Hello All
Been reading your posts with interest . I believe the reason you are seeing low charge rates is due to the Inverter reading the bms default settings for charge rate amps as set by pylon . I have the original pylon extra 2000 batteries , and by using the pylon console program "batteryview " its clear to see these defaults , they can be user modified ( at your risk) . take a look at the pdf attached . Hope this helps
