Adding second inverter to Elgris Smartmeter

Good day,
I’m using an Elgris Smartmeter to control my inverter (dynamical control of the power limitation).
Via Emoncms I’m monitoring the current solar generating power and this works fine.
Now, I’m using a second inverter to implement a battery into my power system. In the Elgirs Smartmeter I can integrate additonal inverters (of course with another Modbus addresss).
My question now: how can I integrate this second inverter to Emoncms (via the Elgris Smartmeter) to monitor also this inverter?
