February 5, 20215 yr Please if anyone can assit. I have Axpert 5Kva connected via BMS unit to Pylontech.. Only change made on Axpert is to change batt type to User.. I am not sure what rest must be. My issue is on Axpert battery shows full but on Pylontech it seems to charge constantly second last light flickering and first light off (Charge indicator). Indicating battery never full. How do i get it to charge fully and sync the two. Any assitance is appreciated. Thanks

Most ones cannot talk to the BMS directly - so you probably need to manually set the charging parameters (52.2V Bulk and 51.8V Float) as well as the other voltage settings (Back to Grid, Back to Battery, Low DC Cutoff) If your Axpert cannot talk directly with the Pylon BMS, I would strongly recommend ICC to be able to switch the Axpert based on the accurate BMS info instead of the Axpert's voltage readings

Has it been proven that 52.2v is sufficient? Maybe i missed the memo. lol

February 7, 20215 yr With ICC or SolarAssistant you will basically ignore the inverter state of charge and just look at what the app reports. It won't solve the charging issue, that should be charge voltage settings as mentioned. It will solve switching between battery/grid: https://solar-assistant.io/help/power_management/axpert
