New Lux Power LXP-LB-US 12k / GSL-H-12KLV-US with 200A AC Passthrough Current (US Market)

I was told the parallel stacking support is not there yet. Its being worked on and will come as a firmware update. For the foreseeable future I’m thinking the firmware updates will be frequent.

You also need the inverter password to change several of the settings (not all, but some major ones). And, of course, none of this is documented in the manual, but I already had experiences with GSL, so I knew to ask before I attempted to do my install after China hours and on the Chinese weekend when there would be no support. PM me if you need this info.

All is good information.

On Fronius, I don't remember the password, but I believe it was available online. I just searched online for the GSL password or password reset and was unable to find anything.

I did find Huawei password reset, which was a sequence of switching AC and DC switches on and off simultaneously for flashing green leds and flashing red leds, but it never showed actually entering a password or a default password. It did say once reset, you have 10 minutes to enter a password. I didn't get a warm fuzzy feeling that I knew exactly how to do it. Regardless, it wasn't the same inverter anyway, so not important..

Sound like these VIP hybrid inverters were simply for show and tell. It shows and displays all the features, but all the features don't actually work. I guess my worse nightmare is coming true about buying a hybrid inverter.

Maybe a work around solution is to AC couple the existing GT inverters and pass-through the new hybrid inverters, so I don't lose my lower electric bills when there is no power outage. In other words, 99% of the time the hybrid inverters are actually doing nothing.

Second is to buy some batteries and simply use the new hybrid inverter as an UPS and hopefully enough features are working that it can let the GT inverters charge the batteries during a power outage. Maybe this is what Ada,amantium was trying to tell me in his post.

"I was told" always starts to ring bells with me.
There is no source, not any kind of foundation with such a statement.

Please tell me where you got it from, preferably in writing.

I can tell you this about an other inverter: megarevo
When I bought it, it had nothing mentioning paralleling multiple inverters in the datasheet.
After using it for a while, I gave feedback to the oem reseller and of the things I said was "i wish it could be paralleled for more power like eg Sol-Ark"
The response was: "Paralleling is now enabled, if you install the attached firmware"
So yes, firmware does fix a lot of things.
In case of the LuxPower/GSL branded hybrid inverter, it already says it can work with up to 10 inverters in parallel in writing in the spec sheet.
So the fact you tell us "you were told" does not make me believe your statement.

*SIGH*
Just because some one makes a statement "i was told" you believe that persons remark over a spec sheet that says up to 10 unit in parallel possible?
Ask for the proof and then make up your mind.

Got my LuxPower 12klv-US set up this morning. Working as I hoped. I have it grid tied, but not exporting (although I'm not sure I have this part set up correctly). I put a disconnect switch on the utility wiring between the pole and the inverter so that I can easily run offgrid by just disconnecting the pole utility wire, which is my preference most of the time. but, if I have a bunch of house guests, or need to run a load larger than what the PV/batteries/inverter can handle, I can turn on the grid and it will pick up the slack.

I ran only on the grid last night because we didn't finish the install until almost 9pm and were tired and didn't want to figure out the settings to draw power off of the batteries. It passed through the grid power perfectly and powered everything, including my 36k btu central heating system. This morning got up and the panels started powering up about 8:30. It took us a while to get the settings straight and I'm still not sure I have the "no export to grid" right, so I shut off the grid and now I'm running offgrid successfully. The worst part of the install was battling the humongous, 4/0 aluminum utility grid wires. They don't bend easily. The manual still doesn't have adequate explanations of all of the terms they use, but it is much better than the Megarevo manual. Still, there are some things that I believe are Chinese to American translation idiosyncrasies that I still need to get explanations for from GSL on Monday.

I agree with your statements and appreciate your insight.

I joined DIY Solar Forum last month, because I knew nothing about solar energy systems and I wanted to know enough to buy the right hybrid inverter. From what I know, this hybrid inverter seems like my best choice. However, from what I don't now, might make this hybrid inverter a very bad choice. I'm definitely taking a leap of faith and I'm very worry.

breath, i think you made the right choice.
Until proven otherwise, look at/expect the bright side.

Look at the new thread about the Sol-Ark 15kw. It will make you feel better that you made the right decision. Also, you have protections. If by some outside chance paralleling doesn't work, you can go through Alibaba and file a case and get your money back.

I totally agree. Everything in this channel should be substantiated if possible. We can put any gotchas on the front page if it is substantiated. Let's try to keep this thread full of facts and not speculation. The purpose here is to prove out the validity of the inverter and to help others with questions or problems they may be having.

Hrschk said:

Make sure they test the battery communication before they ship it to you, if it isn't too late. they will send you a video of them doing so. They put my inverter under a simulated load and tested it before it shipped.......and send me a video of them doing so. This way you know you won't receive anything DOA. GSL is very good to work with, but you do have to tell them exactly what you want. They don't do it voluntarily. They will also update your firmware remotely if you ask them. But, you must have a VERY stable internet connection to do so. My Starlink connection wasn't stable enough, so I ended up having to do the firmware upgrade on my 8kw GSL inverter myself.

Can you give us some detail about the load tests they did for you in the video? Did they push it. How long did it run?

i don't have any details, I'm sorry. And, in my experience they just do the minimum to make sure everything is working. Not a true load test. But, they have something to simulate a load because they showed me an LED board with a readout of the batteries under a small load. I think it was more to test the battery communication rather than to load test the inverter.

Just pulled the trigger on this today. We’ll
see how that goes! Or not! ;-)

an email snippet from GSL sales rep as I was inquiring about the new product. After some discussion and reassurances I still bought one….

Dear John,

To avoid any misunderstand . I need the clarify as below .

Because it is new released .The inverter does not support parallel function .
And the unit come with white and black version .

Are these GSL words of fact or your wording asking if this is fact? You said that you bought one after assurances. Are these assurances only that it will work after some future firmware update, which is the same assurance that GRV0423 received about the generator?

Are do we know for a fact that these inverters work now in parallel?

Just we are still not seeing the full picture, just 3 lines out of conversation that easily could be taken out of context,
I took the liberty to ask LuxPower directly if the units currently are able to be installed in parallel.
Will followup with the complete response when I get it.

I've been thinking about options if I decided to go with this converter for a while and I'm trying to avoid an independent disconnect...I.e. pulling my panel apart putting in switched etc...I have a ton of room in my existing main panel which is 200 am. Why couldn't I add a 2 Pole Circuit breaker to the panel for the output to the inverter and then have a second breaker at 50 amp because that's Max output of the Inverter going into the panel the CT clamps where they need to be between the meter and the existing panel and the inverter not work As 1A grid supplement comment 2AA backup in case of a power failure during the during the day at least until I can get a battery and 3 still do 0 export??? I'm sure I'm missing something just curious and thinking out loud looking for advice...

Fyi this breaker fits my cabinet style and I have the room...

Can you make a drawing of what you would like to do ?

If you are not on the grid or during a power outage, you are right and the inverter current is limited to 50A.

If you are on-grid, the 50A breaker will limit the 200A pass-through to 50A.
