Lux power charging from AC issue

Featured Replies

I have searched Google and have not found much on this issue 

Charge from AC

This inverter will not charge from as unless you push the quick charge on the main screen then it seems to only charge for X amount of time or Wats and stop charging .

I have tried every setting I can think of to get to to charge after dark  from AC to boosted the battery between load shedding with no success .

It charges from solar so charging is not an issue .

It's set to charge to 100% from solar though the day  which it does .Then into the evening to discharge the battery to 80% which it does.  Now it set to charge the battery up  79% from AC at night after load shedding for the next load shedding schedule through the night but it does not .

the battery can be 26% and they will stay there till sun up or shut down with early morning load shedding which is frustrating because you have to wake at in the middle of the night to push the quick start button one the main screen or the system shuts down due to low battery with next early morning load shedding . 

the pics is were I ended up after trying everything to get this inverter to charge from AC .

what am I missing? 🤔

Use more than one start and stop time time during the same day. Your start time is later than your stop time as it spans across 2 different days.

Start it say at 00h01 to 06h00 for timer 1 and then add a 2nd start at 18h00 to 23h59 and see if it makes a difference. The idea is to start at the start of the same day.

Tried what you suggested not working .

There must be something very wrong with these luxpower inverter software as it will not follow any setting regarding AC charging from % or volts or both . The only way this inverter will charge from AC is to push quick charge button on the main screen . .

Again am I missing something as it 3 luxpower inverters that I cannot get them to charge from AC with pushing quick charge so it can't be hard ware .

Well normally if you followed the manual and any suggestions and it does not work as it should one would return it to the seller for checking of all the functions. We know any product can be dead on arrival or very ill. QA is no longer a strong point these days. 

Are you sure these settings are correct. Something looks odd to me. I don't know this inverter and just looking at the level of the settings.

You can choose between soc% or volts  it is set to follow only soc % setting which it does follow the on grid EOD % at 80%  but not when it comes to  charging as I said I will charge if you hit the quick charge button and as I said there 3 units that I'm monitoring that has the same issue can't think all 3 are faulty . 

Is there anyone that has got this luxpower to follow AC  charge setting,  if there please share your settings

So you have 3 of the same inverters all doing the same thing, are they connected in parallel, how much batteries is connected to the system?

No these 3 inverter are on different locations. 

2 were installed by an installer and later solar was added by someone else but both places after the solar installation the owner did not see improvement in there electricity account so I was ask to check there setup and found the take load together was not activated so problem solved there . 

3 inverter the owner installed his set himself with his son in law which is an qualified electrician . They took at the setup and was lost  so I was ask to help .

There idea was to use a few % battery into the evening to save on electricity so 20% used was safe amount for only an 5 kw battery stop discharging at 80% in the evening worked perfectly 

All was working well till load shedding . So now with load shedding if the battery dropped under 80% to say 50% according to the setting In my first posted it should charge to 79% from AC and stop it does not it stays at were ever it stopped after load shedding till sun up .

In this pic above  you have under AC charge , battery soc or time or both mix if I set in time only it will  then charge from AC the batterys up to 100% and discharge back down to 80% and the loop goes on all night  not good .

 

 

In bottom pic if I choose SOC it should follow the bottom two underlined in red.  If I choose  SOC and TIME  it should then follow AC charge start  stop time and the two bottom marked  in red  and it will not charge battery from AC at all if using this setting

There definitely must be something wrong with either that specific Luxpower model / batch / firmware to all behave in the same way!

Hi. 

It will only start if SOC is below the "AC Charge Start Battery SOC(%)" But then the  "On Grid EOD SOC(%)" setting must also be below the "AC Charge Start Batter SOC(%)" else it will start using Eskom, but not charge battery.

My settings:

Discharge Cut-off SOC(%): 25%     (For shutdown if no eskom and no PV to protect battery)

On Grid EOD SOC(%):   35%           (Start using eskom, if battery low and no pv - early morning just before sunrise)

 

AC Charge Based On:    SOC and Time

AC Charge Start Time 1:    15:00

AC Charge End Time 1:      17:00

AC Charge Start Battery SOC(%):   80%

AC Charge End Battery SOC(%):     95%

So what this last batch of settings does is: if the PV does not charge it to at least 80% @ 15:00, eskom will charge it to 95% until 17:00

 

I believe you need to lower the "On Grid EOD SOC(%)" setting (where you want to run off eskom and not charge battery) and raise the "AC Charge Start Battery SOC(%)" (where you want it to start charging)

Yes thanks that's the part  I was missing. 👌

The start charge is the trigger .  So  the battery  soc% has to be lower than the AC battery start charge soc % for it to trigger the charge from AC . 

Lucky the guy has load of tree around his house and so his system only start to generate around 11 so his battery soc  is still 79% so set in 80% start charge to 85% and it did charge from AC to 85% 👌 .

So working now . So now I can do a setup to get this inverter working to his exspection 😀
