Hello everyone,
I wanted to share my negative experience with POWMR inverters and their customer service. I initially bought a 12kW 3-phase hybrid inverter, which failed after just seven days of use. It failed during the night when the load was definitely less than 1kW. My mother heard a loud noise, indicating something exploded inside the inverter, causing the entire house to go dark. Naturally, the inverter stopped working.
I contacted the seller on AliExpress to claim the warranty and requested a replacement unit, but he refused and blamed me for the failure, alleging we had mishandled the inverter. He insisted I pay €106 for shipping the inverter back to China and promised to cover half the shipping cost upon receipt. I sent the inverter back with a tracking number, and 28 days later, it was delivered, but the seller claimed he never received it. Even after 10 days of follow-up, he refused to provide a replacement, reiterating that they hadn't received the inverter.
I reported the issue to AliExpress customer service, opened a dispute, and uploaded all the necessary proof, including tracking information and videos of me packing and sending the inverter. Fortunately, I received a refund after the dispute was resolved, but the seller never refunded the shipping cost as promised. Instead, I asked for at least half of the shipping cost back in the form of a Wi-Fi module compatible with another POWMR inverter I had, a 10.2kW single-phase model, which I mistakenly bought earlier due to some confusion about my house's power requirements.
The Wi-Fi module arrived faulty. When I contacted the seller, he accused me of damaging the communication board by plugging the module into the wrong port, which was impossible since there were only two ports: one for the battery management system and one labeled "Wi-Fi." Despite sending video evidence of the module not working, he continued to blame me and asked me to open the inverter and record the communication board, which I refused.
Ultimately, I decided never to deal with POWMR products again. I switched to a DEYE 12kW hybrid inverter for my house, and it has been amazing with zero errors. Unlike POWMR, which couldn't effectively combine solar, battery, and grid power, the DEYE inverter manages this seamlessly.
For instance, with the POWMR inverter, if my house consumed 11kW, solar produced 4kW, and the battery (at 100% state of charge) could discharge 3kW, the inverter would attempt to pull 7kW from the battery, causing an overload and a complete power shutdown. The DEYE inverter, however, can specify the max discharge power of the battery and combine solar, battery, and grid power efficiently. If solar and battery are short by 3kW, it pulls the remaining 3kW from the grid, preventing any power disruption.
In conclusion, my experience with POWMR was disappointing, and I highly recommend considering other brands like DEYE for reliable performance and customer service.
