    I ditched my 3D printed face plates and used some a guy in town laser cut for me. They turned out awesome!!!
  • Post in thread: NW OH DIY Roof Mount Solar

    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...
  • Post in thread: NW OH DIY Roof Mount Solar

    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...

    I'm pretty happy with the results so far! I've used very very little grid power in the last 30 days.
  • Post in thread: Multiple N-G Bonds - Want to fix

    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...

    My batteries came yesterday!
  • Post in thread: NW OH DIY Roof Mount Solar

    Right now I'm running with it grid connected and zero export. At the rate I've been going, I doubt I'd export more than 3-10kwh a day while the AC is running. It's almost noon and my batteries are at 57% and getting about 11kwh right now. I have an application in to allow me to sell back...

    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+...

    No, it's been in the low to mid 70's most of last week, getting into the low 60's at night so we had the windows open. I ran it yesterday when I got those numbers. I use around 60-70kwh most days and yesterday was 90kwh. My batteries are at 40% right now and it's supposed to be cloudy this...
  • Post in thread: NW OH DIY Roof Mount Solar

    It's basically done! I still have to wait for my interconnect but I'm able to generate power and run off my batteries. Used a forklift to raise the panels over the roofline so we didn't have to carry them back and forth. I even got the 2 wire start hooked up to my generator. Just need to do...

    My inverter came today! Woohooo!! 😁
  • Post in thread: How to pick solar panels?

    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
  • Post in thread: NW OH DIY Roof Mount Solar

    I looked when it started and I didn't see any grid spikes in the UI, it did pull a little extra from the battery it appears. I'm not 100% sure how it works with the passthrough but so far, aside from very little grid power being used, I haven't noticed anything. We've had 2 power outages so...

    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.
  • Post in thread: Solar with a automatic transfer panel for Generator already installed.

    I just completed an install with an ATS. I left it in place and converted my generator to be 2-wire start. In the event the grid goes down, my ATS kicks in then when the sol-ark needs extra power, it can use the 2-wire start to fire up the generator. I haven't fully tested it yet but we had...

    Finished my 3rd battery pack!
  • Post in thread: NW OH DIY Roof Mount Solar

    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.
  • Post in thread: Multiple N-G Bonds - Want to fix

    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...

    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.
  • Post in thread: NW OH DIY Roof Mount Solar

    I bought 56 just in case there were any issues but all 54 are installed on the roof. I've hit higher production than I thought I would with 8 total panels facing E / W. (4 each) My main roof section has 36 panels, then 9 on each side. 5 S facing and 4 E/W depending on the side. I'm not...
  • Post in thread: New helical wind turbine fence concept

    If it's 6kwh / day, you'd still generate 3kwh during hours when the sun is down. That'd help my batteries a little at night. They don't mention what kind of wind speeds they'd need to generate that however.
  • Post in thread: NW OH DIY Roof Mount Solar

    Thanks! I really wanted to be done by 5/15 and I was able to do it! Yep, I used the JK Inverter BMS that has COM built in. It seems to be working well. Once I got the dip switches set, I set the com protocol to pylontech and plugged it in, then it just worked. There has only been a couple...
  • Post in thread: Hello From NW Ohio

    Thanks! We're about an hour or so south of Toledo. From what I understand, the epicenter is supposed to be in Forest and I'm about 25 min from there. We've only heard a little about it but from what I've heard, people said it'll be a big deal.
  • Post in thread: NW OH DIY Roof Mount Solar

    Since the pool is running, they run to about 36% every night. A couple nights they got down to 20% which is where my TOU settings tell it to stop and run off grid. I run as much as my house as I can off the system right now. My average use is about 2.6kwh constant with spikes to 7.7kwh...
  • Post in thread: NW OH DIY Roof Mount Solar

    We try to use our clothesline whenever possible but not much planning goes into when laundry gets done vs the weather. Sounds like you need to upgrade your sub panel! :cool: I knew I'd be in a simialr boat if I started small so I just went for a maxed out single inverter right out of the...
  • Post in thread: South-Facing Solar Array Underperforming: Seeking Advice and Expansion Tips

    The optimizers are supposed to work without the TAP, I believe they call it blind mode or something like that. I believe your warranty/support changes if you run in that mode. I recently did a full install with the Tigo optimizers, tap and all. They seem to help. Is 5kWh over 87.4kWh worth...
  • Post in thread: Grouping Solar Panels

    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.
  • Post in thread: How to pick solar panels?

    First, thanks for all the replies!! My property is bordered on 3 sides by trees, then our front lawn (south facing) has a bunch of mature maples. I'm living in the house I grew up in so I saw them when they were planted. There are a few dead branches than I know I can thin out. From...
  • Post in thread: How to pick solar panels?

    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.
  • Post in thread: South-Facing Solar Array Underperforming: Seeking Advice and Expansion Tips

    They're about $50 ea, you could try it on a single panel and see if makes much of a difference. If not, I bet it would be fairly easy to resale.
