EG4 NOVA - New Product Line?

[BarracudaBob]

That gets them out of the DIY market where you can't add your own 48V batteries. 100% their design and control.

Something they have been doing with the EG4 Proprietary RJ45 protocole.

From a biz prospective you can't blame them. They are getting beat up pretty bad with inexpensive products flooding the market. Going to cater to the high end professionally installed market. Can't blame a company trying to survive. Soon maybe made in USA stickers on it too.

DIYers do want a screen but commercial installers couldn't care less for them. This product is more for commercial installers.

If that's the case, we don't even need to discuss it in this forum.
But since someone did start a thread about it. They must have not gotten the memo, that it's not for diy'ers.
Signature Solar should make that more clear. (I doubt that they will)

Thanks so much for your feedback, Tim! I'll definitely take this to the team!

Adding to this thread with a newer RE+ video. [Summary text mine.]

The window AC unit is AC, not heat pump. It has MC4 connectors and can connect directly to solar.

The newer, larger battery (16 kWh, 314 Ah) will most likely be on the market in Q1Y26 and will eventually replace the existing 14.3 kWh, 280 Ah. It is about 10% larger, but fits the existing conduit box.

A new, 2-ton, multi-zone mini-split. Can be dual 12K heads or three 9K heads on one compressor. AC/DC hybrid, dual-pole 15A breaker. Can take dedicated solar, grid input, or both.

Finally NOVA. A 100V architecture AIO ESS. Final specs may vary, but 16 kW of AC continuous output. Includes one of the 16 kWh batteries (bottom section). This is designed for solar installers, not DIY. Battery cells from Michigan. Not using Luxpower as a contract manufacturer. Will meet domestic content requirements for the remaining couple of years for the commercial solar credits (Third Party Ownership, TPO, solar leasing). This is a pivot to expand beyond the DIY market. Emphasis on servicing both with different product lines.

Airspool has what looks like the same hybrid window unit for sale now, and the multihead minisplits can also be preordered from Airspool.

So that's interesting, 30-40% credit still applies for installers selling leases in 2026 and beyond while diy gets fucked? Big Solar must have sent a bundle of cash the politicians way for this.

 

[Verbs]

So only if there is a mechanism to ensure consumers can get screwed, then there's government tax incentives? How infuriating.

So do we now need to stand up LLC's to own our equipment and lease it back to us to get the credits?

Yes. The tax credits for homeowners expire 12/31/25. For commercial and lease it is another couple of years, depending on where they are in construction and completion date. Yes, they have more lobbying than DIY does. James Showalter was pushing for continuing DIY as a phaseout just like commercial, but was vastly outspent and ignored in DC. Commercial solar is a big job provider and income tax provider in some States, so their Reps and Senators pushed for a more gradual phaseout.

So, yes. 30% credit still available on leases, 40% when including domestic content bonus for a couple years. DIY never got the domestic content bonus and it needs to be "in service" by end of this year.

You (theoretically) can do that, just make sure you pay/report income tax properly as an LLC. It wouldn't surprise me if they cross-check personal to corporate. And there's going to be issues if your LLC operates as a pass thru on your SSN and not a separate TIN.

A screen doesn't cost much. I don't know why they keep leaving it off.
It's very clear that people want it.

I've heard James @ EG4 say the reason for no screen is because it makes it hard to warranty it for longer because the LCD screen is the weakpoint. Possibly it was certification related?

It doesn't matter for this one, anymore. It's not for the diy market.
It's only being sold to professional installers.

Such bullshit

Such bullshit

Most diy'ers should not be messing with high voltage batteries, anyway.

I'd prefer to make the decision for myself. Signature Solar sells Solis S6 + LG 16H batteries which are ~400V without issue.

 

[Quattrohead]

This to some degree, also harder to pass EMP testing due to the large "hole" in the case.

Not designed for the DIY market, but I don't see why it will not be sold via S2 to DIY'ers.

Because its going to be priced much higher and then be offset by the 40% commercial lease credit. I'm guessing much higher than a Solis s6 plus one or two lg prime 16H bundle they are doing now.

That said, being able to deliver the full 16kW output from one battery is a nice feature, where the 48V solutions require multiples.

It seemed like (in the second video posted) they weren't offering it to anyone except for professional installers.

 

[timselectric]

Only for one hour (maybe). And then the battery is dead.
Still going to need several, if you want to run much during a grid outage.

Adding a little more from other videos (Evan, Country View Solar).

Link to new battery spec sheets (preliminary): https://eg4electronics.com/categories/batteries/eg4-corecell-battery

All the Luxpower stuff is going to be officially certified as EMP Hardened. That's the 6000XP, 12000XP, and FB18, FB21. That's in addition to the 18kPV which already has that cert.

New Chargeverter Plus in an outdoor case. Looks to be basically same specs.

(Gotta love QR codes printed on the front on equipment!)

I have a PowerPro Outdoor & just recieved ANOTHER Indoor just YESTERDAY. Both are supposed to communicate well with the same inverter. (12000XP also arrived yesterday) I planned to add 2 more Indoors over the next 12 months as finances allow.

QUESTION: When the current PowerPros (Outdoor/Indoor) are phased out, will this new one play nicely with my existing ones? Thx

I wish they would offer these ac/dc mini splits with ceiling cassettes. I want to use in a log home and don't want to drill through the logs for those head units. Ceiling cassettes I could run through the soffits and no holes in the log walls.

 

[Plum Crazy Rob]

I wish they would offer these ac/dc mini splits with ceiling cassettes.

Deye (EG4 and Airspool manufacturer) does make those in 18 and 24k BTU and I am pretty sure i watched a Dave@airspool video where he said he could get anything from the Deye lineup. Probably not cheap or fast in general and especially one off...

To others, Sorry. This thread started with NOVA and now going in several different directions (as usual)

They're just slightly increased capacity cells. They're designed to work with the existing inverters, no changes, so should be no issues. Keep in mind, the have the 100 Ah smaller indoor walking as well and that plays nice.

We currently do not have this information available at this time. However, additional details will be provided as we approach the product release.

Why 100V? Everyone else is moving to 400V.

Reason, Propitiatory batteries.
You want to expand the system you have nowhere else to go but EG4.
Most companies use 400V for a reason, which is efficiency at the Inverter and Charging from the PV.
100V makes a lot less sense than 400V when it comes to efficiency gains.
The biggest Benefit is that they could go past 20Kw of output and comfortably use 2/0 Wire from the battery.
