Hi all
Last year in February I installed an SPF5000TL HVM-P Inverter with 2 x US3000 Pylontech batteries, and ever since then it has been quite the journey to get everything working exactly the way I wanted it, without issues.
I have only just recently achieved a state of operation that I consider to be optimal, where everything works to my satisfaction, including the Wifi data logger and remote monitoring.
To achieve that state of Inverter nirvana required many hours (days) of fighting with hardware, communicating with Growatt reps in China, and flashing firmware in my garage myself like a mad scientist.
Finding the right firmware has always been a challenge because there is no official repository of Firmware for Growatt Inverters and Growatt do not want us to maintain our own equipment, so we (the PowerForum community) have had to source the Firmware piece by piece through direct communication with various Growatt reps, over time.
I have decided that it is now time to release my full curated and organised library of firmware and information to everyone.
You will find the entire library here:

PLEASE NOTE:
Everything you find at that link is SPECIFICALLY for the Growatt SPF5000TL HVM-P Inverter.
Do NOT flash any other Inverter with those ROMs. Not ever. For any reason. Ever.
  I only use Pylontech batteries and some of the information might refer to Pylontech specifically.
  Growatt DO NOT approve of us flashing firmware to our Inverters over USB ourselves, or at all for that matter, and I have also been told that I should only be flashing firmware through some kind of USB emulator device.
I have personally never had a problem flashing over USB from a Windows 10 notebook without an emulator device, but I know what I'm doing and I'm methodical and careful.
You flash at your own risk. Both firmware, and in public parks.
  I do not have any Solar panels attached to my setup. It is configured as a pure battery backup / UPS solution. I have seen that other users of the same Inverter have had issues specific to Solar and I have very little knowledge on that sub topic. It is very possible that certain Firmware updates included in the link above may improve your experience with Solar, but I make no specific claims with regards to Solar and you should consult with other PowerForum users who have hands on experience with Solar connectivity with the SPF5000TL before you do anything crazy. DISCLAIMER:
I am providing this link, and these ROMs and tools, as a public service because I know how frustrating it is to not have this freely and easily available, and how hard it is to find this information and data, BUT I DO NOT TAKE ANY RESPONSIBILITY for what you choose to do with it.

I am not responsible for firmware adventures that go bad and result in the loss of life of Inverters because they were bricked because you forgot to charge your notebook battery before you started flashing or your cat jumped on the USB cable and pulled it out half way through a ROM flash.
I take NO responsibility for the consequences of your chosen actions, I am only the provider of information and knowledge. What you choose to do with it is on you.
DISCLAIMER ENDS
With great power (and a lot of ROMs from Growatt) comes great responsibility.
Good luck, and happy flashing
