First Solar Installation...
I'm going to do my first solar system install shortly and am gathering as much info as I can before proceeding. Trojan battery and AM Solar Rocker hardware on the way; Grape Solar panels, Zantrex charge controller and inverter in hand; and Trimetric 2030RV coming also.
My question has to do with penetrating the roof to run the MC4 cables inside. What method/ hardware is used to do so? I can't see drilling a hole through the roof large enough to fit the MC4 connectors through and filling with SikaFlex. It seems I've seen a video where someone had a junction box mounted up on the roof.
Any comments would be greatly appreciated.
