Good afternoon,
I appreciate all the help over the last year or two. I’ve tried to put pen to paper and start listing out my actual components. Install would realistically begin in September, once it cools down.
I don’t have any graphic design skills but I will try to make this clear with words.
Any input appreciated before I get too deep down this rabbit hole.
The strings are convenient given the layout of the roof, and that they work with the charge controller. But not set in stone.
Off-grid. Generator on site (7500W).
Power audit max consumption at 110F=approx 1500W/hour continuous with air condition mini-split load. We have had 100 days over 100F. I am assuming a high duty cycle on the air conditioning. Also, there is a strong correlation between the high temps and full sun and cloudless skies.
46 panels (purchased used).
Roof mount.
(295W, Voc 40.1A; Pmax V 32.7; short-circuit current 9.52A; current at Pmax 9.03; max system voltage 1000V) (Spec sheet attached. The numbers below are from actual panels)
2 strings of 9 panels (9*40.1=360.9V per string)
4 strings of 7 panels (7*40.1=280.7V per string)
6 strings total
Short-circuit current 9.52A
Combined (2x) 9-panel strings=9.52A*2=19.04A (feeding 1 mppt input)
Combined (4x) 7-panel strings=9.52A*4=38.08A (feeding 2 mppt inputs/19A each)
Midnite MNPV6 Disconnect with breaker
Victron Smart Solar RS 450/200 (4 mppt trackers)
Victron Multiplus 3000/48/35
48V/100Ah SOK batteries (starting with 4)-ordered.
Various Victron bits and pieces (Cerbo GX, Lynx, etc).
I think the panel array matches nicely with the Victron RS 450/200. Slightly over-paneled. Max DC output is 11,520W. Theoretical max of array is 13,570W)
Any input or thoughts much appreciated.
Thanks!
