I posted a week ago about the same system and thank those who responded in particular @MarekP for great advice and schematic.:-) I just found something in the manual which has made me wonder if i have this correct-
offgrid system 2 x strings of 5 (380w) in series
just read below in victron manual and based on the pv and manual instructions (in italics) do i need another mppt and obvi
ously isolator rated the same the for the other 5 panels? so eventually 2 x 5 in seies
i take it i need additional mppt for the other 5 panels?
I was going to earth each panels daisy chained to eath rod as its on a pagola in the garden these 5 go to isolater 16a x 600v 2 pole rotary (was assuming 32a too high?) via 6mm cables approx 6m from inverter
then from inverter 125a x 2 for - and + fuses - have i missed any isolators etc?
using 35mm copper battery cable to 2 x 3000 pylontechs
I have 10 x JA SOLAR JM60S20 380/M 3800w (is this also over the inverter rating?)
VOC 41.62 V
VMP 34.77 V
ISC 11.47 A
IMP 10.93 A
*from manual Minimum number of cells in series: 144 (4x 12V panel or 2x 24V panel in series).
• Maximum: 360 cells (10x 12V or 5x 24 panel in series).
