Our grid tied Solar system has been up and running for 8 months now and we're way ahead of the curve on selling juice back to the utility vs. what we consume. I have an insulated shop, 10' x 40' (400 sq ft) with 8' ceilings. We'd like to put in a 240v Heater. We don't need to keep this...

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...

Finally got our 13.2 KW system up and running. Along with washer/dryer, oven, etc., this spring and summer, we'll be running a 5 hp irrigation pump 2-3 times a week (usually 12 hours on a set). Our utility is Rocky Mountain/Pacificorp and their program buys up our unused energy produced. We...

11.4-1 Fronius Primo has been averaging 249 to 259 volts AC output production. Is this an issue and if so...how can it be corrected? Not sure if it's an adjustment to be made internally with Inverter but Fronius manual doesn't seem to address this issue

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...

We're required to have this Label yet absolutely no "Label Map" addresses or shows this Label Where does it go?

I read that it's best to undersize Inverters a bit regarding the panel wattage production. as I read it, inverters are more efficient when pushed to their max. Example: Fronius Primo 11.4 grid tie Inverter. Rated for 11.4 kw and operates in a range from 9.1 kw to 13.7 kw. Our Array consists of...

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?

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...

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 -...

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...

I also had posted this on the general forum. This grid tied Array consists of 9 panels and I want to connect them into a 1 string, In-Series Is the attached diagram represent the correct wiring? THNX

Ok, getting closer to completing our Grid Tie project. Our Array consists of 33 - 400w panels wired in series. Originally, the plan was for 3 - 11 panel arrays but due to a change in plan (another Inverter selected), we needed 4 arrays. NOTE: the Inverter has 4 DC + & - inputs So, we have 3 - 8...

Alright - Panels Installed...DC Wiring connected to the Inverter...the 2-2-2-4 cable is buried and connected to the 240v Shut-off switch box. Now, the AC power needs to go from Shut-Off box to the Grid. Our Utility requires that a licensed Electrician makes the AC cable connection to the...

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?

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...

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?

Most seem to have lugs that max out at accepting 3 ga wire. Is there a switch out there that will accommodate 2 gauge or can we somehow 'cheat' and make a 2 ga fit into a 3 ga. lug?

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...

Grid Tie Inverter: 240v and 47.5 amps length of AC cable run: 230' Cable used: 2-2-2-4 (2 ga. Aluminum) My calculations show a 2.9% voltage drop, just squeezing under the 3% threshold. Am I correct?

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...

Will be running underground rated wire from Grid tie Inverter to main distribution box. We'd need a 4-strand (2 loads, 1 neutral and 1 ground). What is this wire called? Also, could the ground wire be of a thinner gauge then the 240v wiring? If so, we'd need a 3-strand wire and run seperate...

I posted this earlier, but will just start over with some added facts Our system will be a 13.2 KW grid tie, using a Fronius 11.4 Inverter. The panels will be mounted on a shed. The single phase AC 220v run from the Inverter to the distribution box will be 275 feet (100' inside the shed, then...

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...
