Huge premium to get all the various approvals if your local area requires it. I don't believe the 6000xp has been unit tested together with the eg4 280Ah battery, just has UL 1741 certification.

I question that.I went on the UL site and most of those certifications don't mean anything. There is also no documentation anywhere on the EP Cube site and EP Cube is not UL listed in any way.TUV Rheinland is a listed NRTL but at least there are ETL certification letters for the EG4 equipment.In my opinion this is just an overpriced shiny object like the Tesla and most others of this type.They are targeted at people with more money than brains IMHO. Give me a good argument otherwise.

Collecting the leftovers of the Great Sky Reactor.
You can install a 400 amp transfer switch and feed both panels from a single source.
That’s what I did.
I’m Not using EP cube but Sol-Ark for mine but will work for EP cube.
Canadian Solar told me not possible.

The inverter doesn’t know if it’s powering 1 panel or 40.
They might not want to support that configuration but it will work.
They said the inverter maxed out at 200A.

The only reason that it wouldn't work. Is if the inverter isn't large enough to handle the loads.
But, it can still be connected this way.

You are not pulling anywhere near 200 amps.
That’s just the what the panel is rated for.
400 amps doesn’t mean your pulling 400 amps.
I have a 400 amp service and my max pull has been 80 amps.

C'mon guys.....WHY?

How well it works as UL1741SA input into Sol-Ark 15k or EG4 18kpv. AC Connected PV into Smart Load connection.
Can the SA (or EG4) and the EP be connected to the same battery in that configuration (assuming you set the appropriate charge rates so you don't overload the battery).
Can you hook up any 48v battery, or only theirs? Does it need a battery, or can it work as PV inverter only?
How well does the MPPT handle shading, etc.

The cube has a less wire factor. Many people are afraid of wire from the installation side. Maybe better documentation.
I'm not sure why you are concerned about it. Just examine each and decide.

WOW...8 grand for wiring
What EG4 setup are you comparing?C'mon guys.....WHY?
It looks like the base ep cube 9.9kWh system with a 7.6kW inverter is $9806 from signature Solar. But it has all the certifications needed to get permitted and be legit.
The EG4 power pro system with the 18kpv and 14.3kWh is a comparable price at $9096. You get the certifications and better capacity and inverter output but what system are you comparing that costs only $5k and has all the same certifications so it could be grid tied and all that?

I think he tried one once, didn't have any problems, so he couldn't make money off views doing more videos.
But he does recommend it for UL listed grid-tie system. I think it was the only one he felt he could recommend at the time, maybe a couple others now.
Yes, here is his recommendation and affiliate links.

In addition to SolArk, he has now added EG4 18kpv with PowerPro battery.

A PowerPro 14.3 Kw and a 6000XP. Pricing for both was right off the Sig Solar site.
Isn't the 6000XP an off grid inverter without any UL9540 certification and can only be used in off grid/non-permitted installations?
It's not a bad unit from what I've seen but it doesn't quite match up with the EP Cube in terms of being able to be installed legally as an ESS in a residential setting AFAIK.
Not everyone cares about that but they're not quite 1:1.

I never said they were 1 to 1. The PowerPro actually has more storage.I should have clarified that my point is from a battery perspective.Still think the EP Cube is grossly overpriced as is the Tesla and most others of this ilk.Look at the stickers I posted before.Inverter certification is UL1741 not UL9540.Both batteries are 9540A certified which is the UL test method.The 6000XP will not export to the grid, but it does pretty much everything else very well without the need for gimmicky, expensive "gateway".
Don't get me wrong, I've love to have the fully certified ESS(UL9540) system for as cheap as some of these off grid systems.
The PowerPro definitely seems to meet the criteria for indoor usage in Canada, USA, and probably elsewhere.
I think the inverter has to be certified WITH the battery as an entire ESS system in order to get the UL9540 required, which is where the mix and match I think doesn't work if you want to have the entire thing inspected and stamped as approved by your local inspector(probably varies somewhat by location).
I'd guess 90+% of the people on this site don't care about having their system inspected and approved, but the EP Cube seems to be designed for those that do, and also those that may want to sell back to the grid.

The eg4 12k and the power pro battery have been tested together as a unit, for UL9540 certification.

As is the ep cube system. Some states/areas that's now required.
The xp6000+power pro battery has not been tested together. The power pro alone has UL9540A. No UL9540 in combo with the xp6000. No grid interactivity.
Seems like you are comparing apples and oranges.
