Size the load you actually intend to run against the continuous figure, never against the surge one.
The Axpert VM III TWIN IP52 4K takes up to 6000W of PV array. The string has to stay below 500 VDC open-circuit — that ceiling is reached on a cold bright morning, not at noon. The tracker works over 60 ~ 450 VDC, so wire the modules to land inside that window.
Peak efficiency is 93%. Whatever is not converted leaves as heat, so the Axpert VM III TWIN IP52 4K needs clear air around it and a mounting spot that is not the hottest wall in the building.
