My BMV-700 is showing fuller capacity than the voltage suggests (possibly wrong as much as %30)
I need to know how to sync it properly.
My system is a 24v solar
Victron Easy solar 24/1600 inverter
2 x Rolls Batteries S12-290AGM 12V 260Ah (C20)
Victron Battery Monitor BMV-700
System has been in place for a year, I have noticed the BMV SOC is wrong over the past 2 months.
My sync parameters are as follows :
1.Battery capacity – 260 Ah
2.Charged Voltage – 29 V
3.Tail current – 4%
4.Charged detection time -10 minutes
5.Peukert exponent -1.25 (default)
6.charge exfficiancy factor – 95%-(default)
6. current threshold – 0.1 A (default)
question 1 ?are any the parameters needs changing ?
Possibly i need to sync the BMV again, my understanding was the unite sync itself by bringing it to %100 charge twice a month.
My question 2- can I sync it manually(using the buttons) any time or is the solar system need to be at a particular stage for syncing?
