PV Watt vs Volt /Amp max ratings

Featured Replies

Hi all and sorry in advance if this has been covered but all the threads I found seem to get side-tracked before a conclusive answer is given...

I have an Axpert King 3K which has the following PV ratings

Max PV Array = 1500w
MPP Range @ operating voltage = 30 to 115V
Max PV Open Circuit Voltage = 145V
Max Solar Charge Current = 60A

Currently I have 4x 360w Canadian Solar Panels with the following specs per panel (STC)

Operating Voltage = 39.6V
Operating Current = 9.1A
Open Circuit Voltage = 47.0V

My current panels are configured as 2 panels in series x2 connected in Parallel equating to the following on paper in theory (please correct me if I am wrong)

Voltage = 79.2V
Current = 19.2A
Open Circuit Volage = 94V
Max Wattage (in theory) = 1440w but in reality ICC has reported bursts maxed at 1625w

My question is, could I add another 2 panels in series to increase the array to x3 in Parallel?? The theoretical max output would be as follows

Voltage = 79.2V
Current = 27.3A
Open Circuit Volage = 94V
Max Wattage (in theory) = 2160w 

The important part of my question is what is most important max Volt & Amps or Watts or both?

My confusion comes in, is the 1500w PV Array limit does not line up with the other limitations and seems to be way under
