Hi everyone,

Can somebody help me where can I find Firmware "F2809_GW500.07_20191227_B." Instead I have found F2809_GW500.09_20201029_A.bin.

I do not think it can work for SPF 5000TH HVM model.


Best is to contact Growatt support if you want FW specific to your inverter. Don't just go downloading the firmware from the net because you are going to end up with a damaged inverter 😂

Arya, best of luck with Growatt technical support, ( it does not exist) my experience is the following, contacted them a few times, still waiting and waiting, eventually I gave up. Also have issues with BMS coupling, eventually I decided to just run the system without BMS.  contacted both these mails  [email protected]   and  [email protected]   and as I said above still waiting.
