Hello there!
I am trying to figure out something rather simple but can't find the answer:
* The system is a three-phase system with three Multiplus II 48/5000. There is also a Fronius Symo 8.2 connected at the AC OUT of the victrons.
* Grid is connected to the AC IN (Spanish grid).
* Victrons have a 20 kWh BYD LVS battery.
We want to allow exporting all excess energy towards the utility grid, while the grid is available.
If the grid fails, we want the system to keep running, without feeding any excess to the grid, and regulating the power output of the Fronius Symo, in order no to overcharge the batteries.
What would be the recommended settings for VE Configure/ESS? Would I need anything else like an external contactor? If the Grid code was configured to Spain, will the Victrons still work in the case of grid failure?
Thanks!
