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...
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...
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+...
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...
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
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...
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.
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...
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.
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.
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...
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...
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.
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...
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...
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...
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.
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...
I've got a 2400sq ft house that was setup for traditional power. I got tired of $300-$600/m electric bills so I decided to take matters into my own hands. I have a terrible tendency to upgrade right after finishing something so I thought I better basically start with full panels and decent...
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!
Hello. I ended up wiring a relay powered from the Sol-Ark 15/16 pins to the Tigo AUX port. I figured this will give me the best config as my IT equipment is on a UPS so if the Tigo is able to send a note, I should get an alert if someone ever pushes the EPO/RSD button.
The Aux port is...
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?
