batteries. A lot of detail each cell , battery is displayed. Use the same cable as ICC or Solarassistant. There was a software up grade about a month ago. I use Solarassistant . When I want to see detail off battery cell MultiSIB is handy.
