You can get them, you'll just pay a LOT more for them, lol! But yes, these are well suited for our storage needs.

How far apart are these two locations? Have you spoken with SolArk about this? I think that would be my first suggestion. Their engineers provide excellent tech support.

Agreed, but even if these steps are taken, oxidation will still build over time creating a delta... Which is why I don't care for the idea of doing 2P.

That caught my attention as well! Granted I think he's videoing that in TX, basically outdoors on a warm day, so I'm sure the fans were trying to cool things down, but that was pretty loud.

Thank you for the clarification Keith.

My guess is the 15k will have a similar issue, but with a higher threshold. If this is a concern with either unit, add an autotransformer, but know it will drop your efficiency a little and increase the idle consumption.

Nice looking battery box for the Eve 280ah cells! So I'm assuming there's no compression on the batteries within this box?

That's how I read it as well, but this could be another potential Chinglish to English misunderstanding. It could certainty use some clarification on their part as 500V @ 12A is 6000W... x4 is 24kW, twice the 12kW max they also mention. In my case, I would have panels facing both SSE and...

On a related note... I'm going to be installing my 15k soon in the basement. All of the wiring will be coming down from a suspended ceiling, except the 48V battery/cables which will be on a shelf next to the SA. What's the recommend way to run the AC and high voltage DC wiring along the 1st...

That's insane for just AC and a pool pump! Getting the sunlight out of the house is an excellent and inexpensive start. You might want to also check to see if the pool pump is running longer than it needs to be. Baby steps!

Which makes me wonder, if not strongly consider if a micro (such as the iQ7X which is rated at 79.5V max) is artificially underrated. I spoke to one optimizer mfg and they told me their product is only rated to 80V to stay under for NEC RS requirements, but stated they have no problem up to...

I just entered some BS with a local (CT) address for the 16 cells: FedEx Ground® 2 business days$123.29 UPS® Ground$160.00 UPS 2nd Day Air® 2 business days$339.84 UPS Next Day Air Saver® 1 business day$666.26 A significant premium/cell shipped over the TX supplier, and a lot more over the...

Someone else offered $525 and he said no, but I'll float it by him again for you. Honestly the "micro" thread got me thinking about borrowing one and seeing if it will work with my 73V (85Voc) panels. I'm guessing the 79.5V max on them is only to stay within RSD requirements. Talking to...

He has a lot of intermittent load on that battery from his AC (as can be seen). Obviously the graph is auto-scaling so in your case, using far more electricity, it might look similar, but with a higher base load. Doing an energy audit would likely get you in the correct ballpark for battery...

"However, you would need grid sell selected when AC coupling on-grid, because we can't limit how much AC coupled power is being produced (either all or nothing)." I took that to mean either grid-zero will not work, or it's possibly not even an option in the set-up menu when AC coupling is used...

If you're willing to DIY, you might want to consider something like the panels you proposed, the Megarevo 8k inverter (handles up to 500V DC &12A MPPT x4, plus has CT's to limit GT exporting), and build your own battery. You can build a ~14kWh battery for under $2500, with the inverter, you're...

I still don't understand why you didn't just preheat the DHW (using excess solar) inline before your main DHW heater. This would've been much easier, cheaper, cleaner, used less space in your living area, etc. Not to mention you have less heat loss through a larger single tank than you do...

On my other computer I have a link or two from a large seller with warehouses that stock several brands in NY/NJ, I'll try to remember to share with you when I get back to that computer later. Otherwise, let your fingers do the walking online.

I'm not sure I'm a big fan of what they did converting the lighting from 120VAC to 12VDC, that seems like a waste of money and energy. I personally would likely redo that, especially since killing the 12V battery from your boat in an emergency outage does not sound to me like a good idea if...

Curious what you found out about these batteries, I'm considering ordering some as well.

The most recent EVE specs are posted here. https://diysolarforum.com/threads/the-newest-specification-sheets-of-eve-cells.45234/

The third MPPT is significant, as is the 200A pass through which can greatly ease install and possibly eliminate the need for a critical loads panel.

Has anyone put a clamp on theirs yet to check idle consumption?

For 4 cells or 16? My quote was for 16.

I have not used it yet, although I believe it is possible... but I'd ask SA to confirm the "ONLY" part. I find the main "grid param" setup menu page on the SA inverter(s) that controls grid setup protocols to initially be a little confusing. Maybe it becomes more intuitive after some use and...

If you look at the image you posted, it's not showing connecting the grid connections to the gen terminals, it's showing connecting them to the grid block/terminals which are just to the right of the gen terminals.

Good info, thanks! So what about just going off-grid using an interlock on the main panel? I'm assuming the 120 rule no longer applies and you use the standard max panel rating?

In the US we consider HV max PV input to be 450V-500V Voc, with a couple of very rare exceptions coming in at 600V Voc max. Overseas, I am to understand there are inverters that handle 900V, possibly even higher, and it's not totally uncommon to see these significantly higher voltages...

Did they remove the 5:30am self test shutdown, or at least alow the user to turn it off?

I just saw this after I posted. It would be interesting to see this verified with a clamp meter. If accurate this looks like it's less than half of what the SA 15k is using? If so, that's impressive!

Agreed on the amps, but in some cases that might not account for much depending on your panels and mounting location. My panels would be significantly over paneled with them as well. Although if it worked, I was thinking about mounting some panels vertically on a SSE facing fence (which sees...

I'm sure they will compress and extend with enough force. The question is, how much force is required? I couldn't seemingly get it to do so by hand, although again in the pointless Z axis I could feel some flexibility. Some loadcell data would be useful. If I had access to one for testing, I...

If that's total cost with fees and shipped to your door, that's fantastic! In fact, I'll build another battery or two at that price! If not, then I guess you paid more than $105. :unsure:

I'm sure you can work with a freight forwarder or still find Deye split phase models in other areas (such as the Caribbean), but I personally didn't want to deal with all of this. Not to mention the lack of CS/TS, or even parts availability/repair work in the event I needed it is still a major...

I agree, the concern can be mitigated to a large degree (especially with the SA providing BU power), but the opportunity is still there for someone to disconnect from the grid with the flip of a switch, which I don't like for several reasons... Including the house can be occasionally unattended...

How often is it locking up and requiring a reboot? I think I read it in the thread that disappeared, but have you guys measured to see how much this inverter itself is drawing at idle? I'm assuming you guys are all using the 8k model? Have there been ANY firmware updates or even attempts to...

Only in section 3 (IIRC), where they discuss testing failure modes.

I'm not 100% up to speed on the 120 rule, but doesn't it say you're allowed to exceed the TOTAL load up to 120%? In your case that's up to 240A total. What I don't think I saw was how much is already installed in the panel. If I'm understanding it correctly, if you had a 200A panel, but only...

They certainly seem to be well proven and likely a great option IF the product is available in your market. Sadly that's not the case for the NA market, hopefully this changes at some point in the not too distant future.

Use 6ga back to the existing grounding system? At some point I may add a small sub-panel at the detached dwelling. If so, can I just tap into that same ground conductor back to the main ground?

Sorry to hear this! Please keep us posted with updates. Two failures on this forum alone, given the small number of users, does not sound encouraging. Never mind how many software bugs have been discussed. It will be interesting to see how the others hold up and how the MFG handles the issues...

Another vote for ground mount and mini-split based systems. The GM systems do allow you to select your ideal mounting angles and tilt, which is great if you want to do something like a SE/SW or SSE/SSW panel layout to extend your production across the entire day, which I'd strongly consider...

I'm kind of surprised you unpackaged it, I would've been tempted to put the new inverter up FS after your previous experience!

Excellent general setup overview, Dylan does a fantastic job of clearly explaining things!

I also am very curious what has been addressed with the new firmware! Anyone know?

Okay, so there really was a 10% drop in voltage!

Would anyone mind sharing Amy's email address?

Yes, I'm guessing it sends the gen input directly to loads and/or batteries (depending on settings) in the event of grid outage. Now in the event of inverter failure, I assume the AC coupled micros coming into the gen port become useless, even with the 200A passthrough?

But using the SA software to limit the back-feed gets back to that same concern that was recently mentioned in the microinveeter thread. Some power companies might have an issue with that. (Not that Im agreeing with them, but i get their agruement.)

Wood would not be my first choice given the relatively poor PT used these days. I see how the first option/link obviously anchors, but how does the second (T3) system anchor? Did I miss something on their site, or are they assuming just the wider footprint is enough (sounds sketchy if so)? I...
