Lux ac battery controller

Hi there,

yes I did email them then but did not get a reply - perhaps a retry might be sucessful.

 Thanks

So, I contacted Lux directly again, who bounced me to Infinity Innovations who only do tech support for Installers.

Has anyone broken this loop?

Only suggestion I have is to try the Facebook group, explaining that you're stuck with an unhelpful installer - there may be a friendly installer on there willing to set it up for you

Eventually it was done. 

My installer was doing all the right things, but the UK ditributor was not pressing the correct buttons.

Up and running now

Ah, Uhome batts must work differently to Pylontechs.

Hi all, been a while!

After much messing around (for weeks) by Infinity, I finally cracked and got in touch with China. Looks like my setup was not only installed wrong from the beginning, but when their own man came out, he wired them up wrong as well.

China to the rescue, very helpful, even with my daft !!!!!! questions. I now have 2 x 3600ACS's paralleled correctly and 2 x 3 batteries wired in parallel as well.

 I have LFP-2400's (2 sets of 3). Wired as below and fully working now, not one error since the Chinese explained how to do it.

OK I've now worked out the the "wifi module" is the little thing that looks like an aerial.

Still no success though.

I have never managed to get the newer batteries to connect. The old USR ones were easy. New ones, nothing ever

I think you'll find that that's about right because you lose about 10% converting AC to DC and then you lose another 10% when you change it back from DC to AC.

I've just checked and my battery SOC was  95%. Two minutes later it was 90%. Then, another two minutes later it was showing that the panels are producing 439w, the house is using 307w, 35w is going to the battery (which is now 93%) and 90w is being exported to the grid.

Curiouser and curiouser innit?

 I wonder if Lux are playing about with it remotely.

I caught them playing with mine overnight about 3 times. Deleting dongles, adding a strangers dongle (which they then couldn't remove from the account, and even changing them from parallel to single and then some other weird setting.

One huge complaint to China, problem fixed. Don't bother with the UK.

Great you have made progress.

Shame ( or worse ) about the UK support!

Very much worth a complaint and going public IMHO!

Taking Control,

Call me paranoid if you wish, but with all the stuff going on in the world and the Internet being quite a nasty place, I would like to know if anyone knows how to take control of the LUX inverter and battery system: i.e. not send the data to the LUX servers which I assume are in China and connect to them directly on my home network

Hi Madswitcher,

I don't think your paranoid. How do you think the Israeli's and Stuxnet destroyed the centrifuges?

My Growatt inverter goes via Grott proxy now, all internet access inbound to it is blocked.

Lux inverters will be next. To be honest I get much better info from my Luxpower integrations in Home Assistant so I think I will block outside access once I get home and check the firmwares on the inverters and the 6 batteries.

I intend to install and run Homeassist and use that to interface with all my home IoT as recommended by another member. However all you need to connect and full monitor your inverter is an old Android Tablet or iPad with the Lux app installed and them do a local connect to the inverter dongle. This is a direct connection, with no need for the inverter to talk to China. The app has ALL settings available in this mode.

I've got my two inverters on a 'guest' network, which I guess helps a little. I'll look into Homeassist, but do the manufacturers not need some access for warranty purposes or s/w  upgrades?

Read my posts mate. They played with my inverters over a few nights and properly screwed my system up. If I said they'd done it to be a little bit vindictive, I don't think I'd be far off the mark. The system was installed incorrectly, configured incorrectly, then they sent their 'top man' to my house to check it, he confirmed everything was 100%. It wasn't. I had to get China to help me with wiring diagrams, reconfiguration and actually having both inverters paired against the same continent.

One was in Europe, one was Asia. Hence why one was stuck on GMT+8 (I realised that no matter what I did, the inverter kept reverting to China time).

I have dealt with them - as have plenty on here - and we all have the same opinion. Once they have your money, bodgit & scarper.

I'll be honest, the Chinese Lux support is top notch so far. UK side.....

If I ran all those companies and I had integrity and I read this forum I'd be ashamed of myself and my business.
