13.84 Isc is at 0V (short circuit) = 0 W and 49.42 Voc is at 0 Amps ( Open circuit) = 0W . You see this represented at each end of the power curve. You multiply the Vmp x Imp to get power.

Hmm, that's strange. I see that too. I'll look into it now and let you know when I've updated it, hopefully tonight.

Check it out now and let me know if there is anything else. It should say Version 3.

Hi thanks for the feedback, I can try to make more portrait mode friendly in the next version.

No one has suggested it to be added. I can certainly add it. For now, feel free to enter the specs in the "Custom" mode for inverters or Solar Chargers that are not listed. I'll add it in the next update. Thanks!

Hi! Can you clarify your question? Are you implying and asking why do lower capacity inverters (smaller inverters like residential) have higher fault current contribution than larger inverters (utility scale)? If so can you share two models as examples so that I better understand the question and see the type of inverter and fault current ratings on both models?

@@uptopsolar yes my question is, why low capacity of inverter has max fault current contribution (1 cycle RMS) is more than high capacity of inverter of max fault current contribution (1 cycle RMS) . For example:- a. Cps inverter model name CPS SCA 36ktl-DO/US- 480 has fault current contribution (1 cycle RMS) is 73.2A (1.68 PU), while b. Cps inverter model name CPS SCA 60 ktl-DO/US-480 has maximum fault current contribution (1 cycle RMS) 64.1 A (1.6/0.88 PU).

I couldn't find the SMA manual that shows this, but from my experience with other inverters... MPPT Operating Voltage Range is where the inverter can operate and perform some MPPT, it's a wider range. Then Rated MPP Voltage range is the range where the inverter can out put it's max power. So in this example it appears that between 100Vdc and 155Vdc there could be some derating, same thing on the high end (between 480Vdc and 550Vdc). Between 155Vdc and 480Vdc, you could expect full power output.

@@uptopsolar Thanks for the information!

No, the voltage is immediately there the moment some light hits the string. The string generates however hardly any current as only a view number of atoms are hit by the light. Current generation will linear increase with the increase of light on the panel upto a maximum where the maximum output is reached. See an episode of Gerry does Solar.

Thanks, I appreciate the kind words!

It depends on the type of device. I have since renamed it to the overloading ratio since for the DC/DC converter there is no AC. For a string inverter it uses STC DC Power/ Inverter Rating. For the DC/DC converter, it would be the STC DC Power/Converter rated output. I hope that helps!
