Hi all,
my ESS system connected to grid is build with :
Cerbo GX v2.92 + GX Touch display
multiplus2 48/3000/32 v500 connected to VE.Bus version 2629500
RS450/100 v1.10 connected to VE-CAN
ET112 v4 connected to /dev/ttyUSB0
1x US2000C connected on Can-bus, version not displayed on GX Touch, SoH 99%
I am considering to add a second US2000C
I have read this:
https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom#gx_device_settings
can any one confirm if this plan sounds right :
switch off the entire system :
PV breaker : off (ideally not under load)
AC/out breaker : off
AC/in breaker : off
house grid breaker : off
battery breaker : off
battery n°1 power switch : off
keep battery n°1 connected to Can-Bus, it will remain Master
check battery n°2 dip switch : all on 0
connect battery n°2 to ground
connect battery n°1 link port1 to battery n°2 link port0
connect battery n°2 Plus to battery n°1 Plus
connect battery n°2 Minus to battery n°1 Minus
system power on :
battery n°1 power switch : on
need to press battery n°1 SW red button ? (GX device already 'knows' that battery)
battery n°2 power switch : on
wait a little while for batteries to complete software start
=> do I need to wait for batteries to balance ?
battery breaker : on
AC in breaker : on
house grid breaker : on
AC out breaker : on
PV breaker : on
wait for multiplus2 to complete startup, ESS system should be back online.
from there, and considering GX device v2.92, I understand both batteries will be automatically integrated in the GX device config, including DVCC values adjustments,
battery CCL & DCL should jump to 50A,
battery CVL should stay at 53.2V,
Is it really simple as that or am I missing anything ?
