Hello
I'm new to the off-grid thing I've started the first purchases for my off-grid system this will mainly be used in my garage/workshop
The components so far are
- the solar panels
- victron MPPT100/35 smart
1 battery Liontron LifePO4 type LX48-50 - 50Ah/ 2.56KWh
The battery has a BMS on board that can communicate via CAN bus
Still to buy
- converter phoenix 48/3000
- To ask
do I have to use the CAN bus on the battery, if so what is needed
fuses
-40Amp between MPPT and the busbar for battery charging
according to victron's calculator we would get the following charging current
Max PV voltage@min temp=89.6V
Min PV voltage @max temp =55.8V
Max current@MPP min temp =30.9Amp
Max curren@Mpp max temp =24.5Amp
I provide the section of cables for this on 10mm² with a max length of 150cm
The cables supplied for mounting the battery on the busbar are 25mm² it is advisable to put a fuse between them - 50Amp or more?
Discharge current >50A(>5sec) or Discharge current >75A(100ms)
Short circuit current: >300A(>400µS)
between busbar and towards the inverter fuse 100A and possibly smart battery protect SBP 48/100?? and also a switch
3000W at 48V gives a current of 62.5Amp which I will rarely use
Any info to put me on the right track is most welcome
Sincerely
Peter
