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

[fromport]

Update in my case:
despite the firmware update, it still gives me the Riso error from Solar.
As explained in earlier post, I already exchanged Sharp 208 watt panels for Kyocera 158 yesterday.
Still same issue.
This morning hooked up an Solis-3.6-2G-US inverter which I had lying around.
It is my experience these units are really sensitive.
But the Solis works without problems, where as my LP gives me the isolation error.
I now have to wait till the technicians in China wake up and hopefully I still have some daylight to let them remotely debug my unit.
Keep you posted.

Turns out they were still awake.
Don't know yet what they did, but it suddenly started producing

This product certainly isn't without issues yet, but I am really impressed (as stated by other people) about the support.

The inverter screen is not showing the right value compare to app value…

The Charge Energy is showing the Battery Discharging.
The Export value is showing the Import value…

The inverter screen


The APP…

I just checked mine after i saw your post from FAAA-0B0A-> FAAA-0D0A

How is your GSL-12K working? It seems that you installed the GSL-12K very quickly and was using it for energy storage system with peak shaving function. I assume that means that you had the GSL-12K working with your solar panels, batteries, BMS and scheduled exporting for peak shaving? The only function that I remembered you reporting not working was the generator function and it was to be fixed with a firmware update within a week. Can you give us an update, if everything is still working and that you are still loving it?

Interesting, I was writing the post while you were posting some of the information. There are still some questions not answered from your simultaneous post.

Inverter is working fine with no hiccups the only thing is the inverter screen showing the wrong value compare to the app… The first 2 days after installed i did couple experiments with the setting how the inverter behave but when i figure it out everything work flawlessly… the Gen port is working properly but i asked GSL if they can make an option the Gen port for ac couple input… firmware were sent me once but im i still waiting on the newer update…

Any recommendations for 15KW of batteries that works with the GSL-12K inverters? I don't know what BMS is in the inverter, but GSL was recommending their batteries using CANBUS. I don't think that I want to wait 2 months or more for batteries from GSL. I prefer to buy something in-stock in the USA.

Can be use any type of battery but use lead acid type and battery volt instead of %…

GSL inverter use pylon protocol with the battery pack…

After most of a day my LP working as a grid tied only inverter I am impressed.

With my other hybrid inverter (megarevo) everytime I power it down to do something , it starts statistics for there on from 0.
So if I power it down 3 times, i need to add 3 values to get the daily production as an example.
This unit with monitoring just continues and it keeps adding to the daily kWh generated.
I really appreciate this behavior over the other hybrid inverter monitoring.




This is from 15 x 158 watt panels hooked up to it.
Top power I saw was 1609 watt PV with 1521 watt to the grid
That would be 94.5% efficient

But I have my doubts about the readings.In the above graphs more power was fed into the grid than was generated by PV panels.

Later in the afternoon, I disconnected the AC to the grid and measured the DC power to keep the inverter running, without loads.
It turns out it was 0.1 amp @ 438 Volt or about 45 watt, which isn't too bad imo.

I have to hear from anyone what was wrong/what they altered in order to make my inverter function like intended.

BMS == Battery Managment System.
That is always in/with the battery, not in an inverter.
The inverter talks to the BMS in order to know amps/volt/SoC (State of Charge) and much more.
Batteries & inverter need to speak the same language (protocol) and the same interface (RS485/CANBUS).

CANBUS https://wikiless.org/wiki/CAN_bus?lang=en
RS-485 https://wikiless.org/wiki/RS-485?lang=en

Just make sure your batteries & inverter have the same hardware interface (both RS-485 & CANBUS use RJ45 connectors but the signals are really different) and the same protocol although I think pylontech seems kind of being the standard at the moment.

The solar field has a bit of a wild west feel to it, that definitely reminds me of IT back in the 80's and early 90's. Demand for turn key commodity level products in a technically complicated field full of quickly thrown together solutions at both the hardware and software levels. A lack of maturity in the industry was everywhere outside of the big iron, and even they stumbled.

I'm seeing it now in solar, slowly moving from a niche to mainstream commodity. It doesn't seem to matter the manufacturer, they're all having their growing pains. I don't want to sound like I'm defending GSL/Lux/Linio because I don't know any of them, but I can say that I'm impressed with the repeated reports of service quality from GSL. That's the kind of thing that would get me to buy products from them, despite early bugs being reported. It's also the kind of thing that would set them apart. How many times have you heard of bad customer support, or terrible customer support? Consistent good support would be very refreshing.

I don't mind a few bugs here and there. But one that concerned me the most is overcharging of the batteries.
The company acknowledged that voltage is off by 0.6v. and the inverter can't stop at a set stop charging voltage or set time interval.
Here is the last photo after the batteries were disconnected. The inverter shows it was still charging the battery at 55.1v (+0.6v) when the stop charge voltage was set at 53.3v

I really like the features and the price of this inverter. But I don't want to burn my house down. My wife will be really upset.

What is your absorb set voltage and float?

 

[OutlawSolar]

What is your absorb set voltage and float?

both set at 53.3v

 

[Luxpower_Gilbert]

both set at 53.3v

Try your absorb setting higher than your float… try 54v absorb and 53.3 float…

How come your setting is low? What battery are you using?

 

[OutlawSolar]

for testing and safety purpose, I set both voltages artificially low so I have more time to shut off the breaker if an inverter doesn't do as it supposes too.

Try do it when your around home…
mine doing a good job keeping at 57.8v for absorb and 56v float for 4 hours.. it seem high because I'm trying to cycle the battery at the moment…

 

[OutlawSolar]

I already took it down and put it back in the box to ready to send it back.
Having spent early years as a test engineer, I feel that this feature rich charge and discharge logic needs to be thoroughly tested and verified. There are just many combinations of settings of times, voltages, power levels in many selection places that the interaction between them can be complex.

Bottom line, this inverter needs to be thoroughly tested before selling to the public. For a US based company selling it, this will also presents a big product liability issue.

I was very surprised/shocked when received a blank inverter with no brand on it ( that was drastically looked different from the pictures shown on LinioTech website).

This inverter has many promising features, I like to see it be brought to a completion.
For now, I will wait out.

Totally agree!

When I find a battery and search for compatible inverters, it never list Lux Power. I have seen some batteries list Solar Assistance, but then this software doesn't list Lux Power inverters nor Pytes batteries.
I searched Lux Power for compatible batteries and found this list, but not much luck finding local suppliers for these batteries:

 

[Not Aerosmith]

Luxpower compatible battery available locally is the new EG4-LL V2:

RS485: P01-EG4 EG4, P02-GRW Growatt, P03-LUX Luxpower, P04-SCH Schneider
CAN: P01-GRW Growatt, P02-SLK Sol-Ark, P03-DY Deye, P04-MGR Megarevo, P05-VCT Victron, P06-LUX Luxpower

I scanned the other EG4 batteries manual and I didn't find the same protocol settings for them. EG4 is planning on a firmware update for the version 1 batteries. You need to do your own due diligence for the other EG4 batteries to determine, if they are compatible or will be compatible with the Luxpower inverters.
