Seconded@Will Prowse PLEASE review these.
Is this grid forming inverter? Can I create a micro grid and connect my existing grid tie system to the generator port as many other inverters suggest?Good Morning.
this is in fact the same model that can be paralleled to 8 units, we have made extensive firmware updates and features to the vanilla model you see online.
We have been running these Indoors, outdoors, as EV chargers, Welding and Plasma Cutting Operations, Compressors, Motors, Heat Guns, Forklift Charging stations etc etc. more videos to come soon.
It has a ton of features, like any newish product, it still has some small bugs / deficits. Asking the Western Mind to communicate with the Eastern Mind is always a challenge, as there are many philosophical challenges in the way we view the world, nevermind technical concepts.
I personally have been working with the many Eastern software/hardware engineers now for about 30 yrs, and it remains a challenge to get a point/concept across.
These have a 5 yr warranty,
we are also stocking some spare parts, even though we have never managed to kill one yet.
Paralleling is easy, just as simple CAT5 cable between units.
Solar Assistant Does work with these units, we have to make a special plug for now. (basically a 4 pin molex plug (same as fan connector )) this plugs into the mainboard
We have these mounted in the Rain and Snow.
The most common failure on any electronics is having ambient air run through the PCB (Dust , Humidity, etc is a sure killer - see what Florida does to a circuit board) This is why we are moving towards IP65 + units in future. all cooling is done externally.
I shake my head at some local suppliers offering warranties longer than MNFR warranty, especially where they suck all this soot/moisture and dust through the PCB.
At the most recent trade show, one of the recently well known manufacturers (who has only been on the US market since April 2023) admitted that they cannot get their open air models to last past 2 yrs near the ocean, but yet they offer a 5 yr warranty. Boggles the mind.
On the NHX series, will be doing videos shortly on idle consumption, ( its higher than 15w for sure), as well as load tests etc.
Things can get quite complicated or as simple as you want with grid interactions. Some things, I still scratch my head.
Like Sol-Ark, it can take a few weeks to start to understand what its going to do when I change setting X.
That's why the manual we have updated on our website has common USE case settings for the most common cases.
Arriving late Jan 2024. Add yourself to the waitlist

Pending all the recent snow storms, these should be here at our warehouse early next week.
Tks for reading

I was just watching this again and it looks like all the load testing that was done up till the 12 minute mark had the grid in parallel and so the grid would have supported any surgesIan has a video up on the NHX inverter. I need that solar awning as well.
What is the difference between this:Looks like sungold power has a version out too
It's grid interactive meaning you can sell to the grid, peak shave, and in theory zero out your grid usage with the included CTs.What is the difference between this:
10KW 48V Split Phase Solar Inverter
Highlight: ★ All in one unit: 10KW Pure Sine Wave Solar Inverter Combined with Max 200A battery charging, 2 MPPT Solar controller inbuilt, Max.Voltage of Open Circuit : 500VDC, Split phase (120V/240V) or Single phase (120v) output. Wifi module is included, which allows the user to view the...sungoldpower.com
and this:
10KW Hybrid Inverter 48V Split Phase
Highlight: ★ Hybrid Split Phase Inverter: 10KW Pure sine Wave Inverter 48V DC to AC 120V/240V, built in 4 MPPT Max 500VDC input each total Max 15000W PV input. ★ Multiple Charging Modes: Off Grid Solar Inverter have 4 charging modes: Only Solar, Mains First, Solar First and Mains & Solar hybrid...sungoldpower.com
Both are 10 KW, hybrid, 48V split phase.
One costs $1670, the other $2400. What do you get for the $730 extra?

Sorry if these are noob questions...It's grid interactive meaning you can sell to the grid, peak shave, and in theory zero out your grid usage with the included CTs.
It says can also sell from battery to grid, for those areas that pay well for such a feature
True grid interactivity is a big deal
Ok so your battery is just for backup purposes? It looks like the cheaper inverter, if you set output source priority to uti it will use solar and grid together so when solar goes down you power your loads from the grid.:
If solar, use it to power loads first, anything left over charge the battery, anything left over push into the grid. Any deficit in power, pull from the grid. If grid fails, use solar and battery to power the critical panel loads.
This one looks very very similar to the EG4 8k that was discontinued...Looks like sungold power has a version out too

Made by the same company. This one (and the watts247 one) has a touch screen though, and is cheaperThis one looks very very similar to the EG4 8k that was discontinued...
Btw sigsolar still has that one.This one looks very very similar to the EG4 8k that was discontinued...
There we go, the key bit, without CTs (and the associated controls), you can't use the battery to do zero export and use your battery for local loads only.It has no CTs so it does not have the option to use the battery to support your main panel loads.

I'm not sure if this one supports ac coupling. I also don't know if it's smart enough to charge the battery based on parallel ac sources exporting to the grid.If you compare this:

To an EG4 18KPV unit, what are the functional differences? Obviously there are differences in power ratings and one might claim a quality/support difference, but functionally, what capabilities does the EG4 18KPV have that this unit lacks?
If I have a 10 KW critical panel load, this $2400 unit seems like it might be mostly equivalent to the 18KPV for about half the price, no?

I'm interested in DC coupling and this has 4 MPPT versus 3 for the 18KPV.I'm not sure if this one supports ac coupling.
The manual shows a parallel connection diagram and setup, section 9.I also don't know if it's smart enough to charge the battery based on parallel ac sources exporting to the grid.

Are you talking about the touch screen one? It seems to my that the srne based one can do everything you need, and save you some money, no?The manual shows a parallel connection diagram and setup, section 9.
They also show a 3 phase triple up diagram.
I notice in the parallel diagrams that the grid side neutral and the load side neutral are not connected together. I wonder if this is a requirement to use these boxes, or just an oversight in the drawing.
The manual and spec sheet doesn't say UL 1741, but the website does, so one wonders if that is true or not.
One critical parameter (for my use anyway) is the transfer time to battery on grid failure, that is not listed.
I'd need someone to try using this device and test it in various ways before buying one.

Everyone is scared after the first megarevo debacleLooks Interesting.
Can't wait to hear some feedback from the first couple of buyers.
The $2200 price is unbelievable.
