I send you a photo of the inverter so you can understand its design. It is transformers that switch the DC voltage and raise it.
Thanks...
Hello Tony, thank you for your message. Well, the owner applied 220v to the output, causing a short circuit in the PWM and SPWM modules, as well as damage to the IGBTs and a couple of MOSFETs. There is no additional information about these modules. I have searched worldwide, even through images...
Hi Tony, thank you for your reply. Regarding the information, I only have the model and brand, Soltronix 1000p pure sine wave. They are inverters manufactured in China and sold in Peru. The issue is that many people have to buy another one because these have a limited lifespan set by the brand...
Greetings, I have a 1000W inverter, and I understand that it is not the latest in technology, but I want to repair it. The issue is with the SPWM module; it has a cross-linked processor, and its code has been erased. If someone could help me with more information about the processor and its...
