Dear customer,
Regarding the recent appearance of products in the market that resemble the MUST inverter, if you have purchased a product with the same appearance as shown in the image below, we kindly remind you to be cautious as this is not a product manufactured by us. Our products hold design patents, and the body of our products contains a production serial number.
For products not manufactured by MUST, we cannot provide warranty services. Please ensure that you identify the MUST brand. Thank you for your support!
