Technical Support

Hi everyone, can I please have some guidance, I'm fairly new to solar, I've had my system commissioned on 20 December 2020, and ever since I've had code F40 fault-battery overcurrent- 3 consecutive days then the other day then 3 consecutive day again ( I would really say almost every day), and the system switches off everytime the batteries are charged at 100%, then switches on after about 2 minutes. I'm battling with my installer🤦, is there anything I can do on my side, because from the little reading I've done, this might cause detrimental effect to the battery bank, whilst he's taking his sweet time to come check the system. I'm running off grid on a 5Kw sunsynk, 10,5 kW battery bank (3 x US3000 3.5 kw Pylontech lithium batteries) with 10x 360 mono panels.
