+# Deye Hybrid Inverter Firmware
+
+Deye also stores the firmware for their hybrid inverters on the same server. 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.
+
+Update Procedure :
+
+1) Go to the IP address of the WiFi module of the inverter (stick logger), login : admin\admin
+2) On the left, click the Upgrade inverter item (the inverter itself, not the Stick Logger firmware)
+3) Select HMI file, i.e. MCU1-SG-Ver0000-C36E-CK.bin (MCU1 = HMI) as the first file, click upgrade. (time +/- 15 minutes)
+4) After rebooting, repeat the procedure, but now select the MAIN firmware file, i.e. SG_6K_MCU2_V4386-NR.bin (MCU2 = MAIN). (time +/- 15 minutes)
+
+FYI : the WiFi Stick Logger can also be updated by the Deye service (yet another firmware).
+
+If you have difficulty, you may need to powercycle the inverter before beginning the process.

+C362 - C369
+- Added Language 'Polish'
+- 'Low Power Mode<Low Batt' moved from 'Batt Mode' screen to  'Func Set4' screen
+- 'Low Noise Mode' moved from 'Batt Set2' screen to 'Func Set4' screen
+- 'Grid Side INV Meter2' renamed to 'Grid Tie Meter2' on 'Paral Set3' Screen
+- New setting on 'Func Set4' screen: 'Export Power Limiter' (appears to match the 'Max Sell Power' seting on 'Work Mode1' screen)
+- New setting on 'Func Set4' screen: 'Import Power Limiter' (the manual says this limits power from the grid, but has a lower priority than 'Grid Peak Shaving' setting.
+- New setting on 'Func Set4' screen: 'MPPT Multi-Point Scanning'
+- New setting on 'Port Set1' screen: 'off grid immediately off'
+- New setting on 'Port Set1' screen: 'AC couple Frz High'
