Adding Rogowski to CerboGX

[VariCon (Gerald)]

Dear Experts,

for an upcoming project, we’d like to use brand new Carlo Gavazzi Rogowski Meter with an existing CerboGX.

There is a Gavazzi Meter (EM530DINRG53XS1X) reading from Rogowski coils..
Due to current firmware, this one won’t be read by CerboGX:

Current thread:

Carlo Gavazzi Meter with Rogowski Coils

Dear Experts, For one of our projects, we are looking for an energy meter that is compatible with an existing Cerbo GX device. Due to structural constraints, we need to measure two conductors per phase (each phase has two wires with a cross-section of 240 mm²). To simplify installation, we are planning to use Rogowski coils in combination with a Carlo Gavazzi EM530DINRG53XS1X energy meter. Could you please confirm whether this solution is compatible with the Cerbo GX? I read the meter selec…

thanks to @ricardocello

I think you will need to recompile the dbus-cgwacs code and put it in /opt/victronenergy/dbus-cgwacs.

else if (mDeviceType >= 1744 && mDeviceType <= 1763)

should become

else if ((mDeviceType >= 1744 && mDeviceType <= 1763) || mDeviceType == 2096)

Does anybody know if this adjustment is possible on a specific CerboGX device?

Thanks

Sure, that is not that difficult if you know what you are doing, see:

see howto install and use the sdk · victronenergy/venus Wiki · GitHub or
compiling on the target · victronenergy/venus Wiki · GitHub

Ok, cool.
I never tried reprogramming a GX device.
Let’s see if I am able to do this….

Thanks

Hi,
We have the same project with Em530 RG. Did you get the programming done and does it work?

Dear Greg,
we are currently working on it.
I’ll keep you updated.
