A lot of time has passed since I first started this journey. I am reminded of a quote from Thomas Edison. "Genius is 1 percent inspiration, 99 percent perspiration".

Here are some lessons learned from this project:

1. Use this forum for information. From a distance everything seems easy, however the closer you get to the details, the more complicated things become.

2. Feel free to get critiques from other users. A double, triple check of a design is helpful for us beginners since we are walking a new path. Admittedly I had to swallow my own pride on more than one occasion. It was worthwhile however because the recommendations were priceless towards the ultimate safety of my project.

3. Make sure to get the right sized lugs. It is tempting to just buy for wire size when you are buying from a supplier. I made this mistake, not knowing better at the time. A properly sized lug will maximize a proper fit so the lug can make a proper connection.

4. Check and check again. Step away from the project to allow a fresh view the next time you look at it. It is amazing the things I have missed in the first inspection.

5. This journey has taken a LOT longer than originally planned. It is easy to look at a few videos from an experienced user and think things will move quickly. My mechanic is very skilled at what he does. When he makes a repair, he makes it easy. That is due to experience. Many of us are at the beginning of this journey. It is natural to make mistakes. The important thing is to learn from these mistakes, thus improving our skill set. I have learned a ton during this process.

6. Look forward to the new tools you will obtain for this project. Having said that, there is professional grade and project grade. It is tempting to pick to pick up a much more expensive tool. Often there is a less expensive option available that will enable you to safely complete the task.

7. Spend the money for quality components. A lot has been said in other threads on this. Having said that, make sure to invest in quality wire, fuses and components. It helps one sleep better at night.

I am opening this to others who might want to share things they have learned from this process.

Hope you have a good day.

One MAIN Ingredient that far too many lack when approaching such projects, and that is Patience...
Listen to and HEAR the advice from people who are seasoned builders/assemblers with a posted track history, showing their builds & setup and such. There are many giving (passing on) advice who haven't even got a system so take all things with a grain of skepticism and look for their own "About My System / My Solar Build" pages which show & explain what the 'advisor' has and has done.

@JJJJ remember to make a post of your own to show your build & assembly which people do find quite helpful when they are considering their options.
 
@Steve_S , thanks for the push. I was struggling trying to figure out a design on how to add my hybrid inverters with batteries to my existing SMA system, without having to purchase a new solar array to charge the batteries. I wanted to use the SMA inverters to do that instead.

I finally came up with a design that should work, while also enabling generator backup. Attached is the AC side drawing in case someone else is could use it.

I agree with all of this! It has been quite an experience for me so far, and almost all positive experiences, mixed with occasional frustrations. A large part of the positivity has been due to this forum and the patient folks here who are so generous with their time and experience. I could add a few things to your list but I'll just pick one thing to add for now -

8. Wire lube is your friend! :ROFLMAO:

Snickers, I've been around doing this stuff for quite a while now and I believe that the "Valley of Despair" segment of the learning curve average is between 3 to 6 months before getting past it. I feel the single biggest Hurdle to get past is the use of the Terminology and the Context as it relates to DC Systems as opposed to AC Systems and of course this is not made easy because both AC & DC use identical terms but the result / outcome is not necessarily the same. I can't address those poor folks who look at these Battery Systems in the same light as if they are sticking a bunch of AA batteries together. Nothing a 500A ZOT won't correct (one way or another) ;-) .
 
Well written as I have gone from knowing nothing to putting together a system I'm hoping to be proud of. hopefully smoke test will be in a couple of days.

I did tire of the absolutes without reasoning. I'll question everything as I'm learning, it was a process that served me well in my career. From where I am at today, I'd probably have totally skipped the factory installed solar, maybe not ripping out one panel and installing two more. Roof unfortunately looks like swiss cheese, but I am comfortable with the hole repairs I did. Had I not done it that way, then I may not have taken on this larger replacement expansion project.
