Hello Jaxon. Any update regarding the idea of mixing Pylontech with a diy pack?

The January release is 040/041 06 1.04 I just flashed it meanwhile.

I hope I am not wrong but the firmwares nov2021 and jan2022 are 4x.06. The november one is 40/41 06 b29 I do not remember exactly the ending for the january release but it may be 7.

I can confirm the MPPT current limit is now 22A. However the inverter has another behavior on my setup: Both FW posted (november 2021 and january 2022 have 22A limit on MPPT. I downgraded to november version to check if there are different behavior and I did not observed any. What I dislike is, when there is 4.8kw from PV and you connect load 4.9kw, the PV power drops to 3.6-3.7kw which is annoying. I have to wait until the PV power is over 5kw and connecting additional load up to 100% will not make the PV power to drop. The PV throttle is still slow. Let's say you have 1.5kw PV power instant and 1kw load. Some power goes to battery. If you turn off the load, the PV power is not transferred directly to battery. First, the PV throttle goes down and increase afterward as the charger demands the power. Probably is the charger behavior. (I do not remember to observe this on the 05 version but I have not checked especially)

Hello Sorry for missing the notifications. I posted the files on another solarforum. Anybody can download from there and get more information about the fw upgrade process. Probably the link will be forbidden by the rules of the forum. (copy the text below and paste it the browser address bar, remove the spaces before and after the dot, most probably an account will be required for downloading the attachments) diysolarforum . com/threads/growatt-spf-5000es-firmware-update.35171/post-479197 I recommend, do not post emails address public. You will reach on the spammers list. Just read a little, search on other forums and download the files yourself.

A have performed FW upgrade from 040/041.05 7. 01 to 06. 1.04 using ISPTool v4.30 and the guide from https://www.elleyhillpower.co.za/pages/growatt-spf5000es-firmware-upgrade Since the guide is very explicit, I wish to mention. Perform MPPT fw upgrade first if wanted (F030... file) and the inverter fw upgrade after that (F2809... file). In between, the inverter had a strange state on the screen (was mentioned by other user here). I did not check if it works properly. I've got the files directly from Growatt support. I did this upgrade in order to get 22A from the MPPT since I have seen it is limited to 18A. I will observe in the next days if my system will reach closer to the 6kwp installed since from the installation my sistem could not exceed 5kw. Is the factory reset mandarory after fw upgrade? Does anybody knows what changes should we expect from these fw upgrades?
