Lux ac battery controller

My hybrid also states model 68262

Solarchaser

My parallel units are also 68262

So they all are.

I'm afraid your sudden jump in soc is also very familiar to uhome batteries

So what's a 73382 then ???

My single ACS model number is 73382 and shows a battery capacity of 172ah for my 4 uhome 2400lfp's. Is the battery capacity shown on the lux 90% of the full capability ? Average daily battery voltage when my batteries fully discharge at the end of the day is 52.5V giving 183ah so fairly close.

Thanks, that was the info & confirmation I was after. Seems the first and faulty unit my installer fitted was a SquirrelPod and the new one is actually the correct ACS 3600 that I ordered. So mine says 129ah for 3 batteries which equate to 43ah per battery which matches yours. 172/4 = 43. Now as to why the original one showed 3 x 150ah I assume that as the screen was broken the installer never actually changed the battery model. There was no way they could have done so it would have been at whatever was either on there before or whatever default is, 2 maybe which is Pylontech. Now why the agent & indeed Luxpower tech support couldn't just tell me this when I asked heaven only knows.

I've never seen another model number, so is that model number the squirrels then??

My pylontechs shows as 50ah each.
They are 50v batteries, so fully charged they are around 52v and fully depleted around 48v.
The rest of the time somewhere in between depending if they are charging or discharging

Interesting solarchaser, the uhomes have a BMS limit charge/discharge of 120A, unless they are at either end of the charge/discharge cycle when it reduces to 47A.

I suppose a process of deduction would seem to point in that direction. Luxpowers web site does say there are subtle differences between the two models so that would help to explain the differences in model numbers & firmware nomenclature. Although it really wouldn't have made one iota difference to me, they both worked I just don't see why the agent was cagey about the answer, I mean what do they have to hide unless trying to protect the installer?? Who knows, I have the answer now, the only outstanding one is the power draw which, as I saw it on two different units, I believe we all suffer just potentially you haven't noticed it OR the Pylontech BMS is just better at shutting down. Within this very long train I did find someone else who had noticed that their Uhome was dropping below 10% down to 9%???

You live and learn. I should have done more research before pulling the trigger and maybe I would have made different choices. Just at the time trying to get any installer to even give me a quote was a nightmare. The one I went for were on the MCS approved list, the quote did seem to be within the norm however from that point on well.............................

Weird Sudden Battery Discharge

Lux AC 3600  and two Greenlinx batteries (6.4kWh) installed just before Xmas.  Over the weeks I've been getting used to all the control settings, and interpreting the data .
I noticed a weird and very sudden discharge of the batteries the other day.
The batteries went from SOC 44% down to SOC 0% in 4 minutes !!  Yes FOUR minutes to dispense of approx 2.8kWh.   . . . .  and usually discharge stops at 10% so it was weird for that too!
Nothing much was on in the house.   In fact we don't possess anything that could consume that amount so quickly.

Might anyone have any ideas as to what could account for this???  Any hypotheses appreciated as food for thought.  I haven't messed with any "forced discharge " settings but  I did see a UFO in the sky 10 minutes before.  (Jus kiddin)



Thanks  SolarPolar

Does anyone know why my Pylontechs (4 x 2.4kW) stop discharging at around 30%? Most days it is not a problem because my other PV system also has an additional 6.7kW storage but on very grey days we occasionally revert to grid during peak rate in the evening which is obviously not ideal.

Lux on-grid, off-grid discharge & stop discharge settings are at 10% cutoff as well as (Charge Priority) Priority Charge Level but the lowest achieved before the house reverts to grid was 28% SOC, normally its 30-32% so I seem to have far less available than I should (6.7kW @30% max usable instead of 8.6kW @90% usable).

I've tried emailing Lux & Michael at Home Energy Group (my supplier, sister of Big Green Beard) but no response from either.
