Yes, using influxdb and grafana on a raspberry pi to collect and report all the data and an 8-port relay board to control consumers by PV power, timeslots, etc... precondition is to flash a custom firmware to the shine-f´s to send all the data to a specific IP which in my case is the raspberry...

there is no setting to prevent charging from the PV except you use battery communication and the BMS tells the inverter to stop. don´t pull your hair everytime, you will look bald afterwards with a wound on your head

Use the one included in the inverter package and you are fine... The issue is that you often don´t know if the USB cables are customized so the best way is the OEM cable.

Hi Tomjay, same behaviour here. I have 3 of them in 3 phase constellation but from time to time the inverters are not going back to grid and starting the bypass. I assume this has to do that the grid Voltage or frequency is not synched with the output of the Inverters. IOn the inverter which is...

@Jeromebricolo I have the latest firmware on my devices but I have the newer hardware version so my firmware is at 067 and 068 not the latest for the old hardware version 0.40/0.41. @dozynsleepy I can tell you bypass is working 9 days out of ten in average. on the day it won´t work it can...

no issue. The only thing you really have to take care of is the short cut voltage of the panels it never should go above he 450V. I have paralled 2x4kWp with peak currents up to 23a and the inverters can deal with it perfectly. In winter I have much better results from the mppt as it will not...

It´s an issue with their SBU mode. As far I investigated this is not addressed by any actual known firmware. It seems to me that the frequency from the input is not correctly synched to the output in SBU mode. Once this situation happens the inverter refuses to switch back to AC which causes...

maybe a result of bad wifi connection to the shine-f´s...

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...

how much kW is your battery rated?

Update it by yourself is quicker and easier than ask Growatt for it. Why: The old firmware are buggy, even on the latest hardware versions Growatt produces. There are several minor and major issues known with the shipped firmwares that´s why a firmware update makes totally sense...

he used a macbook and emulated windows. I told him to change to native windows and he got it somehow managed to flash the firmware.

ok but you will not have 20% decreasing SoC over night with 34kWh capacity, right? I assume that the OP has a slightly smaller battery capacity...

I have a similar firmware flashed to my shine-f sticks to transfer all data to an influxdb to control the whole PV and switch relays based on conditions. Here are more details (unfortunately only in German but google translate will help you) https://pilling-sonneberg.de/shine.html

@sydzz you can use any voltage and voltage type you want up to 3A/230VAC. your manual will explain everything around page 11. Yes P12, P13 and P21 have influence how and when the dry contact uses which contact situation, this is also explained in the manual. you will not measure a voltage if...

BTW the new 113 and 114 firmwares are NOT compatible with older versions of the inverter and vice versa. So be aware not to mix firmwares with older inverter hardware versions.

in SBU set 2A or higher for P11. Your battery will not get drained anymore as the inverter should charge as soon P12 is reached. Don´t worry if the inverter will not reliably switch to grid. This is a known issue of the growatts and most people who are using SBU are suffering from this problem...

no the 067 is not compatible with the older 040 devices.

did you read through the flash instructions provided with the firmwarefiles and how do you power the inverters while flashing?

yes, since last year I use the dry contacts to connect and disconnect grid to the inverter as the old version 067 and below have issues with phase synchronisation in SBU and SUB mode. since I use the dry contacts I run the inverter with UTI and it behaves exactly like SBU should.

if your battery is not providing enough power the voltage will drop down and the battery or BMS will shut down the modules. Each inverter can draw at full power around 100A from the battery. I assume your tiny 14kWh storage will never support such a load. You have to consult first the battery...

Back to the initial post. the inverters share their settings via the grey communication cable. Once you decided for your setup you have to connect the inverters via the grey communication cable and in some constellations also the green power comms cable. After this is properly done (check the...

three phase setup ist the worst condition to choose. First of all in the three phase setup all three inverters have to be online at the same time if one of the inverters has an error or is not communicating anymore all three will reject powering the loads properly. If you are not in need of a...

best way is to go with a BMS with CAN commuication. you at least use RS485 as I see from parameter 36. most of the settings are managed in that case by the bms and manufacturer sets the batteries up to work perfectly for longer period of times. P12 is the setting when the inverter switches back...

"ate"? depends on your battery setup. The BMS should have the manufacturer settings and these settings provide basic information to the inverter about voltage, current, power etc.

which firmware are you using?

Use the Pylontech with LI 52 value in the Growatt settings and the BMS of the pylontech is taking control of your chargings if the packs are properly wired. never had any issues with mine, but as explained before if the voltage drops due to high loads the packs might go to an error state.

I assume it was a wrong setting from factory setup. There is a secret menu you can access by entering the key 111 which unhides P27. This parameter sets and/or restricts the power/capacity of the inverter. Could have been set to the wrong setting from factory settings... With which firmware was...

ok if you checked everything else then it must be the driver or your windows pc. maybe try to use another laptop...

for all out there with issues: you need to flash the correct firmware files for your model. The only indicator for the right firmware file is the firmware version on your device for end users/customers by today. Growatt might have more details but the label on the side of the inverter is not...
