Seplos advice needed
Hi Sunsynk setup working well....however the battery is giving me some issues have a 16S Seplos BMS 200a my battery has a theroretical capacity of around 15kw using 302amp cells. Communication is good no issues there. However...I have been running out of power over night...the battery gets down to around 35% state of charge and then plummets to 10% then grid charging kicks in.............. I then checked the Sunsynk battery charge and discharge history............basically it is charging up around 5kw and discharging 5kw....... ie around 100amps.... So I went into the Seplos BMS and found the following....
So - it appears to me that I have inadvertanly set SOC to 100 (thinking it was percent) ... underneath it says Ah ...... so should this parameter be set to 302???? can anyone advise...
I have 2x Seplos with 280Ah batteries and one of them had an issue where it wouldn't let me change from 200Ah to 280Ah. I had to resort to creating a rs485 to usb cable (picked up £9 adapter from Amazon) and using their windows software
