Maximum recommended PV power ,400 Wp
Grounding internal function grounding of the negative input for connecting amorphous and micromorphic thin-
film modules
Derating / limiting automatic when
- input power is higher (> 1,075 W / input)
- the device is not cooled sufficiently
- input currents > x 8 A or 1 x 16 A (parallel inputs)
(higher currents are limited by the equipment and therefore will not damage the inverter)
