I'm not in favor of doing a ground mount at this location (I agree with other to do it on the south facing roof as it will also help protect your shingles), but if you were to do a ground mount... I would look into running the wires on a pole instead of trying to bury in rock.

Thanks for tagging me, but I actually need 3 MPPT channels and a hair larger inverter, although this looks lot a good opportunity for someone! GLWTS!

Nice work (although above my understanding as well). They didn't happen to mention anything about UL did they?

So sorry to hear the bad news, keep fighting Steve!

This was recently?

FWIW, Renvu no longer sells this product/brand, I guess the link on their site as been archived for a long time.

In theory, being a HF inverter, it should behave the same since there's no internal/external autotransformer.

Well I'm better educated after reading through all this, but still confused as to the best way to handle my own installation, so any suggestions would be appreciated! My DC coupled panels are going on a detached garage, which is about 50' (at the closest points) from the house (where my main...

If you're not looking for split phase, I though the others were still being sold in the US. Is that not the case?

I had to read that twice myself, wondering if I missed something...

As I understand it, I would think all the HF inverters would have some protection built into them to protect the MOSFET's when severally out of balance under heavy load. It's just a matter of where they set the bar. But I could be completely misinformed.

Keith, are you selling your products in the US? I asked on many of your videos, and also inquired on your site, I never once got a response. I took that to be "no" so I went ahead and finally purchased a SA. I'd still like to know the answer though since Deye wont sell here.

Mods, should this all be moved over to the other more main thread so future readers can follow it all? Seems to me that would make sense for the majority of it.

I still think this makes the most sense given her parameters. Well, this and looking to conserve energy by reducing consumption, better insulation, reducing passive solar heating, and likely getting a more efficient AC system(s).

Since I haven't heard back from Luxpower, I went to their site to send a follow-up email. Much to my surprise, the LXP Hybrid inverters from 7.6k-10k seem to have been removed from their website. Only the LXP 12k remains on their site.

Most of the folks I've contacted for batteries since the weekend have been radio silent. Only Amy W. has returned emails, although the pricing I received on Eve batteries was very high. This additional shutdown will not help pricing, that's for sure.

I had calculated mine a while ago. IIRC, I came up with the same numbers they did.

I have some similar racks, any feel for what the shelf and overall rack weight capacity is?

I downloaded and tried the app over the weekend on my Samsung Tab A7 Lite, it worked perfectly. The EVE cells I purchased a couple of months ago showed a build date almost exactly 1 year prior.

Yes. ;) Are you running any of yours in two strings on one MPPT to utilize its capacity? What's your panel layout look like?

During the winter months when the heat is needed the most (especially in more extreme northern locations), most will find you'd need a pretty large PV system to have enough surplus power to do any significant home heating. Short days, low angles, snow, etc all work against PV production and...

Yes, although I'm sure they have design input as they have exclusive distribution rights on some inverters, not to mention (in general) the NA market is most likely to use this much power.

@Josh Gibson have you, or anyone else, considered how to do a flexible or semi-flexible busbar for these two stud terminals for use with inline cells under compression? I had thought about just buying some 2ga. or 4ga. (to handle 200A) flexible OFC silicone wire and making two small loops...

I think time will prove this will likely be a decent inverter (possibly after the bugs are worked out). I thought about going this direction myself, but after watching all the MR issues, I didn't want to be a first adopter, especially with another 100% Chinese company. By the time shipping...

18650, but as packaged from Eve.

My biggest issue when I looked at the micros was nothing was available to support my higher VOC panels. I still don't think any of them will go above 80VOC max, but I could be mistaken. Panel/micro accessability also needs to be considered. Distance was also a factor when a larger system is...

I timed an Enphase IQ7 series microinverter for you today, it was pretty close to 5 min from when it sensed the grid signal to kicking on. Other mfg might be different though.

If you have a cheap way of shipping them to CT, I'd take them, lol!

EVE seems to recommend compression for max longevity, does CATL also? I ask because I've never really looked at their spec sheets or documentation.

The SolArk 5k MIGHT work as it's partly designed, marketed, and sold by a US company, but I believe they are mostly manufactured to their specs by China. So that might be an option.

Glad to hear it! Sadly broken panels happen frequently in shipment, I've had the same exact thing happen.

Sadly they pretty much all come from China, it's just a matter of dealing with them directly, or paying the markup to someone else that delt with them directly. I get where you're coming from though...

I posted in another thread about those kinked "flexible" busbars. I very briefly had my hands on one and I could not get it to noticeably move by hand in the X or Y axis, although it did have some give in the Z axis (which is pretty useless). I question how much give they truly have. I also...

It should be perfectly fine, as long as it's grid tied as excess can be bled off to the grid. If off grid, there's nowhere for the excess energy to go (if the batteries are full), the LUX will not be able to shut down the AC coupling that quickly. You'd need a dump load if off grid and the...

I know it could be done a couple of years ago, but those numbers seem quite low today. I would think you're looking at closer to $2500-$3500 for a complete 48V system using 280ah EVE cells.

I'm guessing nobody on the forum has had one apart to see what's required to replace the fans... I'd think a call to SA might be in order to get the answer.

Great project and lots of good learning info in this thread for others like myself, thanks for sharing and to those folks who contributed with the excellent advice! I have the same panels, they certainly create some more challenging planning with their high voltage!

This was my concern as well. I assumed it did need to be outside and accessible (likely close to the meter), but based on 12kw_2021's intention of mounting his inside, I questioned if this wasn't in fact the case. It didn't sound like his inspector (or utility?) had an issue with it being...

How many amps do you need it to carry?

I have 16 Eve 280ah cells in route. I want a decent active balancing BMS. I will not pull many amps through the BMS, but I will likely get a 200A just to be safe (unless there's a reason not to significantly oversize?) I want to get started on the battery build and have the BMS in route if...

:cry: Any more details or idea why it died? EDIT: Sorry, I just noticed the link.

I am also ready to buy a roughly 8K HF LV split-phase hybrid inverter with CT's now, like yesterday! I've contacted Megarevo and their pricing is certainly reasonable, although the shipping is pretty ridiculous IMO ($580/$650 to CT depending on the carrier). They now have UL cert (through...

I'm glad to see they widened that, the original parameters looked a little restrictive for some applications.

PM sent

Thank you, I will contact him. Also, I have seen some recent images of the Eve 280's with a welded on "adaptor" which appears to have two taped holes, rather than the single. I haven't seen a pre-tapped busbar for it, but it does look like it might offer a superior connection. I'm curious to...

Agreed, I just get a little nervous about those plastic sleaves/inserts that lock the shelfs in place and most seem to use that same basic design.

I'm dumbfounded they've handled this inverter introduction to the market so poorly. Not only has there been no sense of urgency for getting the software ironed out and all the features unlocked, but no communication either??? Crazy, I'm sure I'm not the only sale they've lost over it...

Thinking about this more, I do have some thinner copper in roll form laying around that would be flexible enough if a hump was left in it.

Thank you for the verification! Has anyone else done a similar test to compare?

Thanks Devin for your honest answer! So I'm assuming using the 15k OG would be wise if this were a real concern? Likewise, using it GT with only a 100A service would drastically reduce the wear, correct? On a related note, is the same true for the fans on the 15k, or can those be...
