Lux ac battery controller

Go to maintain, click Read All then scroll to the bottom and click reset to default. I too ran into that and it seems to be something set in the background. The reset solved it for me

Hi all

First post here

128 pages is a long but am going to share my experience of the Luxpower ACS 3600. As others have said the DC to AC inverter draws +-50 watts in standby 5 x more than the 10w claimed by Luxpower. As a result overnight I can see up to a KW of my free solar power energy wasted only for it to then decide to suck in expensive power from the grid to top it up. Apart from doing a remote firmware upgrade the local agent has been like the proverbial chocolate teapot as far as answers go. What i did get from them is that if your system is connected to their cloud server any changes you make will be reset to default after a reboot. As for the installet well.....

So I now switch mine off evert night and only power it back on if it looks like it will be a sunny day. I have a remotely operated 125A circuit breaker coming from China that i will install between the battert and the inverter. This way I can set timers and operate remotely without shutting down the inverter. I have also isolated the 3600 from the internet and now change all settings from the app and now all settings are kept no matter what. Had i known that support would be zero and that it would waste energy I would have looked for another solution.

Oh and to add this is my second unit, the first, supposedly new, fitted 25/11/22 had a faulty screen and scratches. The new one has a totally different model number showing in the dashboard and had older firmware. When i queried this model discrepancy with the agent I was told "we only share that info with the installer" ????

Hi

Just out of interest, in the App, why don't you configure a "Charge Priority" time i.e. between 00:00 - 06:00 for example.

It then won't discharge the batteries to cover your house load - theoretically house base load at this time may be at it's lowest.

In my experience with a Lux Hybrid 3.6K (completely understand you're using a different standard ACS inverter), the standby currently draw by the inverter is really low, no where near 50w, as my nighttime base load is 85w as indicated by my IHD, although the graphs on the Lux App are a little higher.

Hi, thanks for the input but perhaps i didn't explain properley. The DC to AC inverter stage draws power from the battery even AFTER the discharge cut off value. There is no power draw from the house, you can see this clearly from the logs. I first noticed it when i set my discharge cutoff to 20%. Whilst my batteries claim to have a DoD of 10% I prefer to limit the range between 20-80 for longevity.

So if I set the cut off at 20% by next morning with ZERO draw to the house it has gone down to +- 10-11%. Once the battery voltage hits 49v then the system starts to pull in +-330w from the grid. So it wastes 10% in internal losses and then compensates by costing me money. Now yes I am aware that inverters have internal losses and if it were 10w then over a 10 hour period I would lose 100w. My storage is 7.2 kw so 10% = +- 720w.

I apprecite the suggestion but can't see how setting the charge priority is going to solve this at night or on an overcast day. Charge priority says when there is solar charge the battery first and then supply the house.

Solarchaser

Thats definitely not what my Acs do.
When they hit 10%, they sit there.
No draw of power, no drop in %

The only time they will draw power again is if I switch all off, at that point it can decide the % is lower and take a charge to top up.
I leave mine on 24/7

And that is why I reached out to the agent to try understand why mine is doing this. I sent them a video showing the logs, showing what was happening and then they just went radio silent?? Not a very good customer experience ??

Out of a matter of interest what firmware is yours on? I am running BAAA-1517

Solarchaser

I'm running parallel inverters so my firmware will be different to 90% of people on here, but lots are running a single acs, like EVandPV. 

I found the uk vendors to be useless.
I email lux direct info at luxpowertek dot com with any issues.

Yeah, i got no response from them either. In sequence i tried

1. Installet
2. Luxpower dot
3, local agent

Seems like if there is a hard to answer question they aren't interested.

Sharp contrast from my experience with Myenergi. I have one of their EDDI power diverters and can honestly say I have never had such good experienece from a vendor before and I am in the electronics manufacturing industry

Solarchaser

They have generally been good, though in the last week or so, not so much.
Apparently the bms in both my stacks have went faulty at the same time.... aye!!
Myenergi have been good.
The app is good, with great refresh rates, though it could be much better with a few tweaks. 

I do love this display (10 mins ago before my cheap period ended)

Obviously there are many pages before this but here is an example. The discharge cut off was set at 20%. You can see the voltage here dropping until it reaches 49v and then it starts to pull in power from the grid. You can also see that there was no draw from the house (last column). So bye bye free solar power, hello pay for grid power.

Hi I run the ACS 3600 and like solarchaser dont get the issue you have spoken about, once down to the battery cut off at 10% or higher, if they havent exhausted, when my cheap rate cuts in, i see no power draw from the battery, or indeed power pull from the grid. My firmware is BAAB-0706.

Thanks for the feedback. It is random. At 10% DoD I sometimes see what you see, the battery goes orange and then just sits there at 10% until charging the next day where it will go green again at around 15%. Other days it will do as shown in my picture above.

It would be interesting to see if you set your discharge cut off to something other than 10% e.g. 20% if you saw what I am seeing. If my batteries were LiP04's then I wouldn't care that they were going down to 10% as they can cope with that and still give over 5000 cycles but for longevity LION's last longer with a more conservative DoD of 20%.
