Luxpower monitor web dashboard !!

Starfrog

Hi, all Luxpower monitor users, as someone that is relatively new to this I have a few questions about what I see on the webpage dashboard about my Solar PV, Battery, Grid and my consumption numbers. On the first image, I’m confused by the PV saying its producing 2325 and yet I appear to be exporting 2579 to the grid ? How can I be exporting more than I’m producing ?. In the consumption box it states todays usage is 2.8kWh but I’m my Grid Import It says that Ive Imported 3.3kWH ? Shouldn’t that be lower ? Ive also noticed that a lot of times when my PV is high and charging the battery or exporting to the grid it shows my little home image as 0w usage for consumption ? I know for a fact that something is being drawn all the time so why does it not show it all the time ? Finally ive noticed that when i have a good PV production the battery often takes 2000+ charge but then when it gets nearly filled it drops to a steady 1000+ charge and the rest from the PV goes to export or house is that normal for it to do that for the final part of a charge ? Thanks for help   Note Today as of 22:00, I produced 16.67kWh from my PV solar, Imported 4.7kWh from the grid and exported 11.9kWh and consumption of 7.6kWh and my battery was fully charged and ran down to 10% I assume that pretty normal for a good sunny day right ?

Hi Starfrog.
Firstly, the reduction in charge rate when your batteries are reaching full charge is perfectly normal. All batteries do this.
Something's not right though with your consumption reading 0. First thoughts are an incorrectly placed ct clamp.
Can you post a pic of your graph at the bottom of the main page on the web portal.

Here’s todays view so far but the last photo is my old electrics (well be renewed during the renovation) and the only clamp is the one shown ive checked and it appears to be pointing the right way and ive moved it along a bit but still the same type of output. One thing I do remember is that when the installer put in the final bits of the setup there was an enphase box with two USB ports and some little green lights, he asked for a socket for it but i said there wasn’t one nearby and so he just attached it direct to the big switch on in the main setup which gave him the power of for the enphase box thing, now this might be why there is always a draw from my solar at night maybe ?

There should be 2 clamps, one on your pv connection to the consumer unit and one on the incoming supply from the grid.
The Lux needs to know your pv generation and your grid import/export.

EVandPV

Are you able to show a picture of the connections coming from the Lux ?
That would confirm if that's the problem.

Starfrog

well I can’t take a picture yet but surely as it’s showing my import and export and production then it knows what’s happening maybe the clamp that isn’t in the electric box is elsewhere ?

Could be, and it could be that one of the clamps is in the wrong place but I'd say that's the first thing that needs confirming.
There's clearly something not right if the Lux is showing no consumption and more export than your pv is generating.
It looks like the Lux is adding your generation and consumption together and reporting it all as export ??
That would suggest an issue with the ct clamps.

Starfrog

Well the generation and the export are about 15% difference so don’t think it’s adding them together 

EVandPV

The first picture you posted shows your pv at 3044 watts and your export at 3359 watts.
Clearly, you can't possibly be exporting that amount as your batteries weren't discharging at the time.
So the only thing I can think of is that your house is consuming 315 watts but the Lux is adding that to your pv of 3044 watts and incorrectly reporting it all as export. That could happen if the ct clamps are not set up correctly.
It could even be just that one or both of the clamps is the wrong way round.

There's an arrow on the clamps which should be pointing towards the consumer unit.

Starfrog

Good point I’ll have a look later

Your mains clamp Is pointing the same way as mine, but I quite often get 0 usage,  which I've always put down to the parallel units.
Also my export and import stats are roughly half of what they should be.. again I put that down to the parallel units
