Wir haben mit dieser Firma nur schlechte Erfahrung gemacht. Wir haben für unsere PV Anlage ein Komplett Paket erhalten, mit 2 Force H2 Batterien + Force H2 MasterController (BMS) Nach gerade mal 2 Jahren zeigten die Batterien eine Störung an, doch die Firma (TST) wo wir die Anlage erworben hatten, verwies uns an den Hersteller Pylontech (China) Die veranlassten eine Abholung
zu der Firma EFEKTA. Wir erhielten dann von dort die Nachricht: Die Batterien haben angeblich eine Überentladung. Dort wären die Zellen aufgebläht und sie müssten entsorgt werden und wären angeblich nicht mehr transportfähig. Abgeholt konnten sie aber werden durch die Anfrage von Pylontech. Das einzige was wir erhielten war eine große Rechnung,- (von 455 € ) für die
Begutachtung von Firma EFEKTA. Angeblich sind wir selber Schuld. Der Wechselrichter sollte ja die Funktion regeln. Von wegen Garantie bis 7 Jahre??Der E-Mail Kontakt mit China war selten möglich. Angeblich war der Verantwortliche Herr LuWang ständig auf Seminar. Aber wir sind nicht die einzigsten die diese Erfahrung mit Firma Pylontech gemacht hat. Versehentlich erhielten wir auch E-Mails von anderen Kunden die von China zu uns kamen z. Bsp. aus Düsseldorf. Dort waren 3 Batterien ebenfalls aufgebläht. Hatte auch Fa. EFEKTA festgestellt. Also lieber nichts kaufen was von Firma Pylontech kommt. Garantieleistung null. Und das nach nach 2 Jahren.

I have a four battery pack of Pylontech US2000 batteries to give 9.6 kWh storage. Well within the guarantee period my Solarman inverter showed a series of overvolt and then undervolt conditions on one battery. Rebooting the suspect battery regained about 30% capacity shown by the SOC (state of charge) lights. My supplier UPS Solar have worked with me to try to bring the battery to a fully functioning state. They sent SD cards to assist the inverter but all that did was wipe the history! Eventually I removed the battery only to find the casing badly warped and distorted. The battery is scrap value only.
Pylontech take no responsibility whatsoever and refuse to replace the battery.
I am told there is no effective agency in the UK to handle claims.
I am stuck with three functioning batteries but paid for four.
DO NOT SPECIFY PYLONTECH
Find a company who cares!

I had 7 Pylontech Us2000c batteries having always lots of issues and errors. Due to the setting the effective availability of energy is much lower than what declared. After a couple of years they stopped working. Trying to reach their assistance is impossible, the batteries are trash now.

Expect frequent failures and no support from the UK agent when you submit a valid warranty request. Avoid at all costs, there are numerous, superior alternatives on the market.

We are a professional designer / supplier / installer in Australia and the response from Pylontech is non-existent and unprofessional. We have multiple systems with major degradation and cell imbalance issues with zero support to replace under warranty.
We will not be purchasing these batteries ever again.

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 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
