HI all,
I am having an issue with my off grid power system, the company i bought it from are struggling to work out what is wrong.
I have 6 x plyontech batteries with a Victron Quattro 15kva inverter & 2 solar controllers. Initially system was perfect but lately it will email me constant errors, lost bms and low battery. Batteries are always close to full as I’m not living there yet just getting used as construction power. We thought it may be the invertor playing up so they have replaced it with a new quattro , it was perfect for 2 weeks and then the issues have now come back. Have anyone else had this, is it the batteries bms or the solar controllers. Getting very annoying now.
Thanks
