max output from panels is 7.8kwH and we have about full sun from 8am-4:30pm for last couple of days so I think it should be fine?

Hi, I seem to be having an issue with my battery bank. I have 3x Pylontech UP5000 hooked up to 2x 5kwH SPF-5000ES and two strings of Solar panels, I seem to have an issue with the third pylontech battery (one on the bottom, furthest away from master battery) All Pylontech batteries are connected to each other and master battery is connected with BMS to my inverters. Every other day (more frequently during loadshedding) it seems my third battery goes into protection mode quite frequently and I'll have to turn it off and on again to get it talking again with the other two batteries. All batteries are grounded and connected properly to one another, any ideas as to what would be causing this?

Hi @Buyeye Thank you, I'm going to have look tonight to get a better idea, had a cloudy day yesterday so I will have a better idea hopefully by tomorrow, appreciate your input!

Hi everyone, I was wondering if anyone has experienced the following: I have 2xGrowatt inverters hooked up which is connected to 2x3.8 kWh strings of solar panels and they are feeding into 3x Pylontech UP5000 batteries Everything seems fine, the BMS communicating with the inverters properly the only issue that I can't seem to fix is that the inverters seem to be only charging the batteries to 50V and shows 100% on the inverters and the SOC on the batteries are showing 100% In the pylontech booklet it shows a max voltage of 53.5V and the settings on the inverter automatic got set to floating charge and charging point of 53.2V but the voltage keeps staying balanced on 50V on the inverter, if the voltage goes above 50V it starts discharging rapidly back to 50V so the capacity is really bad, for reference if the voltage drops to 49.3V the capacity on the inverter goes down to almost 60% and this seems unlikely as this should be at least 14.4 kWh with a max discharge of 95% Does anyone have any insights on what could be causing this?
