LuxpowerTek Avis 

I have a lux powertek hybrid inverter installed last year, it has not been without it's issues. This past year we have had several erratic episodes where the inverter seemed to have a mind of it's own. Despite making no changes in settings ourselves, these seemed to change causing the inverter to do things we did not want it to do. At times I spent several hours in the loft resetting the system, reinstalling passwords and resetting the WiFi dongle only to discover eventually that it was as suspected all along, a problem at the manufacturers side with server and software issues. Now all of a sudden my batteries are charging from the grid despite AC charge being disabled in settings. This has only been doing this since the last software update. Previously SOC cut off set at 5%, batteries would only recharge next day if sufficient solar energy, now they are consistently drawing grid power every day to top back up to around 8%. Why has it just started doing this spontaneously?? Nothing has changed in my settings.

I contacted Lux in the UK, along with their UK authorised suppliers Infinity Innovations who repeatedly told me they dont speak to end users/consumers and to direct any concerns through the installers who at times are none the wiser.

These systems are not cheap, and once installed should give peace of mind re their operation, not repeated erratic behaviour causing a great deal of inconvenience for the end user/consumer. After care in the UK sucks and is almost non existent. This needs to change Lux/Infinity Innovations, otherwise people will look at rival manufacturers if they offer a more reliable product with better after sales care.

Addendum: So today 17th December 2024, I finally received a response from Luxpowertek...over a year to respond as my original post was in December 2023. Whilst apologising sincerely, there has been no offer of support directly from Lux, only a suggestion that I email marketing, Will I have to wait another year for you to get back to me? This post speaks volumes about What Lux thinks of it's UK customers. My inverter is still behaving erratically, if this was a car behaving like this I would have handed it back.

The Luxpowertek LXP 3600ACS is good at its job but unfortunately creates such bad EMI (Electromagnetic interference) that the use of the mid ‘20s Tivoli Audio One FM radio is nearly impossible. Neither the installer nor the manufacturer accepts this but the issue has only occurred since installation. It does not affect other makes of FM radio that I own, so if you don’t own a Tivoli Audio Model One you may be ok.

I am a person who just wants technology to work. I chose Eco Renewables (review of them also posted today) to install my battery to augment a previously installed solar panel array and Eco used a Luxpowertek inverter with the battery.

I had problems with the inverter communicating with the app on my phone, pretty fundamental to have this working when you want to track and manage solar panel and battery performance.

I can't say enough about the technical support by email I suspect came from China. It was prompt, swift, patient and professional. That you will have technical teething problems is almost a given, good technical support you hope for. I got it with Luxpowertek to my relief, I hope this is useful information for anyone like me who likes technology but relies on good support to maintain it.

As for the kit, very solid performance - no complaints there. And the app is great for tracking and managing solar panel and battery performance.

Thanks,
Jim
