I figured someone sold something but I used an old old cell phone with the poweralarm app... Worked great and was plenty LOUD

you need the latest update.
looking at your setting now, and it should charge it when the grid is back.

Hi @Not Aerosmith
I checked the system log on the back end, and everything seemed good, it's working well.
1) Alarm
You still had the internet when there was an outage, coz the inverter took <10ms seamless switch from on-grid mode to off-grid.
Notice is on the screen, and the indicator light will change to yellow, from the software you can see "notice", you can click that you can see "no AC connection". It won't alarm with some loud sound, many users just don't realize that there's an outage, but they could see the notice log if they wanted to check.
2) AC charge
You go to the Web (na.luxpowertek.com) or APP, you can find AC charge, you can choose to enable/disable, and set the start SOC from 0~90%, and stop charging SOC from 10%~100%. I saw you have "start SOC" 10% and "stop SOC" 100% for the AC charge.
That exactly means "grid charging". There's a selection you can make (as picture below) to set AC charge according to time or according to SOC, if you wanted it charge according to the SOC, you need to select "According to SOC/Volt", i saw you set "according to time".
3) the LCD
With the hardware limit, we always have more setting options in the monitoring system (Web/APP), LCD allows people to do the most basic settings.
Other than these, anything else you feel is inconvenient?
Thank you.

Please don't be surprised that @GRV0423 can access the settings. GRV0423 was one of the earliest users who had our North American version 12kW inverters. He has been actively operating and testing various functions in different scenarios. In the forum, he has been voluntarily assisting many LXP users with installation and usage queries. We recognized this value and formally invited him to become an authorized "Luxpert" partner (Luxpower expert). So @GRV0423 has the master account to see the setting when users ask for help and provide their inverter's SN#.
We are also actively seeking more "Luxperts" on this forum, who can contribute their interests and expertise to assist more LXP users. In return for their help, we will show our gratitude by providing certain rewards.
Thx

I had the alarm for almost 2 years and it works great. I wanted it for my GT inverters. Several times I had problems with the breaker and lose the grid to the inverters. If so, the GT inverters shutoff and I am not selling power to the utility. This was a cheap and easy fix. It simply plugs into an outlet that keeps the relay open when there is power. When there is a power failure the relay closes and set off the alarm that is power by a 9 volt battery.
I decided to use it with the hybrid inverters, so I would know if there was a power outage. Today, I found out that without it, I would had not known that there was a power outage. If I don't know that there is power outage, I can't load shed to conserve battery power.

Disagree, I have tried multiple times to set AC Charge start SOC on the LUX software using values between 0-90%. Always return an error code 3. I decided to try setting AC Charge start SOC on the inverters, which is when I learned that there is no setting AC Charge start SOC on the inverter. The LUX software is being asked to change something that is not on the inverter, so it can only provide an error code 3.
I assume the problem was that my inverter LCD display is version 7. GRV0423 has LCD display version 10 and his inverter don't have AC Charge start SOC on his inverter.
You are correct that I have AC Charge stop SOC 100%. However, AC Charge start is not set and the operation fails with error code 3 at any value entered.

One good news is that after the power outage, my batteries were charged by AC. I was at 100% in about an hour., which is what I was hoping would happen.
The power outage lasted over two hours from 15:07 to 17:21. During the power outage my batteries dropped from SOC=98% to SOC=76%. The value of AC Charge start SOC is still a mystery, but we now know that it is somewhere between 75-90%.

There are many snapshots of my inverters on page 75 of this thread and every snapshot shows EPS L1N=0 and EPS L2N=0. Before today, I assume that they were zeros, because StandBy backup Power (EPS) was not being used. Today during the power outage EPS was being used and showed a total wattage, but EPS L1N=0 and EPS L2N=0. Now I am concern, "why is it always zeros?"

as i said before you might need to update your inverter firmware and lcd,

yes it did, you might want to check the spec of your battery, how many battery you have in your system? i think it was charging to high, 14 kw for one battery is a bit to high.
the START SOC is anything below the STOP SOC..

Not one battery, but two batteries each rated at 52V 14.3KW 280AH batteries and the specifications rate each battery maximum continuous charge/discharge at 150A. The LUX inverters have a Lithium GSL setting and the batteries have BMS.
Disagree, My batteries get fully charge at 7AM and over the course of 24 hours may drop as low as SOC=93%. My AC Charge stop SOC=100%. Therefore, your statement the "START SOC is anything below STOP SOC" is not a true statement since SOC=93% is below my stop SOC=100%. My batteries are charge every morning by solar not AC.
The LUX software shows the range of AC Charge start SOC is between 0-90% not anything below STOP SOC. Today during the power outage, I am able to narrow the LUX inverter setting for AC Charge start SOC between 75-90%.

I just had another power outage at 8:39 PM and thank God that the batteries are fully charged.
Power outage only lasted for a few minutes. I did learn tonight that the relay opens and the alarm does goes off by itself, which I didn't know. In the past it was always inside the house and very quick to access and so loud that I ran to turn it off. Now it is outside the house and take longer to reach, so now I know that it will shut itself off when power is restored.
I just discovered that the power outage is not over. Evidently the battery die, my fault I have no idea when it was changed last.
Not sure how my batteries is satisfying the load plus need 1193W from the grid that goes nowhere.
This time the power outage was only 11 minutes. Battery is probably good, but I will change it anyway.

i believe GSL 14.3 kw battery recommend 100A, max at 150A, and peak At 200A, its up to you.
i forgot the max on grid cut off is 90%, i was wrong on that. So i believed that the START SOC is anything below 90% SOC.

My AC Charge Power is set at 12KW on each inverter, which is the inverter rating and only 50A.
The AC Charge Power at 14KW is probably only 7KW per inverter, which is only 30A per inverter or 60A for both inverters The
charge current limit (Adc) at 150A is 48V x 150A = 7200W per battery. It seems that it is working per GSL specifications.
These are my first batteries, so I am really struggling to get everything right. The help and advice is much appreciated.

your inverters were set to charge at 300A, if you do the base math 300Adc*51.2=15.3kw per inverters was pushing about 7.6kw(31.6A ac). I would recommend changing per inverter setting of the Charge Current Limit (Adc) to100A.

Your charge current limit (Adc) to 100A make sense based on the specification charge time, which is 2.5 hours. 100A x 2.5h = 250Ah which is 90% of the battery rated capacity of 280Ah. If I use the specification for maximum continuous charge rate, then 250Ah / 150A = 1.7h too fast per GSL specifications of 2.5 hours.
I have found that when there is a conflict in the specification, best to assume the worse case. Therefore, I will set charge current power to 100A based on 2.5 hours charge time. I agree with your recommendation.

Can someone confirm, that the latest firmware build version is FAAB- 1010? I asked for my firmware to be updated, and this is the latest version I got. LCD version is 0/4 Image version 2 and Icon version 5 which they tell me can't be updated remotely.

FAAB-1010 is the latest build firmware. LCD 10 is the latest for display update.. some inverters can be update remotely but some you have to do it…
By any chance can you DM the the LCD10 update? I asked for it, but so far all i get is crickets. And all this even though my serial number is higher than the one Grace told us for required for remote LCD update. EDIT: Along with instructions for updating, if you don't mind
