I have several questions based on the installation
and hope someone would answer them. I tend to like to have a plan and full understanding of what is going to happen before I spend a dime so please bare with me.
I haven't fiscally looked at any of the pieces but here is what I hope to install on the davits
of my Catamaran
2-240W panels, moncrystalline by Kyocera
. Probably 24V
I also like the Solarworld SW 255 but am concerned about them going into bankruptcy. They seem to be very strong and have a high rate of efficiency. Comments or concerns on these would be appreciated.
My first choice is the Morningstar TriStar 45. Unlike the Outback it has a remote
display. I also see it doesn't have a fan and conformal coated.
I plan on running them in series to a fused junction box 10 feet away then to the MPPT another 6 feet away. The batteries will be within 3 feet of the MPPT unit.
I see that most solar panels
have a Jbox at each panel. There are (2)whip wires I believe have an MC4 connector at the ends. So you plug
the first panel to the next one in the solar Jbox correct?
Now at the last one (the one that is going to the fused Jbox) can't use the MC4 connector. Is there normally a terminal strip within the Solar Panel Jbox to convert to standard marine
If there was a "power out" MC4 wire is this just removed from terminals at the SP jbox?
I plan on running the wires inside the davits
and assume it's just 3 (probably a minimum of #10) a hot, neutral and ground. If I wanted to convert these to parallel in the future would I need to run 4 wires (2 hots) back to the fused Jbox in the davits? separate grounds or neutrals wouldn't be necessary correct?
I may run an extra wire "just in case" anyway.
Also I assume for a parallel arrangement that the panels are wired only separately to the fuse jbox? after the Jbox they can run to the MPPT controller on the same wires?
Honestly I have searched many sites and the installation instructions are hard to find and no straight info available unless someone can point me in the right direction.
Any and all help on this is appreciated!
