I Downloaded the Yaml code from Github and setup 2 Growatts GBLi5001 batteries in parallel
Original Concept has RS485 connection , but as the code was not ready i did without it
and this is the result in working:
Made both settings in the JKBMS JK2a24s15p similar
# Operating Voltage
46v (3.28) to 57v (4.07)
# JK-Can
Absorption Voltage
Absorption Offset - 0.05
Absorbtion Time - 42 mins
Bulk Voltage - 55.7
Rebulk Offset - 0.8
Float Voltage - 54.1 change to 55.9
Discharge Current - 40 A
Charge Current - 40 A
Total Battery Capacity - 95 Ah
SOC 100% 4.0
SOC 0% 3.25 NEW 3.34
UVP 3.33
# JK-Can-2
Absorption Voltage
Absorption Offset - 0.15
Absorbtion Time - 42 mins
Bulk Voltage - 56.4
ReBulk Voltage - 53.6
Rebulk Offset - 0.8
Float Voltage - 56.4
Discharge Current - 28 A
Charge Current - 40 A
Total Battery Capacity - 95 Ah
SOC 100% 4.0
SOC 0% 3.25 NEW 3.34
UVP 3.33
BMS protection settings
Version
Same BMS Model but mismatched from JK
Physical GBLI wiring
Testing phase
Testing voltage from Pin 1 to 14
Testing for voltage and resistivity
the voltage when BMS was turn on
GND <-> RX 3,31V
GND <-> TX 3,32V
GND <-> VBAT50,21V
the resistance when BMS was turn on
GND <-> RX 95,48 ohm
GND <-> TX 0,00 ohm
the resistance when BMS was turn off
GND <-> RX 6,19 kohm
GND <-> TX 3,11 Mohm
Please measure the voltage between
GND <-> RX
GND <-> TX
GND <-> VBAT
Please measure the resistance between
GND <-> RX
GND <-> TX
Growatt data sheet used
Solis End
CAN Port from BMS to Inverter
Ignore 2/6 connection
