Question 1: I am building a solar light trailer. I have two 250W 60 cell modules with Vmp of 30.1V. (I would have bought 72 cell modules, but these were donated) Is it all right to put them in series which could exceed 80Voc in cold temperatures. I don't know why, but I was under the impression that mobile solar was not to exceed 50V DC.
Question 2: The charge controller is a Morningstar PS40 MPPT. It has a system ground terminal that the manual says must be bonded to a permanent earth ground. Can the trailer frame safely take the place of the earth ground?
Question 3: Do the module frames and other metal components have to be bonded to the trailer frame?
Question 4: Why is there no mention of grounding in the mobile systems displayed on the this website? Am I missing something?
Again...I'm new to mobile solar.
Thanks
