Hello,
I am planning a Victron ESS with the following components
- Multiplus 2 48V / 5000 (only one in a 3-phase-system)
- Cerbo
- Touch 50
- MPPT RS 450/200 (all 4 PV inputs connected to solar modules)
- EM24
- home made 23kWh LiFePo4 battery with SEPLOS BMS
- grid parallel topology (only one phase connected to L1)
I have the following questions:
1) I EM24 ethernet or RS485 version ?
In my special case I have a long distance (20m) between the EM24 and the Cerbo GX.
Which one (ethernet or rs485) do I need ? Are both OK ? If I use the RS485 version, I understand it is connected to the cerbo with a USB/RS485 converter ? Is this correct ? And is this USB/RS485 converter included when I order the EM24 ?
2) Which cables do I need for interconnections, I am confused about VE BUS, VE CAN , VE Direct ?
So which cable do I need
- between Cerbo GX and Multiplus2
- between Cerbo GX and MPPT RS 450/200
- between Cerbo GX and Touch 50
???
Thanks in advance for your help
Regards
Ralf
