Hi Coulomb Are there any firmware versions (I have an MPPT Max E 11kw 73.06 and 12.21) which allows setting of % for Pylontech that you are aware of? Thanks in advance Jeff

It looks like there is a new firmware release for the Growatt spf5000tl hvm. https://www.amosplanet.org/firmware-download-for-off-grid-inverter/ https://www.amosplanet.org/wp-content/uploads/2022/05/F2809_GW500.13_20230217A.zip

Thanks Neph. Can you confirm you used this and your growatt is an spf5000tl hvm-p as it doesn't mention the -p. Thanks

Hi Neph. Do you have the latest firmware 500.12. If so could I have a copy please?

Hi Has anyone got a later firmware for the Growatt SPF5000TL HVM-P than 500.12? Also can anyone confirm if 500.12 definitely causes Fan Lock problems.

Can anyone confirm the 500.12 causes fan lock problems.

Thanks fatboy. I have upgraded to version 500.11 and same problems. Can you confirm if 12 does cause a fan fault or not? Thanks

@SiliconKidHi Silicon Kid. I have 2 x growatt spf5000tl hvm-p inverters and 6 pylontech us2000c batteries. If li-02 is selected i get max charging current of around 20A enough to charge 1 battery really. The firmware is version 500.07/002.03/null. If I upgrade to firmware version 11 does this fix the charge problem ?

I have 2 x Growatt SPf5000TL HVM-P and 2 x Pylontech US2000's. Communication via BMS. I noticed a few weeks ago that there would suddenly be a loss of power for a few seconds totally randomly. A complete shut down and restart. Occasionally I could capture on one of the WIFI dongles a sudden drop in output volts from one of the Inverters. I decided to switch to PVKEEPER to see if I could see what was happening in real time. Since removing the WIFI dongles which is necessary in order to plug in the USB, there hasn't been a drop out. It seems to me that the BMS is being interfered with by the WIFI dongle. Perhaps there is a common routine in the firmware that's handling both the BMS AND the WIFI? Has anyone here had any further response from either Growatt or the battery manufacturers?

Hi all. I have two HVM-P in single phase parallel with two Pylontech US2000 batteries. Setting LI 2. haven't had data logging loss of data. However, I have had random shutdowns for a few seconds and have been unable to identify the cause. So I removed the dongles and used pvkeeper to try and see in real time what was happening. So far no shutdowns. How about the possibility that the dingle commsare interfering with the BMS comms?
