Hey!
I’m planning a domestic battery ESS and I’m wondering if it’s possible to feed to extra ET112s into a Cerbo GX. You need one to monitor the incoming mains, but I’d also like to monitor the radial feed to the outbuilding where the battery will be and the radial to the EV Charger.
I want to be able to get the charger to lower it’s load should the load on the cable to the outbuilding get too high and ensure that when there is a significant load to the EVC, the MP-II is charging the battery, not providing power.
The planned layout is:
The two ET112s in question are shown with purple connections.
The alternative would be to use a Shelly EM and do the automation in Home Assistant.
Does anyone have any experience with adding additional ET112s into a Cerbo GX?
Can you connect basic CT sense to the Cerbo?
Thanks!
