I will be ordering 200w of solar on Monday from Renogy. What do I need to order to have everything I need to install? It is going to be set beside my Honda element. Currently it will be connected to my dual purpose marine battery. I need it to be as inexpensive as possible. Do I need fuses for each panel? I have the panels pwm controller 2 10ft extensions and a battery tray cable as well as 1 each of Renogy fuses. Is that all I need? I may not have net access again until Monday when I come down the mountain to order after checking the thread..... Thank you
