Hi Guys! I have a little issue with Axpert Max 8 with battery communications. The comm between inverter and batteries is ok /Lib/, but if i watch the inverter thru the app, there is showed every time 100% the SOC. Independently from the real charge/discharge amps/voltages. It shows 100% when it's fully charged or in the morning when it's around 40-50% discharged. If i check the history in the app there is randomly shows the real capacity, 96% ;80% etc but in the next history page it's 100% again and the battery voltage is the same. I checked the BMS but it seems works well. I have a four 5kwh battery pack (20kwh) and it seems that during the night them consumpting only from the 3 slave node the master is keep itself fully charged. But if i check the batteries real time thru it's BMS software during the discharging, all nodes discharging incl. the master node too. Is it normal or it has any issue with? Thanks Janos

Hi Guys! I have an axpert max 8kw with taico batteries 3 pcs 51.2v/100ah but when I connected them the axpert says low voltage “code 4”. The batteries are almost full. Any idea to solve this problem? The batteries see each other and the inverter works in lib mode. thanks Janos
