We're willing to use to cerbo gx on the same intallation, but we're not pretty sure if we can connect them together to send data in one package and to connect both of them to the same gx gsm modem
asked
It's possible to connect 2 cerbo gx? one as a master and the other one as a slave?
It is possible to parallel two identical units to double the power but this is not result in a redundant system. If one unit goes down, the other paralleled unit will also turn off.
Cerbo GX will control at most one inverter/charger. This includes multi-phase and/or paralleled units which appear as a single Multi/Quattor to Cerbo.
@Juan Restrepo no you can not run 2 Cerbo GX in parallel or for redundancy, unless one is powered off and you manually power it on.
Only one Cerbo GX can be on the VE.Bus at any one time. Having two will create unknown issues.
Even worse things happen if you have NMEA200 and the NMEA2000 Out capability used. That will mean that everything fine system knows about will be visible on the other and visa-versa.
In terms of the GX GSM Modem, that is USB connected, so can only be connected to one Cerbo at a time. A Cerbo GX with a GX GSM Modem, will not provide network access to other systems on the WIFI or LAN, aka it is not an internet gateway.
Bottom line it is designed as a 1 x Cerbo to 1 x System.
