Greetings,

Can I connect 2x405Wp panels for a total of 810Wp in 1S2P configuration on the Axpert MKS 3K-24 (PF1) without any issues?

Inverter SCC specifications are Voc 75Vdc, Max PV array power 600W, MPPT range 30~66Vdc and Max PV charge current 25A.

Jinko Cheetah HC 72M panels STC/NOCT specifications are Pmax 405/306Wp, Vmp 42.0/39.8V, Imp 9.65/7.72A, Voc 50.1/48.7V and Isc 10.48/8.22A

General guidelines here and other forums [FAQ 5] advocate maximum 12.5-20% oversizing but I cannot find panel sizes between 350Wp and 375Wp. 

Thank you.

I've relaxed my recommendation maximum oversizing a bit, I suspect that 25% is generally ok. Your proposal is 29%, which I think is still too much. Can you find a pair, say 360+410 or 375+410, where the Vmp are within 5% of each other?
