I'm interested in the grid interactive features if you ever get a chance to test those
New 10kw NHX AIO From Watts247

Yeah it could be a contender if it can be proven that it works and that the software works. Afaik it's the least expensive grid interactive hybrid inverter out there right now
Oh, come on ... is that all ya got??? Give us the beans on this inverter ... please

I’ll be honest. I didn’t expect it to be this nice. Really just based off the price. It was sorta hard to believe. I’ve had it running my house to see how it handles inductive loads and typical household use. It has worked great. It is an extremely quiet unit.
Hopefully I’ll be finished editing a video on it in the next few days. The wiring compartment is tight. I left a little skin from my finger on one of the circuit boards in there.
mainly because I was trying to put a larger gauge wire then it calls for. But they have push connections for the terminals so it’s workable. I like the display. The settings are grouped in a way that is sensible. It is heavy. I believe 94 pounds. No light flickering or issues running 120v or 240v loads that I’ve seen so far. The monitoring software that comes with it is sorta blah.
but it works with SA. So a lot of people will probably go that route.Single unit, or parallel?I’ll be honest. I didn’t expect it to be this nice. Really just based off the price.

The original Mega was plagued with software bugs, it would be impressive if this unit simply worked without issue. What kind of warranty/support did Ian stipulate?
Did it come with ct? Is it tied to grid? Zero export; will it actually do zero export without the occasional slip-up when a large load starts/stops?
Are the mppt inputs actually separate mppts, or internally paralleled together, i.e. can one pv string have 400v and say input to mppt1 while the other string has 240v connected to mppt2?
I've been interested in these for a while but a bit cautious about being an early adopter.

Ian mentioned he has been working through firmware updates and tweaking things for nearly a year. It came with CT’s. 5 year warranty.
I have zero export enabled. But have not tested whether it back feeds after large loads. I am using the 18kpv as grid, since I’m basically off grid. Each PV string is independent. Some of the peak shaving and separate output settings I likely won’t be testing. I’ll be pushing it more these evening to see how well it does with load balancing.
is it able to zero out the output from the 18kpv?

Could you explain further?
If it has CTs it should have a mode where it sends power back through the grid input to supply home loads.
So, let's say you have a 5kw load that's being powered by the 18kpv: if you have the 18kpv output as the grid input for the megarevo then the megarevo should be able to supply the loads instead of the power coming from the "grid"(18kpv)

An yeah. I had considered that. I’m honestly a little hesitant to try it with the 18kpv’s output.
That’s one thing about reviewing and testing hybrids. They can do so much. Especially this one with a separate output.
do you currently have the 18kpv output as the input for the megarevo?
if so they will sync up. you just need to use a peak shave or self consumption mode and install the cts.
This is why there needs to be adequate documentation or videos on these features. its frustrating to me when the supplier cant provide documentation on if or how a feature works.

I just ordered one of these. Like many I was going to get the 8k Megarevo when it first came out, then saw Will's videos and decided not to. Recently ran across this and emailed back and forth with Ian a number of times. Finally decided to pull the trigger.
My goals were leading me to the Victron for ESS, but it can't change its output when backfeeding for self consumption any faster than 400watts/second which means it overshoots and backfeeds when it shouldn't. Truly not designed to work when you don't have a netmetering agreement.
I'm hoping the NHX is a lot faster than that. I want to run critical loads on the main output, and then zero out loads in my house without back-feeding.
I currently have about 5kw of solar installed, with 20kwh battery and using the 6000xp off-grid inverter (frustrated with the lack of flexibility with this unit, though it is solid and reliable). I am not able to effectively use all the solar I have when it is available, so I'm looking forward to having this unit enable me to use what I have and add another 5-8 kw of solar. I am in Ohio, and our solar is hit or miss. I need to be able to use it or store it when its available because you sure can't depend on it.
Looking forward to seeing others impressions on this, and will share my own once I get it and get it installed.

One thing with Ian is he uses the equipment he sells so it does get some testing done.
I purchased my Growatt for the truck camper from him and the LV6548's. All have worked basically flawlessly for me. I don't always agree with some of his methods for wiring, troubleshooting but when it comes to what he sells, I don't see him selling junk. This inverter does interest me, one of the reasons I've been following along with this thread.
Absolute zero export is what I need from any inverter here if I use grid assist.
Glad to see you are testing one of these.

I can say it is very nice so far in off grid. Which I know you’ve focused on as well. For line line balancing It maxes out around 5.5 kw per leg for 10-15 seconds. And total it seems to be able to sustain 10kw without issue.
I agree with the zero export aspect. I don’t have SA or other monitoring software. So that would be difficult for me to monitor short or long term. I’d like to see some other YouTubers jump in the ring with this also. I think it needs more attention to be honest. A relatively small little box with a lot going for it. (Besides the tight wiring compartment.)

Off Grid handling is not really going to be a proper test.Oh, come on ... is that all ya got??? Give us the beans on this inverter ... please
Most inverters have very few issues when used off grid.
It's when they have to Interact with the Grid that things become problematic.
There are literally Thousands of off grid inverter testing videos out there.
less than 5 videos of grid interactive inverter features.

I do what I can with what I have. 
I did try to zero out the 18kpv but the 2 units did not like playing together. It was like an echo between the two units. A very messy wave form. Lights were strobing.
So unfortunately I can’t speak to that.

Im very seriously looking at a victron setup. I dont need zero export, I export maximally to the grid, but I hadnt seen this 400/w per second spec. that seems very slow. do you have a link?
absolute zero export is not possible. many of the hybrids have a setting to pull wattage from the grid to prevent this. why not get an interconnect agreement with the poco? do they make it difficult?
hey thanks for trying. I appreciate that. do you mind going into a little more detail on how you set this up? ie how the 18kpv and megarevo are connected and what settings you selected in the megarevo?I do what I can with what I have.

I wonder if the megarevo does not have a way to simply power home loads and was trying to push excess to the 18kpv and the 18kpv was raising the frequency to curtail the production. I can see how that could be a big circle J***
thanks for trying though

Yeah - here's a link. https://community.victronenergy.com/questions/158039/multiplus-ii-ess-400w-restriction.html
You can also just search for: victron 400w per second ramp
I really wanted to go with Victron for the quality and longevity. But I don't want to wrestle with the system to get it to do what I want. I want:
- Use all available solar to directly offset loads
- Fill in the gap with Utility
- Choose what level I want the battery participate in offsetting loads
Victron can do that with ESS, but if we are concerned with tripping our electric meters and getting a visit/phone call from the company, then I need better than 400w/s change in feed-in.
Hoping I don't regret my decision. I was impressed with Ian's video, and his answers to my questions.
