New 10kw NHX AIO From Watts247

The grid connection is bi. It can push to or pull from the grid. Could check for correct ct orientation with a clamp meter.

I though if the inverter was inverting, load1 is hot? Is the rsd active?

Mine power up on battery w/o grid, or pv.

I would ask how hard is it to get the jk talking to the inverter, but I've read enough bad stuff about the pb boards to stay in open loop.

Thanks for the feedback. The manual wasn't clear on the Grid contacts being able to push and pull current. That is what I was hoping for.

I double checked the arrows pointing to the meter, but I can always switch and see what it says.

Load 1 isn't hot, but I had the backup box unchecked. If the grid lines back feed then I wont need to use the load 1

I tried a few different setting tell I found one that worked. It seems to work great now. But I need to tweak the parameters in the BMS.

Mine powers up with battery, but not with AC. I wasn't sure if it required DC to turn on or if its a setting
 
I would confirm with a clamp meter which direction the current is flowing. It's possible the direction indicator on the ct is wrong.

Load2 can be set to switch on/off under certain parameters but load1 is default on, or it is on both on mine. Did checking the 'backup' box turn load1 one?

Although I have not tried it, add copy states this inverter can be used w/o battery and is grid interactive. One would think that it 'should' power up w/grid. 🤷‍♂️

Sounds about right. Wait for a while to research the product and get some feedback. Finally purchase the product and bam, out comes the latest and greatest. Urg.

Korn,

I am considering the NHX-10k, NHX-12k and the new Growatt SPH-10000TL-H-US 10k. I asked Ian if he was doing a video on the new 12k (no response yet) so we can get a good look at it and some valuable feedback seeing it in action. It looks to be very similar to the EG4 18kpv, but not sure how much, if any, of the DNA is shared. I am sure Ian will do a video series similar to his vids on the NHX 10k.

I am waiting to see if there are any Black Friday deals to be had... I plan on making a choice by then. Pricing and user feedback on these units are key to me.

My understanding is it basically the EG4 18kpv. It also supports AC coupling and such.

In an email Ian confirmed that the NHX does not share any DNA with the Lux variants. He said it was completely different. The specs look pretty close but the inside wiring area looks significantly different than all the Lux 18kpv models, which is why I asked.

He is working on a launch video which from the sound of it should be out soon to introduce the NHX 12k unit. :)
 
The NHX series is made by Megarevo as far as I’m aware.

The 12k will have some similar stats as the 18kpv. But yeah it’s a completely different inverter.

Do the nhx have a way to set or limit incoming grid power in kw?
Click to expand...

I know it has settings to limit battery power as a percentage of it's output limit. You can also set the max charge current.

Not sure if that answers your question.

Thanks for trying but I'm looking for something else.

Let's say shore power is only 20a, can the nhx be set to only use 20a for loads and charging?

I looked through the manual and couldn't find this. It has a way to set generator power.

Charging yes. Restricting the maximum load? Maybe. Solar assistant has the option to set grid power to less than 100%. So if this inverter has a maximum output of 10k I think if you set grid power to 20% that might do something like what you want.

Ok interesting. So maybe via solar assistant but not via the inverter's actual screen?

Everything SA does should be possible through the inverters interface but sometimes SA calls the setting something different than what's in the inverters gui.
 
While I can wire a thing or two up, I'm totally not a computer guy. If I simply need for the nhx to start charging the batteries from grid at a certain voltage and at a certain rate, and stop charging the batteries when they reach a certain voltage ... what settings are used? The battery bank is @52.5v and one more day of clouds and rain before we get any sun.
 
So I hooked up my 10KW inverter "Grid" line to the "Gen" (on breaker) port of the Enphase System controller 2. Enphase thought my CT's were backwards because it showed Power moving the wrong direction. When I shut off the inverter the power movement stopped. I am unsure if it was sending power to the grid or charging my Enphase batteries. But it was pulling power from new battery. I just got my Solar Assistant unit but need some cables and more USB's. So still a lot to figure out.
I might hook up "load 1" to back feed my main panel. Just trying different options at this point.
 
I got my NHX-10k up and running. I got solar assistant installed and working. I was hoping it would allow the ability to adjust the configuration, but it seems to just monitor it. I was hoping to use it in a way to adjust things realtime with other home assistant CT’s. :( has anyone been able to create some automation between the NHX system and solar assistant/home assistant and Enphase? I was hoping I could create some software logic to help adjust the battery charge and discharge. If anyone has thoughts let me know.

This?

I have installed Solar Assistant and Home Assistant. I have both working and talking to each other. Home Assistant see's both systems. Enphase and NHX-10K. Now I need to figure out how to best configure both to save and store as much solar produced power as possible. If anyone knows of anyone who has done some automations in HA for 2 different systems lmk. Here are my Month-to-date stats.
82 kWh Power imported
154.8kWh Produced
125.6kWh Consumed
106.6kWh Exported
from my 6.6k Enphase batteries
19kWh discharged
25.2kWh Charged
My goal is to have the NHX charge and discharge based on solar production from the Enphase. And discharge when solar isn't producing. To reduce exporting and grid power.
I have the NHX "Grid" connected to the Generator breaker in the Enphase System 2. I then have "Loads" connected to the main sub panel as a back feed. Any recommendations on how to proceed using what I have would be appreciated and welcomed. My new battery is a DYI 16s w/314ah box. I have a second on order that will double this.

Do you have your cts connected at the main panel?

Yes I have them connected to the feeders coming into the panel. The numbers seam to be different then what Enphase shows, but I do have them connected.
For now the best way to get the battery to charge. I have to put the inverter into Battery Priority mode. Then self consume to discharge. I tried the time of use( Peak) but was unsuccessful having it charge and discharge as expected. But its likely me just learning the setting.
My thought was to get additional CT's that work with Home Asst if needed and see if I can get the inverter to adjust based on extra power being sent to the grid.
I finally did a diagram of my system. lol Don't laugh it was my first attempt with this program lol

Right now to get it to charge and discharge. I change the status of the inverter between "battery priority" and "Self consumption". It sucks doing it this way. I am still trying to figure out Home Assistant integration. I can see both systems but unsure how to create an automation between the 2. The numbers don't seem to match the Enphase diagram/usage CT's. Production works but not the net production and amount exported. I might need to figure out how to write some code (ugh not my forte).
With my diagram above I might change the wiring of the inverter. Since the "Grid" is bi-directional. I might remove the loads and just wire the "Grid" to the panel. When I back feed to the Enphase panel it messes up Enphase's power flow and CT's. It sometimes will also charger the 3T batteries. I don't have anyway of seeing if it's back feeding to the grid.
I am tempted in getting one of those home CT kits that show where the power is being used and going. It would need to be compatible with home assistant.
