I have a Quattro 8000 with
BYD B-Box LV 14kWh battery and the
Sunnyboy 5000 solar inverter
Also using GX console
The systems work great, until the load on the Quattro exceeds 6000W. When that happens the Quattro suddenly increases the frequency to 51Hz, shutting down the solar inverter, which sometimes leads to the overload if the solar inverter was producing power
The ESS and the GSX are upgraded to the latest version. The BYD is not limiting the charge or discharge current when this happens
This behavior also happens at night
