I have green lights on all 3 indicating they're all discharging and capacity is now at 150ah.
Your SOC won't change if all 3 batts were at 73% but your capacity will, of course.
Did you balance them before powering up the Lux ?

Yep I see 150,all looks OK! 
I didn't balance them though - would they all get to 100% overnight? Or do I need to balance? 

If they're all roughly the same SOC, (same number of green capacity leds) you don't need to bother balancing them.
If one is way higher/lower than the others, best to balance them first.

wow, that's quite the set up doesn't sound like they're working very well in tandem...

How are you guys doing with grid import accuracy? even if i'm meant to be 100% on battery, i still seem to be pulling 40-60 watts consistently from grid. is there no 'adjuster' here? the clamp is on fine - just it's readings are always just so slightly off but enough to cause an import. i'm trying to get rid of the grid!

Strange. 
Mine got updated to BAAA-0E0E and I haven't seen any of that since.
Just the usual bit of import when the ketttle, oven or shower was on.


Just added a 3rd Pylon so shouldn't see that either now.

Would you mind doing me a massive favour? could you show me how your clamps are plugged into your grid / PV cabling, and which way around the arrow faces?

This whole 44w import is really annoying me - it's not much but at times like right now my house is using only 400 watts or so, well within the battery output limit set, but i'm still importing 41 watts. the lux monitor shows 0 being pulled from grid and 100% from battery, but my electricity smart meter is saying something else...

sorted out the 40w import issue!

Yeah, I saw that before I had the Lux firmware updated although it didn't seem to work on mine. The firmware update sorted it though.

Combination of both solved it here... at least there's a solution! I'm seeing lovely 0kwh imported plots (or lack of) in my usage charts now.

I think the Batteryview app can tell us Lux users how many cycles we've had from the Pylons, a feature currently missing from the web portal data.
The figure highlighted in this screenshot would appear to be in the right ball park for my system and if I'm not mistaken, shows the total number of charge/discharge cycles.



We've had the batteries for 95 days so that would be about 1.3 cycles per day, which seems about right.
Strangely, there is a heading for cycle data but the figures bare no relation to our system, there's no way it could have done 2043 cycles in 95 days !

Do any of you folks' LUX buzz? Mine has a quite distinct buzzing sound when idle...

Not noticed any noise from  mine.. perhaps my hearing aids don't pick up that frequency ?

EVandPV

Can't say I've noticed it either.

A cooling fan maybe ??

Yeah under about 400w of charge or discharge both of mine buzz, above it they are quiet, idle they are quiet.

Still no update for mine, getting rather disappointed.
Noticed that after about 50% charge going by battery lights, the lux tell me they are 100% charged... hmm.

Also when i set them to 90% discharge, it sets the controlling battery to error (red light on) so ive set them both to 85%.

Really tempted to go back to the sofar at this stage, at least i could believe what it was telling me.
