Unlike consumer electronics, Deye does not typically provide direct public download links for firmware files on its official download page to prevent users from bricking their devices with incompatible software. To obtain the correct firmware:

: Email service@deye.com.cn with your inverter’s Serial Number (SN) and Logger Number . They can often push a remote update directly to your device if it is online.

: Check the support section of the Deye Home Storage app for available updates.
