This issue as been discussed before, but still it is a problem - and a very serious problem
I have a grid-tie 3-phase multiplus 3000/48-32 setup with ESS
In VenusOS I have set grid point to 500W (cut everything above 500W) and I have set "Multiphase regulation" to "Total of all phases"
I now expect the battery system to keep a maximum of 500W imported power.
This is not happening.
When I turn the own on, the total on that phase exceeds the power the victron can give at the moment.
The inverter on L2 is doing what it can, but it cannot compensate for the full load, and 500W is beeing bought from the grid.
The other two inverters are not helping L2 to zero the feed in. They are just zeroring their own phase.
L1 627 W
L2 3179 W
L3 130 W
L1 164 W
L2 683 W
L3 105 W
Solar about 40 W per phase
Total from grid: 952 W
Expected is 500W
When L2 has reached its maximum, L1 or L3 should produce mote power, and even sell power to keep the grid point at 500W
There is no differance in behaviour between "Total of all phases" and "Individual phases" The result is exactly the same. There is no change what so ever.
Expected behaviour is: If grid point is set to 500W, This should be obeyed at all times, even if two phases are selling and one is buying, as long at the total is equal to the grid-set point.
This is a MAJOR bug. This makes the ESS useless out of a zero-feed-in scenario.
Most electricity companies where I live have "Total of all phases" as their means of billing.
"Total of all phases" = make total to grid-point even if it makes other phases sell or use more power that the individual phase requires
Attached pictures show the system with a "grid set point of 500W and "total of all phases""
Yet it is still importing 452W more that expected, even thought L1 and L3 are hardly doing anything (especially L3)
