Growatt SPF 5000 ES Firmware "Send: Start!"


Recommended Posts

Posted

Hi everyone,

I recently received the latest firmware (F2809_SK040.06_20220104_A.bin and F030_SK041.06_20220104_A.bin) and ISP tool 4.21 from Growatt support in China and tried to update the firmware but the ISP Tool keeps on sending "Send: Start!" endlessly and my inverter is not starting nor the firmware is being flashed.

I used to have the firmware version 040-05-701 and 041-05-701 but after the tool failed to start the inverter I can now see 008-00-316 and 041-05-701 and the inverter is not working.

 

Need some help please.

Did you follow the precise instructions in this link?
Also, your inverter should be only on battery power when doing the flash. Solar disconnected and zero load.

Hi Zsde,

I tried all kinds of tricks there is out there.

Ended up talking back to the Growatt support and they recommended that I use ISP TOOL 4.3 which worked like a charm.

(if you need the tool, i've already attached it to my post on another forum - https://diysolarforum.com/threads/growatt-spf-5000es-firmware-update.35171/page-3#post-508910)
