The batteries began to fail after only about two years. My engineers tried many different ways to fix issues - the inverter (SOLIS) kept sending me reports of problems with code 2015. Then we had other codes and the batteries kept shutting down. My engineers tried many
times to raise tickets with Pylontech, but no answer. The call centre don’t even answer and I’m left with out batteries on my solar system fitted only 3 years ago.
I’m now having to replace these dud batteries at my own expense at £1,000’s
AVOID THEM IF YOU DON’T WANT TO GET SCAMMED BY CHEAP RUBBISH BATTERIES

Ik ben zeer tevreden met de Pylontech accu's. Ze zijn erg goed schaalbaar en makkelijk te installeren, wat een groot voordeel is bij uitbreidingen of aanpassingen. Het enige nadeel dat ik heb ervaren, is dat het een uitdaging kan zijn om onderdelen te verkrijgen als je iets mist. Dit kan wat frustrerend zijn, maar het doet niets af aan de kwaliteit en gebruiksvriendelijkheid van de accu's zelf.

Had solar panels installed a few years ago with 2 2.4kwh pylontech batteries. I filled out the registration for the extend warranty after they were installed. The first battery failed around a year later of which the installer replaced. The second battery failed around 4/5 years later. Just but looking at how it had swollen you could tell that it had failed so I contacted pylontech about a replacement under their warranty. Well several emails and months later after them requesting that I make up a lead and install software to download a fault diagnosis for the failure that I could not achieve, then them sending me out a lead that I still couldn’t connect to the battery due to most likely it had completely failed. Well after all this messing about they then informed me that it’s not their problem and that I need to contact the inverter manufacturer about the failed battery. If this was the case then they should have clearly stated that many emails and many months ago or are they just trying to fob me off.
DON’T TOUCH THESE BATTERIES AND DON’T LET ANYONE INSTALL THEM ON YOUR SYSTEM AS THEY WILL FAIL AND PYLONTECH DON’T HONOUR THIER SO CALLED EXTEND WARRANTY.

I bought two US 2000 batteries 3 years ago, one of them went out, unfortunately for fear that it would catch fire I opened it, the batteries were completely swollen, the assistance in Italy did not consider replacing them because they said that they had lost the warranty.... which brand to avoid

I have a Redback SH5000 inverter with 2 x Pylontech US2000 batteries installed by SAE group in 2019.

These batteries come with a 7 year warranty and have been installed for less than 5 years. Both batteries have completely stopped working and one has ‘swollen’ which makes it potentially dangerous. I have just been informed by Redback that warranty approval by Pylontech is expected to take up to 6 weeks, only after this time can they organise a replacement leaving me with no battery backup likely for the next 2 months +. One of these batteries will be the second replacement after failing around 1 year after install and being replaced under warranty already. Seems to be a high rate of failure on these products hence extended wait times for warranty replacement. Given the chance again I would not have splashed out thousands of dollars on this brand.

Returned 2 faulty 11 month old batteries to my supplier 2 months ago and haven’t had a replacement or refurbishment back. Pylontech’s 1st excuse was, they’re moving premises, 2nd excuse, we can’t find a courier to pick them up, 3rd excuse, our premises are not big enough to pick all the batteries up. I’ve never heard so many excuses in my life. Customer service is an absolute joke.

Their agent in Thailand helped me with getting a replacement battery. I am very happy with this company.😃😀

Battery 9 months old and has stopped working i have 2 us5000 the second working fine. I have made a claime through my supplier but pylontech are dragging their feet no replacment as yet.

Ich nutze seit nun ca. 2 Jahren einen EASUN 10KW 3Phasen Solarumrichter mit einer 48 V Akku-Bank von Pylontech (3 x 3000 W, 2 x 5000 Watt). Die Akkus können über einen eigenen Bus untereinander kommunizieren. Über die vorhandene RS232 Schnittstelle wiederum kann die Batteriebank mit dem Umrichter kommunizieren. Die Anordnung funktioniert bei mir hervorragend im kontinuierlichen 24 Stunden Betrieb. Mit dem PC-Software-Tool Solarpower können im EASUN Umrichter alle erforderlichen Einstellungen auch im Zusammenhang mit dem Akku-Einsatz vorgenommen werden. Bislang bin ich sehr zufrieden mit diesem Arrangement.

Love pylontech batteries. Always work just fine.

Don’t let your solar supplier fit pylon tec 2000 batteries I was supplied three in sept 2019 and they are not working at £1500 each that’s £4500 . I’ve emailed 3 times with no response if anyone knows of a contact in the uk please let me know
