I have a 3 Phase system where the 3rd phase feed-in current follows the 3rd Phase critical loads current. (Yes, it's weird, but true). Feed in current (from DC MPPT, no AC MPPTs in system) is set to zero.
I attach two examples around 1.2 kW and 4 kW at different times. Feed in roughly follows critical current.
System is just installed so all software at latest version. (3 x Multi-2's = version 485). 2 x MPPT 250/100 = v3.07, Cerbo = v2.72.
ET340 meter installed. Externally metering set.
ESS installed, Set to Optimized (without battery life).
Multiphase regulation is Individual phase.
DVCC on, Forced by BSL batteries.
Why is this happening ?
