Reverse polarity protection Yes
Maximum DC input power 1,000 W [per input]
or
1,000 W [2 parallel inputs]
Maximum recommended PV power 2,200 Wp
Reduction in power / Restriction Automatic when
- input power is higher (> 1.000 kW/input)
- the equipment is not cooled enough
- input currents > 2 x 8 A DC or 1 x 16 A (parallel inputs).
(Higher currents are restricted by the equipment and therefore will not damage the inverter)
