Clear skies 93% blocked by the moon. Output dropped to 440watts would typically be 6000 at that time of day.

Been awhile since I've done industrial work with Delta services but do remember if you have a high leg a plain old 120/240 breaker won't work for the high leg. I let Mr. google help me remember. So not all multi-pole breakers are rated for 240volts...

You are 100% correct. Over the years when asked to do a side job and the signs of a "handyman" doing electrician work there are obvious I turn it down. (side note if you follow codes and install in a neat and workman like manner, I'd never be able to tell)

138 responses later think you helped him or have him so confused he has no idea what to do? Like someone above posted really don't care if he lets the smoke out of the box, but he does have a small child to think of.

Not in the least just look at the wide variety of answers thrown out there from the armchair DIYers. Every response should have first asked and received more information before making their wild a** guess based on what they think they know. It's called the Dunning-Kruger Effect. End of rant

Just a quick follow-up to my advice I offered. I fed my family working as an electrician giving me enough knowledge to know I can't walk you through this online and be 100% certain of your family's safety. To those posting help do you feed your family doing electrical work? or is this a hobby...

SAVE YOUR DAUGHTERS LIFE!!!! DO NOT TRY AND FIX THIS WITH HELP FROM THE INTERNET!!!! I'm a retired master electrician. I've tried troubleshooting over the phone with halfway knowledgeable Maintenace workers and it just doesn't work!! Online IMPOSSIBLE!!! Please hire a bonified...

If you didn't show it clearly, how would they know? They are not in the business of knowing what options are provided with the equipment you buy. Show it correctly on a one-line or hire someone to draw it. Just my 2 cents after 40 years of furnishing one-line drawings in the permitting process.

If it's new unopened box at 50% off from a person I'd take my chances otherwise open box from a person 70-75% off. It is 2 years old........

Is that your total cost per KW including delivery and taxes of 9 cents? You can get that rate cut to 4.5 cents with split metering? Get a propane generator for backup and forget solar. You will not pay off your investment for 20-25 years. Solar makes "cents" for folks in California paying...

My SREC payment is based only on production. https://illinoisshines.com/faqs/

If you want to follow the code for a 50Amp breaker use #6. NEC Article 110.14C(1) will explain.

I just read the the 2023 NEC sec 690.12 and only 2 exceptions do not require RSD. However as you mentioned if you go to the expense of meeting UL 3741 standards such as the Ironridge system with the inverters they spec. it can be done...

You'll need something if it's a roof mount to shutdown each panel. Either optimizers or Tigo units...........

Just following eating popcorn while the OP seeks advice on a commercial scale system on a DIY site.......

Reason to use smaller panels on a roof is handling them.

Is this just a grid tied only system? Or are they also quoting batteries which for most people is a TOTAL waste of money.

You have no idea what you are doing and yes a "grid tied" inverter can kill a lineman when installed by an uneducated DIYer. 38 year member of IBEW

https://www.ironridge.com/ Using them was money well spent for the ease of installing my first DIY solar system.

This popped up on my new posts, so I'll answer. We would survive as long a time period as my great grand father did, and my great great grandfather before him...........and his ............so on and so on............

Won't matter how many layers you use to make your tin foil hat when the "big one" hits again. https://www.history.com/news/a-perfect-solar-superstorm-the-1859-carrington-event

I'm guessing 60-70 thousand? Do you have that many power outages to justify it? Couple things to look at. What are your net metering rates? I use my utility as my battery because my rates are 1 to 1. How many RECs will you get if any? My RECs paid for my system. I've had one power outage at...

/\ /\ /\ X2!! with 90% falling under #4

No fuse the panels will only produce what they are designed to.

How thick is the rigid insulation on top of the roof boards?

Post #3 is your correct answer.

Tough to hide a solar installation from the various map programs that provide a bird's eye view. As to fines? Depends on your reaction to getting caught. Might be a few bucks, might be tear it all down and pay $$$.

Yes sounds like the wrong CT size was programmed in. My Solar Edge was DIY BUT, I'm a master Electrician so was able to get all the installer info from the solar edge site as if I was an installer even though this was a one-time solar install for me. I used the "setApp" smart phone app to set...

There is some simple commissioning to be done to get it up and running. I used a Solar Edge app on my smartphone called "setapp". Check out the app see if it allows you to open and explore its features. Only done one install so I'm not well versed in what you can/can't do as a DIYer. I was...

The LB you linked to will work This is the type of fitting you need to look for. Usually they have a blue mark of some type so the inspector knows it's not a standard compression fitting...

X2!!! No worries if you miss if you're using a quality roof mount system with large flashing mounts, they will cover any holes. something like this: https://www.ironridge.com/component/flashfoot2/

Why is there so much dust on them? Can you take another picture that shows the entire panel?

depending how many panels you wire in series you will have less loss once your DC voltage is greater than the 240V ac you're sending back now. Quite possible if your inverter allows it to send back 480V DC, again depending how many panels are in series and the DC input voltage limits of the...

Thanks for posting the label pictures. Maximum wattage those inverters put out is 290watts. VA is the same as watts for purposes of this post.
