Here's one company which stocks some panels fairly close to you. They might transfer inventory also, IDK, https://a1solarstore.com/ I'm sure there's others in the NY/NJ area as well, it's been a while since I've looked.

I think the results might surprise you. With a constant load, you'll see it with a clamp comparing the top of your stack to the bottom. Please share your findings when you get a chance to look at it... Since it's easy to do, you might want to compare your findings to hooking them up on...

I guess I'll have to look again. Last time I checked, you couldn't get decent 280Ah Eve cells delivered for $100. If that's the case, I would consider building another 14kWh battery.

With everything you know now, what would you do if you were buying today?

It's not like those micro inverters are going to fill a landfill site, they're tiny LOL. My point was, the micro inverters and the software are obsolete, hardly anyone would mess with it. IMO, it's not worth hassling with the archaic stuff. Yes it's possible to patch things together to...

Thank you for clarifying my statement. Yes, obviously they can be hooded up this way, but you lose the ability to monitor and balance each individual cell in both banks. Kinda defeats the purpose...

Well one potential bonus from being off the grid, minimizing CME risks/exposure. But I get what you're saying, the SA inverters are extremely flexible and automate the process well.

Question for you guys... I know pushing voltage over max voltage from the panels will typically damage the inverter. But what about going over max amperage (in this case 12 amps)? I ran the numbers for my panels with 2 strings and came up with Isc (A)=12.86 and Imp (A)=11.94. More often than...

I'm assuming: panels ->SCC->batteries->inverter(s)->mains, so you're always going through your batteries at all times the inverter(s) running?

Wow, what an amazing turnaround! Congratulations Steve, we're glad to hear you're recovering so well!

TTT

Interesting, I believe that's significantly higher than what others have previously reported.

I have not looked myself, but I can tell you SolArk's tech service line is VERY helpful. I would recommend sending them an email or giving them a call to answer any questions you might have. They might not be cheap, but their CS/TS is amazing... Also, for the relatively small price...

I have a large driveway, that would offer a LOT of space for panels if they could be driven on, although I can see a lot of technical hurdles with this!

I was going to buy 16 Eve LF280K batteries, unless there's a better current recommendation for the money. I'll likely use the slow boat from China, assuming it's cheaper as I'm still waiting for an inverter. Who do you guys recommend contacting? Jenny, Amy, Amie etc... Price is important...

As long as you install and wire everything up correctly, that's about it. The only other caveat would be to make sure your wiring running from the PV panels to the house is large enough and the breaker/panel all have the capacity to handle the extra PV panels.

While on this topic, 1) Isn't the disconnect required to be exterior (and close to the meter, or is that optional), and 2) The disconnect doesn't have to be fused, correct? 3) Since N/G bonding typically takes place at the main panel, I'm assuming you mean to just feed the N/G ground on...

If the wiring is up to snuff as well, I'd say it looks as easy as just adding the two additional panels.

Definitely a loaded question with way too many variables! We have NG and wood heat. We can heat and cool (via MS system's) only the areas of our New England house which we chose to do so. Realistically, we can, and typically do, get by with <10kW/day. With that said, if I'm making the...

Has anyone come up with a good flexible busbar for the newer twin post terminals for use with cells under compression?

I'm not sure what the shipped price is on this upper pictured beefy looking busbar, but it looks like a nice piece! Tin coated would be ideal!

4s @ 150V is right at max, but once adjusted for temp you're likely over max V... which could likely smoke that expensive Delta Pro.

I just checked and the iQ7+ only goes up to 60V, the iQ7X (for 96 cell panels) goes up to 79.5V, still well below the adjusted VOC on my panels. My guess is you were using the iQ7X and either your panels had a lower VOC, or those micros are underrated. If the later, it might be worth a try...

I sent a private message to your in-box.

I have to agree. Those portable AIO setups are made to be generically convenient for stuff like camping and whatnot, but if this is for more of a permanent install for a residence, I would tend to think your money would be better spent on a system more tailored to your install... Likely getting...

Like (many?) others, I'm still a little fuzzy here regarding what's required and what's actually best practice. In my case, I have my main panel (with grounding rod nearby) at the house. I have a detached structure roughly 50'-75' away with my DC PV panels on top of it. In this case, does it...

Ordering batteries and likely a new inverter today. Mixed reviews on this one, where the Deye is proven, but price comes into play as well. If I go with this inverter, what active balancing BMS would you guys recommend going with? I'd like to get everything on order at this point...

I have a JK BMS, which I believe will handle a 17s configuration, and a Sol-Ark 15k, which I believe will handle up to 63V. While I already have 16 Eve 280Ah cells, is there any reason why I shouldn't order another cell and make it a 17s configuration? I'd rather have the extra capacity if...

This is where my interest is as well, maybe tying them in with a SA.

Use this calc, it will give you some great baseline info to work with for designing your system. https://pvwatts.nrel.gov/pvwatts.php

Looks like they got UL 1741 cert through SGS

Those SUN GTIL inverters are a good bang for the buck and fairly reliable given the price point. They only ship with one CT, so you'll need to get a second CT to limit split-phase 240V, and read up on how to connect the two CT's. https://www.ebay.com/itm/203684877124 You might want to consider...

Thank you, I'll make sure I save all my receipts for this project.

Keep in mind it takes a while for the micro inverters to do their self-tests and kick on once they see the grid. Depending on the MI, there can be a lengthy delay, which becomes problematic if your system cycles on and off frequently.

Remember, he ordered it last Oct. I doubt they are still shipping the Deye today.

Would there be any issues with AC coupling the 15K (through the GEN input) while tied to the grid and using zero export, or off grid, if batteries were installed and not at 100% SOC, with no DC coupled panels installed?

I ordered a set of 16, they were at my door in two days. Appeared unopened as from the factory, very well packed. I only inspected a few of the cells, but they looked excellent. Very reasonable price, great service and shipping, and solid looking product... I've had a very good experience...

Please take a video when you do this! Why not just use an ATS and a auto starting generator?

So don't bother DL the app, or is it needed for other reasons?

I also have looked at the 6548 inverters. Having an autotransformer certainly helps with imbalances (although one can be added to the SA product as well). The biggest thing that turned me off about those inverters is the very high idle/self consumption. Yes it can be overcome with adding...

Excellent! That should far exceed any off-grid load/surge I have today. TY for doing this testing. Interesting voltage output being reported by the inverter though, too bad you weren't able to confirm the reading with a clamp.

Welcome to the forum! You have already been given some good info. I would add that a common mistake (or possibly regret) I notice on here is not doing enough research BEFORE purchasing items. As Sunshine Eggo pointed out, you should fully understand your energy requirements and solar...

Understandable.

Not to get OT, but is does someone have a link for the rate being raised back up from 26% to 30%? TIA Edit: I did some reading and it looks like it's been pushed back up to 30% through 2032.

That's a good price for someone.

I don't recall off the top of my head, but I think it was north of 70W each (x2). And you are correct about the 12k being 60W. That difference really adds up quickly over time IMO.

It's certainly a little more complicated, but I would imagine it would improve the weak link (post connections) in these DIY batteries.

I do not believe it has that capability based on a conversation I had with one of their TS reps about a month or two ago. Hopefully someone else can verify.

I believe they spell out all the conditions in the spec sheet.
