Good day to you too Kaarthik.

It's ok to exceed the nominal W spec, but *never* exceed the string Voc, nor parallel string's total Isc (edited V to I). Victron would be quite within their rights to reject a warranty claim then.

Not saying they would, cos goodwill goes a long way.. But exceeding those particular things is asking for failure, and someone's gotta pay.

Other branded solar panels are no issue. They work the 'same'.
