Hi. I have an Axpert VMIII 5KW and WatchPower v1.13SP3 working via an extended RS232 cable to a serial port card on a Windows 10 PC. I've tried upgrading to WatchPower v1.14SP8 (and 2 others) but I get no comms. The Com. port and Mobus settings are the same as the working v1.13. Anyone have any ideas please or a recommendation for a better monitoring software that works with the VMIII? Thanks, Trevor.

Hi. Thanks for this wonderful forum with a wealth of information. I have an Axpert VMIII 5KW with 2 X US3000 Pylontechs and 10 X 355W Canadian solar panels. I set the Max charging rate to 40A (2 X 20A per battery) as suggested by my supplier (and elsewhere) and after my solar panels were installed I changed the AC charging rate to 2A. However, the Max charging rate appears to be auto adjusting itself irrespective of whether I change it on the inverter or via Watchpower. I've seen the Charging current go as high as 53ish A at the 88% threshold late morning with the Max charging rate showing 70A even though I just changed it, then a little later with the battery at 100% the setting shows 20A or 10A even though I haven't changed it? Is this normal BMS behavior with the Battery type set to PYLON or is something weird going on here? Many thanks, Trevor.
