Peltontech stole my money
Ordered a Dewi pedestal from their site on 30 Nov 2025 Paid in full. Delivery was noted to be in 3 -5 days. It is 17 December and no feedback from them! I tried getting hold of them through the chatbot on their site, via Facebook messenger and a cell nr I found while searching for information regarding their business. No reply or feedback !!!!

Useless batteries! You will be lucky if it lasts more than 4 years
Useless batteries! You will be lucky if it lasts more than 4 years. Warranties worth nothing. Advertise that battery management system protect battery from overcharging - not true. Stay far away.

Not Honoring 10 Year Battery Warranties
I have a 6 year old installation in a 4 x 5kW Axpert Inverter setup with 20 x Pylontech US2000 Plus (And some new US2000C Top batteries in Cabinets for failed US2000C Plus Replacements). US2000 Plus Batteries started failing 1 or 2 at a time since 2 years ago with 900-1100 cycles on the batteries. Initially when installed in 2017 Pylontech approved the 53.2v Float/Absorption charge settings for the 10 year warranty and it was submitted to them by installer. 2 Years ago they replaced 2 batteries. The voltages on inverters was then adjusted by installer due to 2 batteries failing to a lower voltage 52.7v Absorption and 52.4v float, according to installer Pylontech's new recommendation is lower voltages to prevent overvoltage which still indicates the batteries are charged 100% full after the settings changed, so voltages seemed fine. Earlier this year another 2 batteries started to discharge faster than other's and Pylontech did not replace it and attributed it to overcharge voltages. How can 2 batteries in 2 cabinets fail out of 20 due to overvoltage but other's are fine (4 x 5 Strings of batteries, 5 batteries per inverter). Insurance declined physical or electrical damage claim and attributed it to wear and tear. Pylontech should cover battery usage (Wear and Tear) for 10 years correct ? If warranty not covering these batteries and insurance not covering it under electrical/surge no option exist to recover my assets ? Last week I noticed another battery discharging faster than other's and since Pylontech is not replacing I opened it to check if swollen. It was swollen as attached as the previous ones which they did not replace so I did not care I if voided the warranty by opening it. Today another US2000 Plus started discharging faster than other's. All battery cycles since installed 6 years ago are less than 1200 Cycles. Since day 1 battery monitoring was done (1st ICC then then swopped to Solar Assistant), battery voltages never exceed 53.2v and the past year never exceeded 52.7v after lower voltages set on inverters. Cut-off voltage done before reaching minimum voltages around 20% battery remaining on cut-off but low voltage according to Pylontech warranty replacement was not the problem, overvoltage was. Battery temps as per 3 months graphs indicates battery temps are within suitable temp ranges. I can only monitor 8 batteries at a time due to US2000 Plus limitations but I swop the monitoring console cable to a different set of batteries every 3 or 4 months to check if batteries still good. So 6 Batteries failed out of 20 and Pylontech attributes this to overvoltage and only 2 replaced. I will rather not recommend Pylontech for honoring their 10 years warranty at this stage. I also queried them dates of which overvoltages occured but they just ignored me.

PYLONTECH LITHIUM BATTERIES ARE USELESS AND EXPENSIVE
I have been told that Pylontech lithium battery is the best in the Market. THAT IS A LIE, PYLONTECH BATTERY IS TERRIBLE. THE BATTERY DOESN'T EVEN LAST FOR MERE 12 Months WITHOUT GIVING YOU SERIOUS TROUBLES. NO ONE WILL HELP AT ALL. I HAVE A 3000C WICH ALWAYS SWITCHES OF AS THE SUN GOES DOWN, I RUN MY SYSTEM OFF GRID. WHICH MEANS EVERY EVENING THERE'S NO POWER IN THE HOUSE, THIS STARTED WHEN THE BATTERY WAS MERELY 9 MONTHS IN MY HOUSE AND I HAD BEEN TOLD TO RESTART IT MORE OFTEN, BUT NOW THE BATTERY IS USELESS IN JUST 24 MONTHS YET WE ARE PROMISED A LIFESPAN OF 15 YEARS. STAY AWAY FROM PYLONTECH LITHIUM BATTERIES...

Very bad service
Bad service Good morning During March 2023 I bought a pylontec lithium ion battery up 5000 for R25300.00 , May 2023 the battery stopped working, I took it back to the seller ( Sunpower) , the seller said he will send it for repairs July I received a whatsap saying I must come collect my battery, I collected the battery when I reach home the technicians tried to connect the battery but it never worked I took the battery back to Sunpower and they said they will send it for repairs again , the battery is still with repairs , I sent message through whatsap on 2023-08-02 to the following numbers +27 81 339 5681 , +27 73 058 5558 and +27 62 520 3214 requesting them to replace the battery. They did not respond to respond to my request, on 2023-08-04 I went to Sunpower repairs and I explained to them that it looks like I payed money for nothing , the person in the repairs borrowed me a battery to use , when I reach home I called technician to come install the battery but unfortunately the battery never worked I payed money so something that is not working and Sunpower does not want to replace the battery, I request ombudsman to intervene on this matter, All I need is a new battery or my money back because their battery is not working.

Pylontech Batteries. Poor support service from Pylontech
We bought 12 x 5.5Kwh Batteries for a system. All went well until we found that 2 of the batteries have issues with the Software. We sent it to the supplier and they can't assist. Pylontech does not support them regarding the software updates. Pylontech does not have ANY support system in South Africa and they refuse to assist. They force you to use the supplier and pay them to come and do a software update. Pethetic. My Client is no busy with legal action against me because of this stupid Company and their arrogant attitude.

Pylontech warranties not honored.
My client's warranty was claim was rejected due to the Pylontech representative stating that the batteries were overcharged. We have taken all precautions and necessary communications options in order to ensure that the battery management can communicate with the inverter. Settings were done as per documentation provided by Pylontech and the distributor. How are we going to be certain that the bms is actually communicating and requesting the correct values when all the settings were as per manuals. Why did we not get an overcharge alarm? The physical damage is a concern and points to the product being inferior. Definitely not ever touching those batteries or recommending them EVER again.

Pylontech Batteries
Pylontech Batteries. We cannot complain about service, because there is nothing. Please do not buy any Pylontech batteries. The after market service is worse than worse. It is an endless struggle to have any support with firmware updates of any kind. There is NO softeware to assist you as a technician. We are trying to resolve issues through some very supportive solar companies, but still Pylontech is non existing in any support.
