Hello, so I have some solar panels that can generate 6kW at max and would love to add a battery and buy a Victron Multiplus II of 5kW as I think that should be enough for me and don’t want to spend much more. The Energy Storage System I want to do is the one in the image (in parallel) as I cannot connect the 6kW inverter to the output of the Victron (I know the drawbacks but I don’t mind).
The problem I am having is that I am not understanding how can I tell the Victron (I guess with a Cerbo) to only take excess energy that the loads are not using and keep it in the battery, and whenever the loads actually need more power to take it from the Victron. Would it be enough to put a meter like in the image and then send the info to the Cerbo? Or do I need to keep the inverters communicating? How should I do this?
The inverter is Solis-1P6K-4G I am not sure if it could communicate with Victron or how.
