solar panel connectors
What are the pros and cons to TYCO connectors vs mc4 and do they make some type of y connector for Tyco or should I stay away from tyco.

Run Morningstar string calculator for 2*255W in series to make sure the maximum Voc is below 150V at low temps like 20F for TS MPPT 45.
I haven't heard of big panels breaking on trailers - this has been discussed too, you can reinforce the panel frame and/or add more mounting brackets.
510W will harvest more energy than 400w, no matter what controller or series/parallel.
With Tyco connectors you need to buy Tyco extension cable (they exist), and Tyco Y-connectors if wiring parallel (don't know if these exist). Maybe shop around and find 2*255W with MC4, this type is prevalent, plenty of cables and connectors. 260W MC4, $234
Edit - PS: forget about string calculator for TS MPPT 45. 2*255W or 2*260 will never exceed 150V.
the cost for the big panel system with 45a MPPT about $906 and the 4 small with a 40a MPPT is $903 but I called Solar blvd and he said I could use a 30a MPPT and solar Blvd carries Tyco wire. I was going to use 6 anchor points on the big panels
