I am a bit budget-strapped at the moment but would like to increase my battery bank. I have 2 x Pylontech US2000 plus 48v batteries and am considering adding another Pylontech 48v battery to the mix. Would this be a problem connecting these because they would not be equally balanced? Or would the individual BMS on each battery suffice to sort out these issues? I'm still new to solar so these answers don't come naturally to me (yet). Also what would the risk be in adding a different vendor of battery or different capacity battery?

My solar array is under-performing and I need to upgrade them. I am saving to do this now, but in the interim I need to be able to charge my batteries from a combination of PV and grid. Is this possible with my inverter? I see there is talk of a backup mode on the inverter but this seems to only charge from the grid and then use my PV and batteries as a backup to grid power only. This isn't really ideal and not what I am looking for. Is there perhaps a configuration on the PV Master app where I can redirect just some of the grid power into my batteries and still use my PV array for consumption and battery charging? Any guidance here would be appreciated. EDIT: i see I have double posted. My apologies for doing so Second edit: I wasn't aware that I could set Economical mode. What I have done is set the following in economical mode: Charge time start: 06:30 Charge end time: 19:00 Power limit: 50% To try to ensure that my PV powers my batteries and load during this time and my batteries aren't used. It will draw the difference from the grid Discharge time start: 16:00 Discharge time end: 06:50 So if there is loadshedding my batteries can be used if need be and we use the batteries during this time as much as possible (up to 50% of the inverter capacity) I hope this is correct and my interpretation is correct
