The 6000xp manual shows a PV unit startup voltage of 100V and I am not sure what this means. I will have about 270v from my panels. Can I start the system with this voltage connected? What is the significance of the 100v? Is that the minimum that must be connected to the MPPT?

Thanks
 
It is also the voltage that needs to be produced. Your 270v probably assumes all panels are being lit up. Early or late in the day, cloud cover, etc will drop production. If not 100v, then string is ignored.
 
Hmmm, this has me reconsidering the 6k Luxpower now...

I have a variant of the Voltronic 6548 with the 250VOC capability. I only really have room for 2 strings of 5 405W Longi Panels and they seem to sit at 90-ish volts until the full sun comes through.

This 100v limit makes me think the 6kxp will lose out on a few kWh that the Voltronic can make use of.... in less ideal conditions.

Yes. I think next model will have lower lower end and higher higher end. Midnite AIO ranges for 70v-600. Tesla Powerwall 3 60-500v.
 
I have two strings of 4 545w panels and they are 49v panels. Right now it's early morning and it's raining. No solar coming in at all but they are reading 163v. So even in those conditions I generally will see at least 40v on these 49v panels.

The minimum to start the inverter with solar would be 100v. However, the inverter would not power loads until the usable 120v is reached. In some cases, I see that it has to be 121v.
 
Maybe I would have to run my 10 405W Longi's in a 10s configuration... would be about 400V 13A max... for one MPPT though.

Early morning would be ~180V and typical mid-day would be 360V where I am..
