Hello, looking for ideas on optimal settings for Victron Multiplus 3000 12v using victronconnect (or is using vedirect better?) with the Chins 300ah lifepo4 battery and charging/using 30 amp shore.
To start this is all the battery specs I could find on it specifically:
Chins 300ah LiFePO4:
Rated Capacity (0.2C): 300Ah / 3840Wh
Cycle life: 2000+ cycles at 80% discharge depth
Rated voltage: 12.8V
Charge voltage: 14.2 - 14.6V
Depth of Discharge (DoD): 100%
Standard charge current: 60A
Charging time: Approximately 6 hours
Max continuous charge current: 100A
Max continuous discharge current: 200A
Peak discharge current: 600A (Duration: less than 3 seconds)
Operating temperatures: Charge 0°C~50°C(32°F~122°F),
Discharge -20°C~60°C(-4°F~140°F), Storage -20°C~50°C(-4°F~122°F)
Impedance: ≤ 15mΩ
Starting from the top here is all the options I can find in Vconnect using mk3 (is there more?)
General:
1. Frequency
60hz
(no brainer)
2. ac1 input current limit
30A
(if I were to plug in a regular wall socket should I change this to 20 amp?)
3. dynamic current limit
(not sure the best practice)
4. Enable battery monitor on/off
(I have bmv712 so I need this on or off?)
5. battery capacity
300ah
(this seems straight forward I think)
6. state of charge when bulk finished
85%
(not sure what this should be)
7. charge efficiency
1%
(not sure what this should be)
Grid:
1. Accept wide input freq range (45-65hz)
on/off
(not sure what this should be)
2. UPS function
on /off
(not sure what this should be)
3. ac low voltage disconnect: 90v
(not sure what this should be)
4. ac low voltage connect: 97v
(not sure what this should be)
5. ac high voltage connect: 135v
(not sure what this should be)
6. ac high voltage disconnect
140v
(not sure what this should be)
Inverter:
1. inverter output voltage: 120v
2. ground relay: on
3. dc input low-shutdown: 9.30v
(not sure what this should be)
4. dc input low restart: 10.90v
(not sure what this should be)
5. dc input low pre-alarm: 10.90v
(not sure what this should be)
6. low soc shutdown: disabled
(not sure what this should be)
7. AES: off
8. power assist: on
9. assist current boost factor: 2.0
(not sure what this should be)
Charger:
1. charge current: 90a
(not sure what this should be)
2. absorption voltage: 14.60v
(not sure what this should be)
3. float voltage: 13.80v
(not sure what this should be)
4. repeated absorption interval: 7.00d
(not sure what this should be)
5. repeated absorption time: 1.00h
(not sure what this should be)
6. absorption time: 8h
(not sure what this should be)
7. charge curve: fixed
(not sure what this should be)
8. Lithium batteries: on
9. use equalization: off
10. weak ac input: off
(not sure what this should be)
11. stop after excessive bulk: on
AC input control:
1. conditional ac input connection: off
(not sure what this should be)
2. ac input connect based on load: off
(not sure what this should be)
3. connect when soc drops below: off
4. connect when battery voltage drops below: off
5. disconnect ac input on: battery voltage
6. disconnect when voltage is higher than 16v
7. delay before disconnection: 0w
Thanks!
