@Vassen Thanks for clearing that up i tought it would be 600v i was 😕 confused apprcitaed.

@Leshen Hi Leshen wolud the Voc not be 445.05 . Its JA 535watt 49.45 Voc STC. Or is it another model. Because im stuck between a rock and a hard place trying to get the most off the mppt on the Sunsyk 8kva second mppt any suggestions.

@Leshen Just a question the Voc on 9s 2 strings is that Noct?

@Vassen Just a quick one my exsiting Art Solar are 400watt STC Voc 49.1 i think its not going to work as its 294.6 x 2 = 589.2 or will and if i use 5s 2 strings 245.5 x 2 = 491 with this be fine or do i need to go 5s and 4s remove 3 panels.

@YellowTapemeasure Thanks
