Why I need to Change multiphase reulation to Individual phase from Multiphase?
During winter I decided to use batteries to benefit from night tariff. Charging batteries at night and use during rest of day.
What I realized that I am exporting energy on two phases and import on one while I am using batteries and my inverters are far from max load. This is not visible during summer because I export to grid under net metering contract.
The problem I have that everything I export are charged by 35% from exported amount due to net metering contract with grid provider. They measure each phace separately. I use Grid code Europe EN50549
I assume this is due to Multiphase regulation set to „Total of all phases“ And swithed to Individual phase - this is the way how my grid provided is measuring.
The problem is that Cerbo revert it to Total of all phases as soon as I leave settings page
