OZ solar, I was going off a 9 panel wired in series diagram on the web...problem is, it just showed each panel connected to the other.
So..yea, I was wondering about the pos to pos and neg to neg connections. THNX for catching it and veryifying my doubts
the Total run is 275'. 100' would be inside a metal building and the remaining 175' would be underground. It's determined that we need 2 ga. aluminum cable.
So...we'd have 2 load wires, 1 neutral wire and 1 ground wire.
Per codes (or lack of codes in our rural area), we could run wire w/out...
WY treasure, the cost of the wiring ended up not too bad....the 2-2-2-4 Alum Service Cable (run indoors, 85') was $1.80/ft. The bury 2-2-2-4 AL MHF, (145') was $2.08/ft....PLUS, I had a use it or lose it rebate of $100+. Via the voltage drop calculation, we just had to go with a 2-2-2-4 on the...
Our Heliene 400w bi-facial panels are mounted on a green metal roof, about 1.5-2" above the surface of roof
Could we expect any residual solar energy from reflection(s) off the roof? Guess what I'm curious about, does some of the sunlight pass through the panel glass (which then could reflect...
We've always called your area "Thunder Basin" ...at least E. of Gillette. W. was considered the "Powder River Basin". "Our" Basin is on the W. side of the Bighorns
www.heliene.com
the "point" person there that we worked with was Matt Heaton.
I believe the best "deal" were the Heliene Bi-Facial Panels that are offered in several different wattages... and you have to purchase at least a pallet qty (I believe that equates to 26 panels).
Heliene is a...
This is for AC from inverter to Disconnect Switch Box. 2 gauge Alum. wire (budget constraints)
Most of the Disconnect Switches max out at accepting 2 ga. wire at the lug. Can we somehow make 2ga 'fit' into 3ga?
Tim, I 'think' locking means that the on/off switch handle can be locked. Again, I 'think'
What is the difference between indoor and outdoor rated boxes? they look the same
Inverter: Fronius Primo 11.4
The panels and inverter will be around 275' away from main box on house.
To save on wire, could I directly hook up a ground wire to Inverter AC lug and take it directly to a ground rod?
Also, I have the panel frames already grounded to their own ground rod, could I...
sooo....last week, Thur. Feb 2nd, Noon, we had our Net Meter Installed. I did not turn on our Grid tied PV system until Noon the next day, Feb. 3rd.
At Noon of Feb. 3rd, our Net meter showed ---> 28 kw h consumption from utility
Flash Fwd to today, Feb. 10th, Noon:
14 (consumed from our...
From the inverter, our AC cable is in a conduit, then goes underground, then back up the A/C Disconnect.
I know that the DC conduits call for a 1"x4" "Warning - PV Power Source" labels every 4'....how 'bout the A/C conduits?
we're good with the particulars of both panels and inverter....does the attached drawing represent a Single String, Panels wired in Series configuration?
Our grid tie system is 32 - 400w, 10 amp panels tied together in 4 - 8 panel strings. The DC produced first goes through a DC breaker box with 4 - 16 amp breakers, then to the Inverter. No combiner box....each string has it's own breaker
The other day, I noticed that string #3's breaker was...
We're getting closer to finalizing our Grid Tie project
Any recommendations for a Safety Switch (the go between between ac cable and the main box) that'll hook up to 240v, 47.5 amp 2-2-2-4 cable?
With 47.5 amps, do you bump up to 50 amp fuses? Again, this will be an outdoor location and the...
Hi Tim, you've been a lot of help on our solar project. Let me clarify my question: How is the AC (coming from inverter) hooked up to the Grid?
We've got the 2-2-2-4 cable hooked up to the AC Safety Shutoff Switch. From their, the AC needs to get to the meter. Will my electrican run wire from...
ok, found this, a 100 amp GE TGN3323 It's non-fusible and should right, correct?

Folks, I'd like to enclose the Fronius Rapid Shutdown "Quattro" Box within some type of weatherproof junction box BUT...having a hard time finding the right plastic box that'll fit the Quattro. Any ideas?
Also, the Fronius Specs say that the RSD unit has to be "within" 10' of the Array. Could...
Folks, I'd like to enclose the Fronius Rapid Shutdown "Quattro" Box within some type of weatherproof junction box BUT...having a hard time finding the right plastic box that'll fit the Quattro. Any ideas? perhaps a box with an easy latch open vs. having to remove screws to take cover off?
PS -...
Grid tie, 32 panel/4 array setup. Array #1 on far left gets shaded first (from an adjacent hill) in the mid to late afternoon.
Inverter: Fronius Primo 11.4, 1 phase, what has 4 + & 4 - DC ports, plus 2 mppt(2) ports.
Since the far left array gets shaded first, would I hook up the DC wiring to...
<--THIIS is a cut/paste of the Specs required by the utility
With the 2-2-2-4 wiring, would I need a "3 Pole" switch? Again, need an OUTDOOR rated switch
what would you recommend? Probably need something sizable enough to be able to 'fit' all of the 2 ga wiring (aluminum)
How would splice the indoor to outdoor wiring? Wire nuts?
The Inverter output is 47.5 amps. Would I use the 100 amp fuses or go down to 60 amps?
The Safety Switch is a Siemens GF223NR
Also, what fuse class to use: H, K or R?
