    Another N-G bonding thread.

    Starting a new thread because I created confusion by hijacking this thread: https://diysolarforum.com/threads/n-g-bonding.80429 In that thread I posted photos of my meter set-up: https://diysolarforum.com/threads/n-g-bonding.80429/post-1032841 I apologize for creating confusion. A few folks...

    N-G Bonding

    Good point. These are from a few years ago. 100A breaker behind the flap. I've been told there's a neutral-ground bond in the non-homeowner section that is above the terminal blocks.

    N-G Bonding

    So to be perfectly clear, the N/G bond should be at the meter base at my pole and every other panel in the system should be not bonded; regardless of whether there is 3 or 4 conductors running to that panel.

    N-G Bonding

    I'm currently building up my own system and am confused by this. I have a power pole in my yard, with a transformer at the top and a meter base at the bottom. Below the meter is where I, the homeowner, can take power. I had two runs come off this, one to the house, and one to the shop. The...

    Solar Assistant - data logger

    I had to do some monkeying around with pam and /etc/ssh/sshd_config when I did mine. I don't remember exactly what I did to make it work though. Fortunately, the latest version of Solar Assistant (64bit) has a menu option to enable ssh access: 1) Go to...

    Sol-Ark new optimizer

    You have to root the CCA. That apparently used to be easy to do but a firmware update that Tigo pushed out closed that hole. Now you have to open the CCA and solder to the UART pins and hack the u-boot environment. I'm struggling with 'do I want RSD+Optimizers and thus give my money to a...

    Sol-Ark new optimizer

    To be fair, it may not be Sol-Ark's fault. It looks like they were planning on just integrating this company's product: https://enteligent.com/products/enteligent%E2%84%A2-nmax-optimizers-m500a1 but previous versions of the website had pricing and even had some videos from the CEO explaining...

    Sol-Ark new optimizer

    People are reverse engineering the firmware on the Tigo CCA and have figured out how to get their data off the device without using the 'cloud'. Tigo keeps pushing firmware updates to close the holes. https://github.com/rp-/tigo-exporter/tree/master

    Sol-Ark new optimizer

    Advertised "1 minute data resolution" but they've been having trouble with their servers for apparently going on 3 yrs now and they keep promising they're updating their server infrastructure and keep pushing the date further to the right. So even people who are paying for the cloud service...

    Solar Assistant - data logger

    I only just started with SA myself the other day. I discovered that SA won't correctly talk to my Shoto SDA10-48100 batteries. I sent mail into their 'Contact us' address but after getting root access, I note that the box is pretty unhappy. The circuits_uart library seems to be leaking and...

    About to buy Sol-Ark 15k. RSD and Optimizer questions..

    In order to pass inspection, I need RSD. It's not clear to me that RSD is possible in a 'Blind Deployment'. Reading the german thread referenced in the github discussion, it would seem that when someone discovers how to access data from the local CCA, then Tigo sends out a firmware update...

    About to buy Sol-Ark 15k. RSD and Optimizer questions..

    That's what I'm reading, yes. It looks like the Tigo optimizer does some processing in their 'cloud' to improve the optimization (except when the cloud is largely unavailable for 6+ months). But the RSD functionality is still there but requires their CCA to be present in order to work. Given...

    Does an RSD need a cloud platform? I didn't see anything about an APSmart 'cloud platform' when I was pricing it out.

    About to buy Sol-Ark 15k. RSD and Optimizer questions..

    They claim to be doing some sort of 'international service upgrade' and are saying all server problems should be fixed then but offered no timeline.

    DC to DC wiring with RSD/Optimizer to a Sol-Ark

    Just curious if you managed to actually buy these Enteligent things? Looks like they've gone unobtainium?

    About to buy Sol-Ark 15k. RSD and Optimizer questions..

    The more I dig into this Tigo thing, the more I realize they're a company I don't want to do business with. I was literally about to punch the 'checkout' button on a $2300 order when I decided to look into how I was going to get information out of these things. Turns out it's complicated and...

    About to buy Sol-Ark 15k. RSD and Optimizer questions..

    Since it isn't explicitely noted, I assume people are putting a small relay on pins 15/16 to switch the power from the Tigo power supply to the Tigo transmitter?

    About to buy Sol-Ark 15k. RSD and Optimizer questions..

    Someone needs to tell the Sol-Ark technical support person I spoke with yesterday because he had no idea when and didn't think it was going to be imminent or even soon. Also the Sol-Ark page (which was last modified on Jan 16/2024) says Q4 so I presume that means Q4-2024...

    About to buy Sol-Ark 15k. RSD and Optimizer questions..

    I called Sol-ark tech support and got the goods. The TX is a separate board that's not even available yet because it's meant to pair with the Sol-Ark optimizers which are also not available. So the Tigo optimizers/RSD stuff operates completely separately and just gets wired in to the...

    About to buy Sol-Ark 15k. RSD and Optimizer questions..

    I wondered the same. This post https://diysolarforum.com/threads/sol-ark-new-optimizer.54308/post-807966 says new ones should come with the TX built in but I don't know if @DIYrich is saying "new ones come with" or if he's giving a suggestion to Sol-Ark to include them with new units.

    About to buy Sol-Ark 15k. RSD and Optimizer questions..

    Thanks. So I think you're saying the TX 15K-A is built-in to the Sol-Ark, but I need to buy a seperate Tigo TAP and CCA?

    About to buy Sol-Ark 15k. RSD and Optimizer questions..

    Thanks. I was not sure if the Sol-Ark RSD initiator would know how to talk to a Solar Edge optimizer. So I guess you've confirmed the answer is 'no'. So I guess it's Tigo for me because the Sol-Ark O900-80V isn't available until Q4 which is too long to wait. Now I just need to figure out...

    About to buy a Sol-Ark 15k and 3x9 Longi 515w panels. Some parts of my strings might experience shading during the day during some seasons and I have an RSD requirement since they're roof-top. My ex-electrician recommended Solar Edge S505 optimizers but before going ahead with my order, I...

    New system layout issues / q's.

    Thought I'd post an update. I know this thread has probably sunk into the depths of history but I've now started on this project. I decided to bite the bullet and dig the trench and rewire the power distribution from the pole into the shed attached to my shop. I've also decided to go with a...

    Narada 48npfc100 closed loop to Sol-Ark 15k

    I'm still in the "read and learn" phase of my build. I've also met with my power company to discuss reconfiguring my pole and so forth. Planning some trenching. Applying for gov't grants. etc. I've managed to acquire a handful of Narada 48npfc100 batteries previously from telecom use so I...

    Today's Stupid Question: Is it Safe to Drink the Water That My A/C Unit Emits from De-humidifying?

    Anecdotally, one of my employees is a feral cat and she drinks the condensate from a window air-conditioner in my shop (because she doesn't want to come in and drink the water I put out for her I guess). She's been with us almost 15 years and refuses to get eaten by predators. Some might...

    Can you buy EG4 equipment without doing thru signature solar?

    That's why I'm in this thread. How "the same"? Is the hardware/firmware/software the same? I'm still in the "reading a lot and applying for permits" phase of my project and I didn't like how SS behaved in the 'other thread'. I was on 'Team EG4 18kpv' until I read that thread.

    New system layout issues / q's.

    I just heard back from mppsolar. The generator input / 2nd AC-Output is not bidirectional so that means I can't use it, in my scenario.

    New system layout issues / q's.

    You're a real buzzkill. Anyone ever tell you that? ? Is watts247 one of the diysolarforum suppliers? I was told by PLin@mppsolar to order direct from them (because I'm in Canada apparently).

    New system layout issues / q's.

    I asked mppsolar for information a few days ago and just received a response that they have an LVX6048WP with a separate generator input that can also be an AC Output. https://www.mppsolar.com/v3/catalogs/LVX6048WP.pdf ... I'll see if I can find the manual. I can get 3 of them for the...

    New system layout issues / q's.

    From another thread here, it looks like I can get a Sol Ark 12k for $6225 USD plus shipping. Maybe have it shipped to a buddy near Seattle and he can bring it with him on one of his trips. https://tandem-solar-systems.com/product/sol-ark-sa-12k-pre-wired-hybrid-inverter-system/

    New system layout issues / q's.

    "poco"? But I see. So essentially the inverter is just a UPS. When the grid is active, it doesn't supply power. I guess I lose the ability to add on a bunch of PV and shaving or what have you.

    New system layout issues / q's.

    Yes. I'd have to daylight the existing one at each end first and I already know the path of the existing.

    New system layout issues / q's.

    $11k CAD for a Sol Ark 12k. If I decided that digging a trench from garage panel to pole is in the realm of possibility; does that radically change the equation? I can use my extra conduit space to get from where the generator is now to the garage panel (annotated drone image attached, South...
