Hello,
I'm really hoping you all can help me out....and appreciate it in advance!
I'm here in California and I currently have a solar array which consists of the following:
*30 Solarworld 285w panels (Broken up into 2 strings of 15 each)
*Solaredge P300 Optimizers
*Solaredge 7600 inverter
*Current wire used is 10 awg 1000v DC PV wire.
Here is my new project:
*Add 4 new Solarworld 290w Panels to my existing system (2 onto each string, so new total will be 17 panels on each string. This has been OK'd by Solaredge)
*4 new Solaredge P320 microinverters.
*Quickmount PV racking and replacement flat tile mounts
*Quickmount Tile Conduit mounts
***My question is this. As per code I'm going to run EMT conduit from my current racks on my south side roof to the new panels which will be on my west garage roof. That run is approx. 30 ft. I'm using 3/4" EMT which is over kill to run a total of 4 - 10 awg PV wire (2 wires from string 1 and 2 wires from string 2) to the new west facing array. How do I come off of the racking system of my current south facing rack and connect to my new west facing racking? Can I use a 1-gang weatherproof Box with 3/4" holes on each end and then couple that to the 3/4" emt? Also, I need to use water-tight strain reliefs where the wires will be going into the box from the arrays, so is it ok for that to be PVC or does it have to be metal for the EMT? I can run PVC Junction boxes and EMT together right? Or do they make a waterproof EMT box that I'm suppose to use with EMT conduit?
Lastly, where do I mount the junction boxes? Do I drill holes in the PVC Junction box and attach it with 2 bolt to the side or bottom of each rack? I basically want to be sure I'm coming into the box correctly and going out of it correctly and want to be sure it's ok to use the PVC junction box with EMT conduit. I'll also be using water tight emt couplers to couple the emt conduit together.
Thanks!
