My system comprises of 3X MPPT 250/100, 36X JA 370W, 8X Pylontech US3000B and 1X Quattro 15KVA.
On cloudy days, I've observed that the Quattro goes into passthru mode every time the power from the PV peaks over approx. 13kW during cloud edge effect events.
Why does this occur and how can I prevent it?
