Lux ac battery controller

It’s worth a try but maybe our installers would have more insight into what changed with the settings

As a pure guess I would think nothing has been changed .. except the fact that we can no longer see what is set

Which is a great pity because I was working on the reactive power settings and had just found a setting which caused the imported power to be zero for most of the time when there was no solar generation.  It used to have an import of 50 - 70W all night.  I got this down to virtually zero (+-5W) by adjusting the reactive power.  Unfortunately I didn't get round to investigating the imported energy when the solar starts up - this is between 40 and 50W during daylight hours.  I'm measuring this using the smart meter's IHD.  The Lux app always shows zero imported except when charging or the load is too great.

The reactive power settings are not available on the app.  Perhaps I could try adjust the phasing of the PV inverters instead, but that will have to wait for a while.

What firmware are you on Dave ?
I had the same issue under some previous firmware versions but it's been fine under the latest version, BAAA-1111.

The firmware version is BAAB-0303. It's the version it came with.

Might be worth emailing Luxpower to see if they can put you on BAAA-1111 in that case.
I know of at least one other member of this forum also on that version and doesn't have the import issue.

I'd agree with Scott,  being on an old software version won't be helping.

However it sounds like the lux has no actual connection to the aoboet batteries, if its only reporting soc via voltage.

Going by Daves description of the behaviour of the batteries,  it really sounds like there is no communication.

Is there a patch cable in the 485/can socket on the inverter?
And if so, does it connect to the first aoboet battery?

Ok so i got home and had a look for the second clamp and this is what i found the clamp was wrapped around the brown wire and i took it off and turned it so the arrow was pointing the other way and it went down to 2w which is better than my usual 30w in the middle of the night but then it was showing no consumption what so ever and the PV is now in the middle of night sending 57w into he battery ? Now if its doing that or not is up for debate as maybe its needed reset ? Can i reset it ? I placed the clamp back on the normal way i found it and picture of the lux monitor is now what i have ? Maybe it takes time to sort it self out ? I’m really at a lost with this now as i just want it to stop feeding 30w from the PV in the middle of the night !

It looks like in the last picture the clamp is on the right wire and pointing in the right direction,  both clamps should point towards the solar panels essentially. 
However your clamp does not look like its closed completely,  it needs to be closed to complete the magnetic field so it can monitor the current flow in the wire, you should hear a firm click when it clicks closed.
Might just be the angle of the pic tbh.

From an interference point of view I'd not be overly happy that it's running in and out the other wires, i don't think the clamp wiring is screened so you will probably pick up on eddy currents as it runs through other wiring.

I'd pull the clamp all the way to the right hand side of the box, coming in to the right of the earth wires and then pull it forward swing it in to the brown wire going around the earth's and avoiding the neutral all together.
Bad sketch attached 


It may be worth giving the wire a couple of wraps of tinfoil as a test to see if its picking up interference,  but obviously be very careful in that box with tin foil.

The last picture is how I put it back I can’t physically place it anywhere else as the cover won’t fit on. I need to get the installers to reset it remotely or something as it seems just pulling out the two clamp wires at the lux box and then putting them back in seems to screw my whole settings up.
