My experience with PowMr after-sales…
My experience with PowMr after-sales service has been extremely disappointing. I purchased a PowMr inverter in May 2026. It was installed in June and initially worked as expected, but after approximately three months it suddenly failed with Fault 08. That is when the real problem started. I contacted PowMr and cooperated with virtually everything they asked me to do. I provided detailed information about my installation, completed their technical failure form, sent numerous photos, and even opened the inverter at their request to inspect the internal components for visible damage. Instead of receiving a clear warranty solution, I was repeatedly asked for more information or to repeat information I had already provided. At one point, after I had already uploaded the completed failure form through the AliExpress chat, I was told they could not view it and was asked to send it via WeTransfer. They only provided the general WeTransfer website, without a recipient email address or specific upload link. This process went on for weeks and took a completely unreasonable amount of my time and energy. Eventually, I stopped trying to resolve the issue directly with PowMr and contacted AliExpress customer service myself. After I opened a dispute through AliExpress, PowMr contacted me asking me to cancel the dispute. I refused because the warranty issue had still not been resolved. AliExpress ultimately handled the case. I was able to return the defective inverter to an address in the Netherlands, although this cost me €22.50 in return shipping. My refund has now been approved and is being processed. My main criticism is the after-sales and warranty support. When a product fails after only about three months, a customer should not have to spend weeks repeatedly providing information, filling out forms, taking photographs and even opening the product to inspect its electronics before receiving a concrete warranty solution. I cannot say whether this process was caused by poor communication, poor organization or deliberate delay. I can only describe my experience: getting a warranty solution directly from PowMr was unnecessarily difficult and exhausting. In the end, I had to involve AliExpress to get the matter resolved. If you buy from PowMr, I strongly recommend keeping screenshots of the original listing and saving every message, photo and document in case you ever need to make a warranty claim. Update: Following my Trustpilot review, PowMr contacted me personally, apologized for the poor support and promised to improve their customer service. They also offered a discount on a future purchase. I appreciate their response and the fact that communication has now improved significantly. I also feel more confident that I can reach them if I experience problems with my current inverter 12Kw/48v which is great. My original review still reflects my experience, but I believe it’s only fair to acknowledge this positive development.
