Hi and awesome that you have a direct contact to the guys. from my perspective the 06X versions are suffering from a phase sync issue while transfering to the grid.
with the original shipped firmware at the 06X which is 06X 01 1.04 the issue seems to me that the inverter checks the phase sync before switching over to grid. only if the phase is synched correctly or is in a minimal deviation the inverter switches over to grid. I assume that the inverter only once synches the phase to the grid when the grid is switched on and after that it never checkes the correct sync. So at the previous mentioned firmware there is somehow a procedure which prevents switching to the grid if the phases are not syncronized.
There is a group of people I supported with updatoing firmwares here in Germany and I got feedback for the 06X F4 A.27 firmware. This firmware behaves a little bit different. It seems that the checking procedure for the phase sync is not present anymore in this firmware. I got feedback from other owners that this firmware switches at least back to grid but has the issue that through the non-existing phase check procedure the inverter switches "hard" to the grid which leads to all connected consumers switch off when the phase sync is not properly done.
My assumption is that there is a major issue with the phase sync in the firmwares which leads to really short power outtages or prevents the invertercompletely to switch back to grid at reaching P12.
I still use both of my parallel connected inverters with my hardwired solution to switch the grid on via the dry contacts. This solved all the issues for me with the inconsistend switch back to grid. As the power relay I use is only active an connects the grid when P12 is reached exactly at this point the phase sync happens and there never had been an issue here for the last 8 months. However the SPF inverters have those issues at least in the 6X hard- and firmware versions and Growatt would do good to solve those.
if the BMS is able to talk with the pylontech protocoll and you want to use CAN as preferred communication L52 is the setting to go with.
Thank you @kirkdis
I have described the problem to them and they sent me this video showcasing that there is not any actual problem... But i think this is 113/114 firmware on the video. I will check and let you know.
I uploaded the video in .rar format because you cannot upload a video file here. Let me know if you can unzip it. Thanks!

I described the issue also several months ago to their german support representative without any solution.
Regarding the video, here are my thoughts: the inverter in the video is not a SPF5000ES. The only thing which seems common to the SPF is the same display unit.
the issue with the unreliable switch back to grid happened for me in 2 out of 10 cases (the dry contact seemed everytime to switch correctly!). that means in 10 days where the inverter needed to switch back to the grid 2 days where not successful. My assumption is that the phase sync from the inverter drifts away over time from the grid phase. Only when this is the case the inverter is not able to switch back to grid or hard switches back to grid, this depends on the firmware as there are different behaviours in each one. This video is not proofing that their crappy firmware is working fine. (test condition and only one switch back)
Under test conditions I can switch 100 times back an forth to grid in SBU without any issues. I can not check what they programmed in their firmware but for my experience with the SPF inverters the longer the inverter is connected constantly without interruption to the grid the more often it happened here. In SBU the inverter is usually constantly connected and this seems to benefit the cause.
You can sort the Growatt support engineers in two groups: group one doesn´t have any clue about the technology, group two is not able to communicate with the customers properly and misunderstands most of the details.
And exactly this is the biggest issue Growatt is facing and leads to these weird explantions in the provided video...
As I use my inverters not anymore with a constant connected grid I assume this is and was the solution to solve the isse with the switch back.
Due to the fact I use uti as working mode as soon the grid is available the inverter makes the phase sync and switches over to energy provider power. This is for me the most reasonable explanation why the external switch works great and the internal switch is unreliable.
You are right, they cannot communicate well and i think they don't fully know their own technology...
Could you give us a cost estimate for your solution with the power switch / dry contacts?
It´s not that much. for the dryport I propose to use a fused circuit breaker depending on the cable diameter. The contactor/relay for switching has to be rated higher than the max input power of your inverter or the sum of the inverter if it is a multiple setup (I use 63A rated one).
So the hardware is only a small amount. the relay you can get from 40€ starting. the breaker is only a few bucks and then you need a few cables, that´s it....

Hi guys new here,
I am having issues with my parallel connection between my two inverters.
Is it imperative that the inverters are setup on the same firmware?
long story short,
my batteries aren't charging and I can only power the house via grid bypass and the inverters will not work in parallel without battery connection but the batteries will not charge because they are essentially dead (zero charge) I am fearing the worst atm.

Growatt SPF5000ES has bulk Voltage limit up to 58.4V, does the new FW unlock this limitation ?
Please Confirm
Please Confirm
please send me the firmware you used.
@onzifonzi for firmwares there are other threats already in discussion here but to keep it short visit https://www.amosplanet.org/firmware-download-for-off-grid-inverter/
@zipoman no u have to use different firmwares for the 3500 and the 5000 version as far as I´m informed but no warranty as I never had my hands on a 3500 version

The drainage from 100% is completely normal, the Inverter command and control is powered only from Battery or from Utility, to avoid micro charges/discharges that are detrimental to the LiPo battery because solar is not reliable they implemented a range, will charge up to 100% and will stop charging, because the inverter command and control section at that point is powered from battery will slowly discharge the battery down to 95% ( the power that is drained from battery is around the specified power written in the book when IDLE 60-80W/h ) where the inverter will start to charge the battery back to 100% and so on, if there are periods when there is not enough solar power will drain the difference from battery, as long as the battery is under 95% from the initial charge to 100% and there is enough power to drive consumers and to charge the battery the inverter will try charge the battery back to 100%.
Hi,
I would like to update my SPF 5000 ES due to the loud fan noise.
My firmware version are 067 01 104 / 068 01 104.
On https://www.amosplanet.org/firmware-download-for-off-grid-inverter/ are 2 version of firmware for that.
Version 1: F2809_SK067.F4_20221027_A.bin / V103_SK068.F4_20221027_A.bin
Version 2: F2809_SK067.03_20230630_A.bin / V103_SK068.03_20230630_A.bin
I read here that the firmware 27.10.2022 (version 1) could fix my problem with the fan.
My question is will the firmware from 30.06.2023 also fix my problem with the fan?
Has anyone experiences with the firmware from 30.6.2023 (Version 2)?
Which version should I choose?
Thank in advance, qwas

I would think they would both fix your problem, I have used the F4 on a friend's machine to solve the problem as the 067.03 was not around at the time, I have another mate with fans running high speed and will go sort his machine out in a week or so But will use the latest 067.03 as I'm told it also has the fan speed update sorted
hi there, i confirm .03 fixes the fan speed control. mine is silent with this update. no issues so far.
Hello,
I am having the same issue!
can you plz share how did you solve this problem?
My two cents, some setting with battery or BMS is telling inverter to not charge. Inverter does not have a great finetune control of PV and by not having anything to do with extra PV power, it disconnects.
Does it happens under bigger AC loads or with battery at lower SOC? cheers
EDIT: looked again at the video, battery icon is flashing, doesn't look the inverter is configured to talk with BMS in lithium mode. If it is, check the SOC in growatt and see if it matches the battery.
If not connected or not working, check the float voltage
Bina, after installing the new firmware, is the inverter any quieter and by how much?
Is the firmware used F2809_SK067.F4_20221027_A V103_SK068.F4_20221027_A.bin?
How to restart the inverter at the end of the firmware loading? Thanks for the answers and greetings from Brežice!
Bina, ali je po instalaciji novega firmwarea inverter kaj tišji in za koliko? ali je uporabljen firmware
F2809_SK067.F4_20221027_A
V103_SK068.F4_20221027_A.bin ?
Kako se restarta inverter na koncu nalaganja firmwarea? Hvala za odgovore in pozdrav iz Brežic!

What the new firmware does is preventing the fans to be most of the time close to full 100% power. Now they do variate speed according to device load. That makes much more sense, but if you keep your device with high loads, it doesn't really help that much. My opinion is that it worth it the upgrade as no one (in normal condition) run the inverters all time close to full load.
To restart, after all the upgrade, i turn it off, disconnect mains, solar panel and in the end the batteries. Give it two minutes and reconnect in inverse order. Is a common recommendation to return the device to factory default settings, but i may confess i never did it and never had any trouble.
Hi All, I am new to this forum hoping that someone had the same issue as me...
I have 2x Growatt SPF5000ES (both has FW Version 040.04 and 041.04). I use to have 2x Pylontech 3000C batteries. Everything ran fine for almost 2 years when I added 2 new batteries and the old batteries got replaced. All 4 of the new batteries are Pylontech 3000C.
My inverters will randomly complain about BMS communication error (Error 20 and Error 4). It was worse when I had only 2 batteries (with restarts between 1-5 times per day). With the 4 batteries this is happening 1-3 times per week.
My installed put the inverters on US2 mode, but I reverted to BMS since I believe that is the better setting... Will upgrading to the newer firmware sort this out? Anyone else that had a similar issue?
Thanks!

04 warning means low battery. When battery voltage is lower than 44V, it will report this warning.
20 warning means BMS communication error.
Here the problem, your battery voltage is too low until it shut off the BMS in Pylontech which results in BMS communication error.
Due to how growatt programs the charging mechanism of BMS+LI communication more, the actual SOC will drift off as time passes.
I am amazed that your pylontech actually able to run for almost 2 years before shitty Growatt 95%-100% charging mechanism causes your pylontech SOC to be out of whack.
To solve it, you will need to top re-balance your pylontech...........individually if possible.
Pylontech is mostly using 15 cells, therefore use USE mode, set CV and CF at 51.75v (3.45v each) and hold it there for the balancer to work its magic? But there is only passive balancer in pylontech........if you know how to retrieve the cell voltage from the pylontech via canbus, it will be easier for you.
Good luck in top re-balancing all your battery pack.
