The system is composed of 1 Venux GX connected to 6 inverter Quattros with the generator connected to the AC-IN-1 and no Load connected to the AC-OUT
The firmware version of the Inverter is 430
We want to control the charging of the inverter by setting our own loop control using an external device to send command on the Venux through the register 37, 40 and 41 (/Hub4/L1/AcPowerSetpoint, /Hub4/L2/AcPowerSetpoint and /Hub4/L1/AcPowerSetpoint)
During our testing, the generator was running, the SoC was around 45% and the system was stable.
A 100W was send to each register listed above. According to the documentation of the ESS Mode 3, the expected outcomes would be reading 100W on the AC-IN of each phases of the system. However, the observed outcome were reading value of 3300W, 1300W and 1500W respectively on each phase of the system, overload alarms raising before the system went Off.
We have tried this operation a total of 3 times, every time we observed the same outcomes: Command sent was not respected and system went Off after the overload alarms raised
Why is the command not respected and the system is going Off ?
