Read: Off-Grid Inverter Buying Guide: What to Look For in 2026 →The Axpert MKS 4 3600-48 is rated 3600VA/3600W. That is the continuous figure and it is the one to size your load against; no separate surge rating is published for this unit.
The Axpert MKS 4 3600-48 takes up to 5000 W 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.
Peak efficiency is 93%. Whatever is not converted leaves as heat, so the Axpert MKS 4 3600-48 needs clear air around it and a mounting spot that is not the hottest wall in the building.
