Compete Enphase System Wiring
If you’re trying to complete the Enphase University Courses, but having a hard time understanding without enough hands on experience , these video might help. Some minor verbiage & description is incorrect but the wiring is correct for this Enphase system that includes:
-Rapid Shut Down Switch
-Enphase System Controller
-Enphase Battery
-Enphase Combiner
Please watch the rest of the videos to REALLY learn from my mistakes!
Enphase Control Wiring Troubleshooting
Thanks @harveywoodsllc for diagnosing this minor Enphase control wiring that prevented the system from commission.
The control wiring terminals have to be installed perfectly in the terminal lugs to ensure Enphase System Controller and Enphase Combiner can communicate properly.

Another conduit between the trough and the Enphase System Controller would have been really helpful in this installation.
I set my 2” PVC conduits to be directly below the 4/0 line and load wiring, but there was plenty of room between them to have added another conduit.

Not such a big issue but would have saved me a minute or two if I had remembered that little segment of the Enphase University training!
Enphase System Controller with 200 amp Service Neutral / Ground Lug / collar strap Eaton GE
THIS was the biggest System Controller issue I encountered. This little part set the project back 2 days!
This solar installation is a whole home back up for a 200 amp service. Almost no Google search or Enphase university video course taught a system using a 200 amp service.
The issue I ran into was that the 2/0 ground in a 200 amp rated 4/0 SER cable did not fit on the ground bar! It’s a pretty ridiculous and a MAJOR design flaw of the Enphase System Controller! The parts kit also does not include a ground lug or collar strap for 2/0!
Everything in the Enphase System Controller is Eaton (or Siemens) compatible. I purchased every Eaton and Siemens (and even Square D) ground lug kit I could find, but none worked!
Luckily, I knew about the GE ground lug kit so I bought that out of desperation while waiting for Enphase customer service and the dealer to get back to us.
I added pics and the specific name of the kit to the start and end of the video!
I’ll never do another Enphase System Controller with whole home back up again without it!
Enphase Solar Installation Mistakes and Lessons Learned @harveywoodsllc
I’m posting this video to help anyone with some practical application installing Enphase Solar with a 200 amp service, Enphase Battery, Enphase System Combiner and System Controller.
(I misspoke a couple of times on here, but the lessons learned from installing this system would have been helpful if I’d seen them before!)
There are a couple of other Enphase lessons learned videos too! Watch them all to be sure your installation (not just the wiring) goes smoothly.
Foreign Plug Solved!
This client had received a teapot from China and wanted to be able to use it here. We were able to find her voltage converter to safely get the appliance working. 
This was definitely an unusual and interesting little project. We were really grateful to be able to help this client!
