Hi all!
Just want to say this is a great site and I've learnt a heap from it before I actually joined; solar seems like one of those things that you can get be amazingly good if you get it right or an worse than nothing at all if you get the calculations wrong.
So bearing that in mind, I have done my best to calculate my very basic system to install on my overnight boat, but I thought I would post the details here as I know there is always more to learn.
I have only purchased the panels so far, and I thought it would run it past this forum before I go further.
2x Conergy 180W panels wired in series or parallel, based on the calculator below, I should be putting out less than 100v if I go series, even at 1 degree Celsuis, which is highly unlikely where I live. Parallel would not be a problem voltage wise obviously.

I am running 2x Enirgi M2000 deep cycle batteries of approximately 100Ah each.
Considering the above, and being that the panels will be providing 360W / 12V = 30A, I have decided that an Epever Triron will be the best option for these panels as it provides enough leeway in the voltage for the panels, whereas a lot of other controllers max out at 50-60V.
One thing I am confused about is what amp rating do I need, because the panels say that their max Isc is 5.2A x2 panels in parallel = 10.4A I believed you had to divide panel watts by battery voltage to get amps, which gives me 180W / 12 = 15A x2 panels in parallel = 30A. So I'm somewhat confused as to what sized Triron I should be purchasing.
Any thoughts appreciated!
Cheers
