With the 15k, if you press the Emergency Stop button, you lose all power to the load panel?

Hello, I've been searching for the "best" way to enable RSD with the Tigo Optimizers and EPO with the Sol-Ark 15k. From what I've seen, the best method seems to be using pins 15 & 16 on the Sol Ark to drive a relay at the Tigo CCA. After that, there have been two methods. 1. Relay NC...

Everything I found was no more than 3 90's in a pull. I have a little less than 3. The final bend to get on the roof is about 67°. I have an LB at each end. This shows a little better. (And also my first ever conduit bend so I didn't think I did too bad.)

I just went through the same thing and just wrapped around the roof. If I ever change my mind, it's easy to remove.

Very nice! Have any pics of your sled in action?

Finished my 3rd battery pack!

I got the BMS and Sol-Ark talking with the BMS in parallel. It turned out to be super easy, just set the master dipswitch to 0 and the first to 1 and it worked. It reports up to the Sol-Ark everything that's needed. I got my roof mounted transition panel and the conduit up to it ran but I...

Well that wasn't a fun process but it's done! The ATS is now my primary N-G bonding point and all the grounds have been separated from the neutrals at my main panel. At the same time, pulled new 2/0 copper to my inverter and I would say the cleaning up the N/G issue took longer than pulling...

2nd battery pack up and running! Got the JK BMS and the Sol-Ark to talk over CAN. Still need to figure out how to get the BMS's to talk in Parallel but I can actually test it now.

I tested last night and got my JK talking to the Sol-Ark 15k. A straight through cable would have probably worked but I swapped one pin for the GND connection.

Thanks! That explains better why they counted above 8 now.

Thanks for posting this! I'm just getting ready to wire my JKBMS up to my Sol-Ark and this is great information to have.

I ditched my 3D printed face plates and used some a guy in town laser cut for me. They turned out awesome!!!

It's been terrible! The only days it turns out to be nice, it shows rain a few days ahead so I schedule something else. I'm about 1.5 hrs south of you! Thanks from 45814!

So far I'm pretty impressed with the 15k, it's been easy to work with so far. Saturday is supposed to be nice so I'm hoping to finish up getting my mounting rails on the roof and start working on some of the wiring. I'm really looking forward to throwing some PV power at the Sol-Ark.

Yep, it's the 2601-3S-95. The thing was expensive. I ended up putting on cinder blocks as well to elevate it in the room. We have our water treatment in the same room so I wanted to give it a little extra safety factor.

I've not posted much lately because I've been spending all my free time on my build. The weather has been terrible so getting on the roof to install the mounts has been a pain but I've made a lot of progress on the batteries. I have my first battery pack assembled and the BMS works! Got the...

The plot thickens a bit... I ran my new ground rods already and am going to hook them to my main for a total of 4 rods. I looked a little more closely at the grounding of the ATS and it has wires going to the ground lugs but none of them connect to anything grounded! There is a large ground...

There should be 64, that's what I ordered! I haven't opened the 2nd crate yet. My work bench isn't big enough to fit everything. The JK BMS came since the batteries so I've been working on some design ideas. I sent off to a metal fabricator to see if they could make a face plate that I...

18650 Battery Store (https://www.18650batterystore.com/products/eve-lf280k) The shipping was expensive but they arrived in under 2 weeks from the time I ordered them.

Hello Everyone! I'm working on my first solar install / design and wanted a place to document it. I've got about 3/4 of my parts in and am eager to get started. Parts Overview - Inverter: Sol-Ark 15k Battery: Custom 4 x 16S EVE LF280k with JK BMS battery packs Panels: 54 Q.PEAK DUO BLK-G6+...

My batteries came yesterday!

The factory installed wire is large, at least a #6 but I didn't look that closely. I'll work towards removing the N-G bond on my main panel. I'm adding more ground rods to my installation so I'll make sure the ATS has a good ground as well. They have a larger green coated wire that...

My inverter came today! Woohooo!! 😁

Yes, it's got a disconnect. My panel does have a few shared ground/neutral bars. Thankfully most of my breakers are GFCI/AFCI so most of the neutrals are wired there.

There's a basic idea of it. Basically the ATS has a factory installed N-G bond that I believe should be removed. My main panel has the N-G Bond that I think should be kept.

I just had a thought and it's not something I've researched. Would it be better to have 9 panels with one being partially shaded occasionally or 8 panels?

Thanks for the responses! I'm 100% DIY on this. Doing it for the fun, cut my electric bill, and provide some grid independence if needed. That's why I was wondering about the grouping. The 2 sets of sides will be on 1 MPPT then the main roof section on the other MTTPs. I'm also looking...

Well, truth be told, I left out part of the build. I've got 54 panels in total which maxes out my inverter for my panels. The last set will be an E/W string. I guess I could just add an extra panel to that side and steal one from the other array. Here's more of a full picture: I'm going...

Thanks! Your assumption about the top is north is correct. There's a little chance of shade across everything. The bottom row of panels will get hit the worst. The tree that's in question will most likely get a hair cut if that happens. My gut feeling was the 3x3 array.

Hi Everyone, Getting into the weeds on my new solar build and I've got a question. I'm going to end up with 36 solar panels on my roof. They'll be grouped into 4 strings of 9 panels in series. This complies with my requirements from the panels and sol-ark 15k. My question is, does it matter...

Hello Everyone, I'm in the process of ordering everything for my first solar install. I'm a DIY kinda guy so I'm doing nearly everything myself. A year or so ago, I had the generator that came with my house replaced. It was a "half house" and I upgraded to a "whole house." The main...

That looks like a TON of fun!!! :D

Well, I decided to just rip the bandaid off. I did some quick measurements and the panels I've been watching at Santan fit my roof nicely in 3 rows so I ordered them today! Model: Q.PEAK DUO BLK-G6+ 340W

Oh, I forgot to address the RDS item. Both the optimizers I'm looking at have RSD built in. That's part of the reason I'm looking at adding them.
