They also have a T90, 14/1 stranded, "For wet locations, gasoline and oil resistant applications not to exceed 60°C." They have that one in black, white and green jackets. Is #14 in green ok for a ground wire from my inverter to the array?
My array is a ground mount. I have a 4" conduit already in the ground. I don't want to spend more than I have to for the cable. I have found this: https://www.homedepot.ca/product/southwire-14-1-rw90-300m-electrical-wire-white/1000400185. Also, they sell it by the meter. I need 45m per run.
Thank you for you replies. 14\2 I can find at Home Depot is only rated for up to 300V. They have 14\1 rated for up to 600V. Each of my strings might be running higher than 300V. Installing multiple 14\1 would be more time\effort, but this might be something I need to do. Also, for the ground...
I have talked to Sol-Ark support, and they have confirmed 10 Amp limit per MPPT on my inverter. So, my plan to run 3 strings of 8 panels each might not be best for my inverter. With 2 strings of 8 panels on first MPPT my input current would be ~16 Amps, so 6 Amps would be wasted. I don't know...
Thank you! Thats exactly what I believe I should do after doing more research. I just realized last night tha I should be using Vmp for calculating minimum string voltage. Also my panels are 10 years old, so they might be producing less. I'll be connecting all the panels with a ground wire, and...
I'm sorry if this is a duplicate, but I don't see my reply from 4 hrs ago. My Sol-Arc is 120/240V, model Sol-Ark-5K-48-ST. According to spec sheet I've found online: MPPT voltage range is 150-425V, max DC current per MPPT 10A/10A. It could get down to -40C at times, so I'd like to play it safe...
I have Sol-Ark 5K inverter, 22 x 230W (CS6P-230P panels). Also I bought Midnight Solar MNPV6 DC Combiner Box with 4 15amp DC breakers. From what I understand this box is configured as a junction box for 4 strings. Each string would be wired individually to 15amp DC breaker and wired via 146'...
