I recently installed 7 Jinko panels these ones, and have noticed they produce well over rated power for roughly an hour a day (4.5kWh). At first I was impressed, delving into the values this morning I realized that the amps were actually being clipped at 16.2, which, is the MPPTs max amps.

Now I am wondering, if this would have any negative effects on the warranty of the inverters, and if it could cause any issues except for the inverter possibly shooting up a couple of degrees in temperature 

 

The inverter being used is the Solis S6 6kw

add details.

Generally speaking, as long as the voltage doesn't exceed the MPPT maximum you should be fine. Modest over-panelling (to account for cloudy days!) is a pretty common practice; even if it does produce a bit of midday current clipping.

 

Regarding your setup: 7 x 555W panels is 3885W, the inverter PV maxes out at nearly double that, right? Is it 7 panels in total - or 7 new panels added onto an existing set of panels? (How many strings are you running, if it's just one, would splitting these across both MPPTs help with preventing clipping in this case?)

So it's a single string, only 7 panels on a single string. 

The MPPT's limit is 350v and 16.2a, so around 5670w theoretical max. However, the max voltage for 2 strings is 600v.

The idea is to add another string before Feb to maximize on the rebate before the financial year end.

This does not make sense. Or rather, I'd be careful, have it checked out, and try to limit the power.

The panels in the link have a rating for Isc of 14.07A. Your inverter might be fine clipping the amps at 16A, but the panels are operating outside of their normal limits.

Unless I'm missing something.
