hi guys,
I finally got my system set up after 1 SOLID year of researching solar PV here there and everywhere and 5 years of solar home building research and planning.
I built my passive solar house with pv in mind. No penetrations on the south side. The optimizer said 32° roof angle facing 4 degrees west would be optimal. my house has a 35° roof angle facing, wait for it, 4 degrees west.
huge thanks to @timselectric and @Hedges , without whom I couldn't have done this. the copious amounts of help they provided in private was invaluable. THANKS!!!
The system:
two sunny island 6048 low frequency inverters from ebay. They are well used. 70k hours each, from 2012, work as good as new, at least for now
-fans dont come on until after 10kw and even then they are very quiet. Ive only heard the fans once.
-they LAUGH at surge loads, not even a thing. these things have 100a surge capacity combined
-they perfectly ac couple my growatt inverter
- oh, and only 50watts total idle load!
the grid tie inverter is a growatt min 11400tl-xh-us
-its fanless and quiet, up to 98.5% efficiency.
-4x 600v mppts, up to 22kw of pv input
-during the day it adds to my total inverter capability so 12kw from sunny islands and 11.4 kw from growatt for a total of 23.4k of inverting capacity.
-works with solar assistant
-and will throttle the output based on instructions from the sunny island
batteries:
-currently total 28kwh CATL 280h packs from batteryhookup.com
-jk 200a bms for each
-nader 125 a circuit breaker
panels:
-28 canadian solar cs6r 400w panels for 11.2kw of output mounted to my r-panel roof with
-s-5 protea brackets and
-iron ridge rails
-two strings of 14 panels each, voc of 515v
very near Future plans are to add another 5.6kw of panels and I ordered an additional 28kwh of batteries today from battery hookup. Good thing I left space on the roof for a 3rd row of panels
once stage 2 is done my power bill should be zero every month and the poco should owe me 9/12 months. currently im not tied to the poco.
