This morning I went out on the roof and hooked up the enphase cabling. Next step was to move the panels onto the roof. I used the 1 1/2 inch stainless screws into each panel to stop the panel from sliding down the rail on the slanted roof. this worked well although I probably would feel more comfortable with a 2 inch long screw if it would fit but the 1 1/2 was a good solution. the connectors needed a lot of pressure to click them together from the panel to the inverter. They have a gasket which makes mating difficult. It's necessary to squeeze together until there's a click. I ended up having to slide the panel to the side so I could grasp the connectors with two hands and squeeze. I Put all 4 panels on the roof and also hooked up a disconnect switch panel on the roof. For Libbie's traditional pizza tonight I chopped up a slice of Vidalia and added some thai and regular banana pepper to my half of the pizza. I love the heat from the thai peppers.
