I've been struggling for days with a 3 phase ESS system and its symmetrical phase compensation which was introduced with v2.80 (https://www.victronenergy.com/blog/2022/01/31/venus-os-v2-80/ -> <#10 ESS change for multi-phase systems configured to “Total of all phases” mode>.
- 3 phase Multiplus-II 48/3000/35-32
- Venus OS 2.89
- (Grid tied Fronius PV inverter Symo 10.0-3-M)
- Zero Feed-In
- No AC-out
- EM24 meter
L1 inverter seems to not deliver its share to compensate the meter to zero / Grid set point "20W" for all kinds of load:
All screenshots where made after system had sufficient time to stabilize.
Notice how L1 (master) inverter insists in idling around while L2 (slave) and L3 (slave) do all the work, resulting in a constant net meter reading of about 1/3 of the overall load.
Do I have any misconfiguration in my system, or is there still a problem with ESS symmetrical phase compensation?
Any help is kindly appreciated :-)
