Shop system build- Out of the box

[Zwy]

Things have been coming together on the shop system build with 114 Kwh of LFP batteries, 2 SRNE 10Kw ASP inverters. Using a larger Hoffman electrical cabinet similar to the one in my house system. Array was put up this summer consisting of 24 370W NE Solar panels on a tornado damaged MT Solar mount. Originally planned for 74 Kwh but as things progressed the battery bank was upped to 114 Kwh. Originally started early summer but had the array to put up and finally get around to finishing battery bank and inverter installation.

Almost forgot, everytime I say "Later", you have to take a drink.

Watching it now. Given the time of day, I'm going to take a sip of coffee instead.

Kinda wish I'd punched mine out, looks like it made it easier. Was worried about the battery terminal studs, in particular. That PV opening though, why that's not a circle...uuggghgh.

I know what I'll be doing after my 10AM meeting. Wish I had some Bourbon to add to the coffee.

That oblong hole with the switch located there sure is something. @42OhmsPA and I were discussing the battery terminals and what a pain it was getting the cable lugs on the studs. I don't how you did it with 3/4" EMT.

I need to make a correction to my post on the 3/4 EMT. I did try originally, and it technically worked with 2/0, but there was no free air at all. So, my battery cable is currently in free air from the trough to inverter, and down to the Victron Power-In. I want to clean that up at some point, but I have several more pressing things I need to do right now.

I really like how nice an neat everything is.

Great tips on lining up the conduit, sliding the trough up, etc. Wish your video was out before I figured it out during my install. Most of it is pretty self explanatory but watching someone else do it will definitely help others tremendously.

I need to make it a priority to find a used cabinet so I can make everything "portable".

If you haven't already don't forget to check all the factory connections on the other side of the terminals, I was able to snug mine up a bit more. I never did check my ASF and didn't have any issues but glad I checked the ASPs.

After seeing you and @agtcovert using the "blue bus" I just might have to get one myself, probably paint it a different color though

 

[Zwy]

I like a little color now and then.

Yes, I double check everything, you will see in the next part how I am very particular when it comes to connections.

The way I built this, it could always be moved easily if someone comes and offers me $3 million for my acreage but doesn't want the shop solar system.

My house I ran 2/0 thru 3/4" EMT, it worked fine but the cable lug had to be crimped on after the cable was run thru the conduit if I remember right.

1" EMT is no problem, slides right thru with the cable lug attached.

That was the primary issue I had, the lug wouldn't really fit, and I wasn't comfortable trying to crimp while basically holding it in the air. If I had a snazzy power crimper, perhaps. Was also worried about free air + heat on those cables, since I do charge from the inverters currently.

I may go back on the batteries and PV and get those in conduit after seeing what you did. Your punch looks about the same as mine.

Part 2. It's coming along well, biggest thing is having everything needed for supplies and components.

You have Part 2 to watch on a Friday night, enjoy.

Excellent work.
Learning a lot of tips and tricks, thank you.

I noticed that when editing the saved posts that it won't show in the new posts or notify other members. One of those glitches if you want each video in the series to be available for viewing without having to search thru other posts. I'll workaround it.

i was confused at first... then it hit me... Zwy was at it again trying to confuse me.

Running the 1.25" conduit from panel to inverters. This is what 12 years of dirt and dust looks like when you start moving stuff out of the way.




A side benefit is getting the walls and floor cleaned for once. I did move that pallet rack, I used the USMC method. Danny knows what method that is.

Part 3 is now done and up, getting closer.

 

[Zwy]

Part 4 is now done. Part 5 will be testing and other additions to the system.

Part 5

Working well since startup, I've been running over 200 Kwh of PV per week thru the inverters.
