Hi John, the two terminal bars you point to with (here, here in the figure) are for the PV+ terminals (i.e., the positive leads coming from the array). In the pre-wired systems there is a wire coming from these PV+ terminal blocks to the individual PV Input breakers. I would take your PV+ wire coming from your new array, put a ring terminal on it and attach directly to the new PV input breaker you will be installing.grunt wrote: ↑Mon Mar 16, 2020 5:36 amSo both charger controllers have their own line as you can see in the pic. There is no rail for the third charger to land, as i am adding it after the pre-wired system is already configured. Now looking at it, it does not look like that big of a deal as the bars only server as a rail for the breaker and the panel to meet. So I guess I just need to deiced how I want the to do that, correct ?
The OB Cat5 cables are standard straight through Ethernet cables. They are not shielded and there have been reports of noise issues fixed using shielded Cat5 cables.grunt wrote: ↑Mon Mar 16, 2020 5:36 amAlso and I don't think it really matters but can I use any type of Cat 5 cable with j45 connectors to hook the third charger controller in to the hub or is their some type of propitiatory cord I have to use to hook the two together? Also, in the schematics it shows that the charger controllers cat5 cables are hooked up in the inputs at the top of the hub, with what I believe is the DNC, they take up ports 1,2, & 3, respectively.. buuuuut in the pre-wired system, those cables from those units are installed at the "bottom" side of the hub ports not at the top and occupy 8, 9, and 10. Does that matter, where they are located in the HUB ? if not I will use port 7 for the third C.C. than.
With the ports on the HUB10.3 facing down, the Mate must go into the far right port, the next port to the left is for a 2nd Mate which is not supported. Then come ports 1 thru 10 from right to left. Always install the master inverter, which in your case is a Radian in port 1. After that per the Hub10.3 Overview Guide any unused port can be used to host other devices. My experience is that the order of installation does not matter. The order on my own system is: 1) Radian, 2) CC, 3) FNDC, and 4) CC), which just happened after I got my Mate 3 and Radian in the correct ports. I have not tested @pss's advice on not skipping ports, but the Overview Guide does not state such a restriction.
If you are reading this and do not have a single Radian system, review the HUB10.3 Overview Guide for your specific inverter and configuration.
