My client wants to measure power use in each room in his Safari Lodge, actually he wants to measure 8 different DB boards which are distributed around the safari camp, it is going to be a 90kW or a 135kW parallel quatro/fronius ESS system
I have an existing DB cabinet where an isolator for each DB board lives, so I can install a second row of 8 * EM24 meters (Modbus TCP) an ethernet hub for the 8 meters and use the Carlo Gavazzi software to provide management reports for the owners of the Safari Lodge, I can even install the cerbo before the rest of the solar system, either way I will then know for sure which I need a 90kW system with 75kW panels and 160kWh battery or a 135kW system with 100kW panels with a 240kWh battery
So the question is what do I do about the Cerbo GX, will it recognise all 8 EM24 devices as Grid input (is there a limit on number of em24's specified as grid input or a modbus limit ?) and will it list all 8 as separate devices and aggregate their power into the Grid input total on the touch 50 graphics, will this work . . .? or will I end up having to install a 9th em24 device just for the Cerbo with 3 * 400A CT cables to measure the 120mm Grid transformer cables before they are split up into the 8 DB boards
