Eddie told me that if I click on the values under Solar Yield, Battery Charge and Feed-in Energy that I get additional information. Grid will toggle between import and export, Battery will toggle between Discharge and Charge, and Solar Yield provides additional information.

I had no idea that the software included this feature.

I really like the Luxpower software.

‘Operation failed, error code: 3 means that some inverter changes can only be made when the inverter is in standby mode. For me it was very frustrating not knowing why I was getting error code 3 when I tried to change some settings, so I did an internet search for the answer. Luxpower has published online the answers to 6 FAQ. I have shared the document for others struggling with some inverter settings or definitions.

Standby Mode will not fix error code 3 on changing On-Grid Cut-Off SOC above 90%.

I was trying to change on-grid cut off, because my system was charging to 100% with solar and then when consumption > production, it would discharge to 90%. I wanted my batteries to always be 100% as an UPS for power outages.

I discovered that the fix is charge first set SOC to 100%.

Now when consumption > production, my batteries are no longer discharging to 90%.

It appears that the Luxpower software can do whatever you want. However, for a lay-person like me it is sometime difficult to figure out, but so far not impossible. If impossible, there is always support.

are you going to use your battery for back up only?
charge first (pv) setting is use when you don't want to discharge you battery.
but if you only want to battery to use as a backup only then set On Grid Cut Off SOC(%) to 100%

 

[Not Aerosmith]

but if you only want to battery to use as a backup only then set On Grid Cut Off SOC(%) to 100%

How??? Your post makes sense, but I have tried repeatedly to set On-Grid Cut Off SOC to 100% or even 95%. I have tried setting it with inverter on "STANDBY MODE", so far I have been unable to set On-Grid Cut Off SOC >90%. The solar will charge the batteries to SOC=100% or close, but when consumption > production, the batteries will discharge to 90% when on-grid. Luxpower only provides an error code 3 for on-grid SOC > 90%. If you think that you have managed to set it at 100%, then hit "READ" and it is will change SOC to 90%.

I really hope that I am wrong and made some stupid lay-person mistake. Maybe error code 3 means that the inverters need to be in standby mode plus the change must be made on the inverter LCD screen not using remote software settings. I have spent hours trying to get the inverters setup the way that I want.

My understanding is that "charge first" use solar energy first to charge batteries till fully charge with the grid providing the power for consumption. Afterward the batteries are fully charge, the solar energy is then used for consumption and/or export to grid. What important is that with "charge first" that it didn't discharge the batteries to SOC=90% when the consumption > production. Normally, when there is no power outage, the batteries should have only discharge overnight to about 97%, so in the morning batteries will be SOC=100% in < hour.

However, I will admit that "my understanding" is limited. I need help.

as of now it can be set 0-90%, lux been updating the web and app recently. i think it would be better if you cycle your battery from 100% to 80-90%, its better for the battery than to always stay at 100%.. if you still want to kept it at 100% use charge first and set it to 100% and use the timer with 5 mins gap.
Charge First Start Time 1: 08:00
Charge First End Time 1: 07:55
or try set
Start Discharge P_import(W) higher than your regular load kw.

Just read your email and checked my settings at 9:30PM. Unless we have a very bright full moon or the street light next to my house is very bright, my system may not be working properly:

I do have 28.6 KW of solar panels, but still not expecting them to work at night even at 1.58% or 452 w. Another mystery that I need to solve.

My solar panels usually start producing about 6:15AM and by 7:55AM on a good day may be enough to power the house. Trying to follow your advice, I would think in my case that possibly to discharge the system to 90% that:
Charge First Start Time 1: 06:00
Charge First End Time 1: 05:30
My family normally exercise during this 30 minutes, so I will be able to check the system status to see the depth of discharge.. Any schedule outages for maintenance are normally schedule between 9AM to 4PM. Our bad weather or heavy rains normally occur in the afternoon and sometimes can cause a power outage. I should have full power for UPS when I am most likely to need it. Usually any outages at other times are normally brief or < hour.

I appreciate your help and advice.

At least one mystery is solved. The software was left running from earlier and the moving arrows were still moving, so I assumed it was working. I just needed to login and the system is performing as expected:

 

[Not Aerosmith]

I was curious how much the batteries would discharge naturally by themselves. This morning I checked the system at 6AM and the batteries had discharged overnight from SOC=100% to SOC=93%.

I manually turned off "charge first" and at 6:15AM, the system was using solar and batteries for consumption with the grid:

At 6:35AM the batteries were SOC=90% and shutoff with a;; power from solar and grid. In 20 minutes the batteries had discharge from SOC=93% to SOC=90%. The batteries should now stay off until the solar production > consumption with "charge first" off.

At 7AM the solar production > consumption and just started charging the batteries:

At 7:15AM I enable "charge first" now the solar is charging the batteries with consumption from the grid. I went ahead and set charge first to start at 6AM and stop at 5:30AM.

The batteries were SOC=100% at 8:05AM. Today I did it manually to have a better understanding how the system would respond with and without "charge first". Everything work as predicted by GRV0423.

Tomorrow everything should happen automatically, since the inverters are programmed for "charge first" to turn off at 5:30AM and turn on at 6AM. I really appreciate the help. I should have batteries at fully charge for UPS when I am most likely to have an extended power outage.

I believe with GRV0423 help that the Luxpower software is now properly controlling the system as I wanted. Thank you.

AC Charge is disable, which means that batteries can only charge when there is solar.

I wanted to setup AC Charge, but unable to set a lower limit. I get an error code 3 when I set Start AC Charge SOC=90% or SOC=50% and even the default value SOC=0%. I put the inverter in Standby mode, set Battery Charge Control to SOC, and set AC charge according to SOC/volts. I tried doing it with AC Charge enable and disable.

All the setting of AC Charge seems to work except Start AC Charge SOC and AC charge according to SOC/volts. AC Charge gives you an error 3 code regardless of the value enter. AC charge according to SOC/volts indicates successful, but do another read and it reverts back to the default according to time.

Has anyone been able to get AC Charge to work???

tell me what setting you want to use, how you want to use it and i will help you

I want to set Start AC Charge SOC=80% and Stop AC Charge SOC=100%.

If the solar panels were unable to charge the batteries, I would need the grid to charge the batteries.

 

[Luxpower_Gilbert]

I want to set Start AC Charge SOC=80% and Stop AC Charge SOC=100%.

You set it like that then set the time you want to ac charge the battery.. I assumed your using charge first pv timers to prevent the battery discharging…

 

[Not Aerosmith]

To set time I need to use Set AC Charge "according to time", because "according to SOC/volts" grays out time and not let me enter a time. I am still unable to set any value for "Start AC SOC" without an error 3 even with time set. The time was set to avoid any conflict between Charge First and AC Charge. It really seems to me that Start AC Charge SOC=80% and Stop AC Charge=100% should work.

I remembered that on-grid cutoff demanded SOC=90% or less, so I tried setting Stop AC Charge SOC=90%. I still was unable to set Start AC Charge SOC=80% without an error 3 code. No idea why this feature is not working for me.

 

[Luxpower_Gilbert]

try set it in the inverter not from the web. make sure you put all zero if your not using the timer..

 

[Not Aerosmith]

Luxpower default values are on-grid cutoff for batteries SOC=90% with batteries only >90% when production > consumption. When consumption > production then batteries discharge to SOC=90%. Luxpower default is consumption-batteries-grid.

Charge first let me charge the batteries more quickly to SOC=100% when solar production is available versus waiting for production > consumption. Charge first doesn't discharge batteries to SOC=90% when consumption > production when using on-grid power. Charge first is batteries-consumption-grid.
I
AC Charge should let me set start charge batteries SOC=90% and stop charge batteries SOC=100%. Two software settings don't seem to work, which are AC Charge start SOC and AC Charge according to SOC/volts. According to the inverter LCD display AC Charge is enable and set for SOC with stop SOC=100%. The Luxpower 12K hybrid inverters don't show an AC Charge start SOC or AC charge according to time or SOC/volts.

Mystery maybe partly solved. I don't see either of these software settings that don't work on the inverters LCD display, which may be the reason for error code 3 and why I am unable to set them successfully. It may mean that I need to upgrade from LCD display version 7 to 8 in order to see start AC Charge SOC and AC Charge according to time or SOC/volts. The software show the acceptable AC Charge start range as 0 to 90%.

If anyone has the LCD display version 8 can you please tell me, if there is a start AC Charge SOC. I may need to upgrade from version 7 to version 8 or the latest LCD display version. According to GRV0423 the AC Charge start setting is not on the Luxpower inverter LCD display and he is using version 10. Obviously Luxpower software is unable to change a setting on the inverter that is not there and must return code error 3. Mystery solved.

If AC Charge is disable, I believe the batteries when nearly depleted from a power outage will not be charged by AC when the grid is activated, but instead need to wait to be charged by solar production or a generator. The Luxpower software can set AC Charge stop SOC=100% and set AC Charge using SOC values. We know that the Luxpower range for start AC Charge SOC is between 0 and 90%, but we don't know yet the AC Charge start SOC that will be used by Luxpower. I still intend to enable AC Charge. Hope someone can answer the question what is Luxpower set value for AC Charge start SOC? My preference would be 10% < stop SOC.

Today, I had my first power outage. My alarm at the inverters went off. I checked the Luxpower software and it showed no power outage. I assumed that the alarm was from a momentarily loss of power and doesn't automatically reset. I manually reset the alarm several times, but the alarm would not go off. I checked the inverter and we were having a power outage. The LUX software just had not refresh in the last 5 minutes, so it showed no power outage. With the alarm I knew immediately that we were having a power outage and turned off the AC units. There was no flicker nor anyway for me to suspect that there was a power outage, except for my $10 alarm from Amazon.

I thought that I would lose internet during a power outage. I was surprise that I still have internet.

the inverter has a 5-minute delay to reconnect to the grid after it sense the grid. most grid tie inverter work like that unless you change the setting.

What $10 alarm are you using? Thinking maybe i should set something up like that

 

[Not Aerosmith]

Shouldn't EPS L1N and EPS L2N have a value other than zero? I had assumed that it was to show, if the loads were balanced on each leg of the power.

I have AC Charge stop set SOC=100%, so I am curious if AC Charge will charge the batteries from the grid when power is restored.
