So, So, a rough estimate would be approximately 289v would be okay down to -40 C. So, my 240.9v going into an MPPT with a max of 450v would be perfectly fine.

I'm looking at the 390w model. I'm looking at wiring them in two arrays each of 5S2P for a total of 20 panels. Each of the two MPPT's can handle a max of 450vdc input. So, 48.18v * 5 panels = 240.9v at 20.96a to each of the two MPPT's. So with my equipment that should be (450v - 240.9v) /...

All: I am planning to buy a pallet of these panels from Signature Solar: https://signaturesolar.com/content/documents/Hyundai%20Solar/HiA-SXXXHI_M3_(380_405)_(19.12)_cs6.pdf Can someone tell me how to figure voltage, amperage, and wattage increase due to bright sun and cold temperatures...

I e-mailed Signature Solar tech support. He confirmed that the Voc limit is 450v per MPPT. So, 450v each.

Okay, so I found some panels that I think would work perfectly with my roof size and layout as well as maximizing the EG4 6500EX-48 charge controller/inverter. Santan Solar has some new in box 390 watt Canadian Solar HiKu panels with a VOC of 44.1 and Isc of 11.38...

How hard a limit is that 500 Voc rating? I'm looking at a panel setup that tops out at 508.

I am actually planning on buying this: EG4 6.5kW Off-Grid Inverter | 6500EX-48 I understand it has dual 60 amp mppt's in it.

I am looking to wire up the above panel configuration. The voltage of the 5s2p string would be the same as the 5s string, correct? If this does work, how would the wiring look if the panels were laid out physically as in the attached picture? Also, I have been trying to find an online tool...
