So far the http://47.254.36.66/0_5407_1/ directory has been identified, but there may be others. +The firmware located here has been confirmed to work on the SUN-3K-SG04LP1-AU-24V and SUN-5K-SG04LP1-AU, however based on naming conventions, it seems like this same firmware is used across a lot of the hybrid inverter models and regions. + +There are two types of firmware files in there, one for the HMI (display) and the other for the main firmware. +Examples: +Main: SG_5K_MCU2_V3384-NR.bin +HMI: MCU1-SG-Ver0000-C366-CK.bin + +Based on information in this forum thread: https://powerforum.co.za/topic/12655-deye-inverter-latest-firmware/ +It is recomended to update the HMI first, followed by the Main firmware. Generally the HMI firmware update doesn't result in the inverter shutting down the outputs, but the Main firmware normally does. + +The update process is fairly straightforward. Deye's instructions can be found here: hybrid-inverter-info/LOCAL UPDATE INSTRUCTIONS.pdf +The default login and password for the solarman dongle is admin/admin. +I found that one of my inverters needed to be power cycled before it would accept the new firmware. +And sometime the firmware upload would start again after the initial upload unless I unplugged the solarman dongle. + +## Summary of HMI firmware changes (see photos here hybrid-inverter-info/HMI-photos) + +C362 - C369 +- Added Language 'Polish' +- 'Low Power Mode
