Frequently Asked Questions

The Axpert MLV 6KW is rated 6000VA/6000W. 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 MLV 6KW takes up to 4000 W x 2 of PV array. The string has to stay below 145 VDC open-circuit — that ceiling is reached on a cold bright morning, not at noon.

Peak efficiency is 96%. Whatever is not converted leaves as heat, so the Axpert MLV 6KW needs clear air around it and a mounting spot that is not the hottest wall in the building.
