Hi

Seems I have the same issue that @Tsa was having way back in 2020 - random trips and restarts. On restart there are no fault codes, etc. I did manage to catch one of these trips and it was a 04/20 error. 

I have the SPF5000ES with 2 x Dyness B3 batteries + Canadian Solar PV.

These issues only started happening when I added the 2nd B3 battery. The Dyness rep told me that both batteries have the latest firmware - based on the serial numbers. The inverter has the 67/68 firmware. 

Any suggestions / recommendations to remedy this issue?

NOTE TO ALL

We have now established that BOTH of the firmware updates that were provided to me by Growatt in China ARE required to get the BMS comms working correctly between the Growatt SPF5000 inverter and Pylontech batteries.

The two firmware updates they sent me are for two different things inside the inverter (Thanks to @Coulombfor taking a look at the firmware and confirming this):

• The ARM chip.
• The DSP.

Feedback from @Coulomb:   "So there are two firmwares in there, a TMS320F2809 (same DSP as most Axperts), and an ARM chip (Axpert Kings have one of these in the removable display)."

The firmware pack that I am providing to people who PM me asking for help contains both of those firmware updates, and they are both necessary to sort out all the BMS issues properly.

If you don't have both of those firmware updates installed, one of the symptoms is that BMS comms will appear to be working and there will be no errors BUT the SOC level will be stuck at 100% and the batteries will never get charged, which means that if you have solar connected it will never kick in and be used to charge your batteries.

And we have also confirmed that the firmware resolves the issues for a single standalone inverter and more than one inverter connected in parallel.

 

Hi ,

May i ask that you send me the firmware updates as well

Hello,
I used a cable with RS485 for a while and now I use a CAN cable. I noticed that there is a difference in data reporting on the 2 types of communication. More precisely, on RS485 I have never seen the battery with 100% charge, it was at most 98% and recently even 97%. Since I changed the cable to CAN, now it shows me SOC of 100%. So I think that communication on CAN is much better. For CAN I use a network cable (one to one) and for inverter LI at 05 and L052 at 36. DIP at battery 1-ON and the rest OFF. I have an SPF5000ES and 2 pcs US3000C.

Hi , thank you for this thread , i recently had the growatt 3kva 24 HVM inverter installed with 2x 200ah oliter gel batteries, the fan runs non stop since installation , according to the retailer this is a normal operation on this 3kva inverter , please advise if anyone else is having the same issue, and please refer contact details hoe to contact growatt to confirm.PS, no panels installed as yet.

Hallo. 

 

I am also three months having the same model and same batteries, I also experienced the same, I made calls and research from various people and dealers.

1. It was then concluded that Growatt 3kva has two fans which runs it, the noise depends on the load and are not suppose to stop provided the inveter is provided load.

2. Best option is to install it little bit far if the noise factor might be a challenge

 

3. I was also adviced to keep the place closer to inveter dust free so that the fan might not accumulate dust and affect the smooth running of the fan.

 

4. I personally have adapted to the fan noise though it was too irritating the first week of installation

 

5. (Subject to correction and further inputs)

 

 

 

 

 

 

HI HUYS GOT 5KW GROWATT INVERTER 1 X 4.8VOLT PYLONTECH BATTERY CONNECTED AS BACK-UP SYSTEM - NO PANELS - JUST WANT POWER DURING LOADSHEDDING. GOT COMMS CABLE AT RS485 AND NOT IN CAN PORT AS WAS SUGGESTED BY SILICONKID - NOW MY BATTERY SHOWS ON APP AS 255% FULL - WORKING GOOD ALL ROUND - DOES NOT WANT TO CONNECT WITH THE PROGRAM 2 ON LI - WHAT SHOULD SETTINGS IN GENERAL BE FOR ABOVEMENTIONED SETUP. BATTLING TO GET CORRECT PROGRAM SETTINGS FOR THIS INVERTER & BATTERY?

What app are you using?

BATTLING TO GET CORRECT PROGRAM SETTINGS FOR THIS INVERTER & BATTERY?

From my understanding the Li Protocol for Pylontech is 02. Not sure whether the LAN cable is a 1 to 1 or whether the Pylontech requires the cable to be made up. With my battery it's 1 to 1.

i'm using shinephone app. not very good i think - just gives you the basics.

 

Hi there. I have tried everything besides firmware updates. Would you mind to share on [email protected] please. 

You can use CAN with Li and L52 (not L02 !) protocol.

My 8x agm batties died so I decided to upgrade to a polytech up5000

Growatt SPF 5000TL HVM-P (build 500.07/002.03/null). FW that came with the inverter.

1. Switched Inverter to run off battery only. Disable A/C input and A/C output and PV input.

2. Go to setting 5 and select battery type = Li. Then select profile L02.

3. Now shut down the inverter (wait for the display to die) and switch off the batteries with the red switch

4. Connect the communications cable between the inverter and the battery

I made up a Cat5 cable as follows:

Inverter Side
Pin 1 White\Orange
Pin 2 Orange
Pin 3 White\Green

Battery Side
Pin 6 - GND White\Green
Pin 7 - RS485A Orange
Pin 8 - RS485B White\Orange

Cut the remaining\unused wires off

5. Connect cable on battery side to the port labeled - B/RS485
6. Connect cable on inverter side to the port labeled - BMS port
7. Set your Baud rate to 9600. Dipswitches 1 0 0 0 (1-ON 2-OFF 3-OFF 4-OFF)
8. Switch on your batteries followed by the inverter. Inverter came online with no errors and has been running smoothly for 2 days now
   
   The only problem I have now which has been discussed on the tread before is the fact that once the batteries are fully charged Solar is switched off. Yesterday which was a nice sunny day the system went in to overload error 07 and switched off when wife used the stove pushing the use to 2.6kw. I have 3.8kw worth of panels and the only thing I can think of is that max charge option 2 which is now being controlled automatedly and from what I've been seeing is being set between 10A - 32A is cause. So far I've not seen the system using more that 1600kw from the panels.
   
   I see user "ISS" reported fw 500.12 that might have corrected the solar disconnect issue. Has anyone tried is to confirm?
   
   Thank you.

Confirmed with Growatt that firmware 500.12 (SPF5000TL HMV-P) is the latest normal firmware as of 03-03-2023.
They do have a few others that address specific issues like Negative Value of power generation/ Daily restart of inverter to fix PV input/Continuing 01 warning ect to name a few. But these are only given out to fix specific issues as needed.

Both Growatt and Pylontech confirmed the above comm cable pinout as correct using 05 Li protocol 04
If 04 gives you error 20,04 - if already on firmware 500.12 start at step 5
1. Note down all your inverter settings
2. remove all loads
3. restart inverter
4. update firmware to 500.12
5. restart inverter with no load - insure it starts up normally
6. reset inverter to factory - Press UP+Down together (Display will change to code 00) Press enter and adjust to 305 (up 3 enter, up 5) Press enter twice and wait for long beep and unit will spin up.
7. restart the inverter and set all your settings previously noted down in step 1 - if it happens that you get a error (LED is light) as soon as you set 05 Li 04 - wait 10-15sec for to comms to establish.
8. Restore loads

Setting 05 LI 02 will also work but will "cap" your max charge current to around 32Amp which intern will limit you PV input to around 1650watt - this is because 02 is close enough to 04 for Pylontech and the inverter to communicate but not fully.

Since factory resetting my inverter after updating to 500.12 my PV is no longer limited and I'm able to fully carry my loads and charging my batteries at the same time using 05 Li 04 on a sunny day.

 

Hi Everyone

I have the following setup:

2 x Growatt 5000TL

4x Pylontech 3000c Lithium's

24 x 335w Panels

I am using the BMS setup on the Growatts (setting 5 = LI then 36 = 04) Does anyone know on setting 36 (apart from setting 4 or 2) whether there are other Pylontech configurations) I have tried to use the USE setting fro setting 5 but then you cannot use the Shine app to manage the batteries.

Thank you in Advance

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

What exactly isn't working\showing on the Shine app?

When I communicated with Pylontech earlier this year they insisted on using Li 05 L04 only. From what I could gather that is what was tested between them and Growatt since Growatt on the TL only provides an RS485 port so if your using the cable I have above you should be fine.

That being said you could try CAN. On the inverter side, the battery comm cables remain in the RS485 port but on the Pylontech you would swap over to the CAN port now and use setting Li 05 L52 on the inverter. Take note that your comms cable pinouts will change now to:

Inverter Side
Pin 4 CAN-H
Pin 5 CAN-L

Did a quick Google for the 3000c manual it appears to be the same pinouts. So make up a new cable with ONLY these 2 connected on each side.
Battery Side
Pin 4 CAN-H
Pin 5 CAN-L

You can download it from here Option 9 - https://www.amosplanet.org/firmware-download-for-off-grid-inverter/

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

Hello,

I need an installer that can help me with an existing Growatt and Pylontech setup. Somebody with experience with a parallel Growatt system. 
 

In Pretoria please. 
Thanks

Hi Guys,

Please can I have the firmware updates experiencing similar BMS issues. [email protected]

Thanks

Hi All

I have the following and just can't seem to get growatt or Shoto to assist.

Growatt SPF 5000TL HVM-P with latest firmwares loaded.

2 x Shoto SDA10-48100 (5.12Kwh) Batteries

Batteries are connected as per manufacturer including the RS485 cables provided for BMS communication between batteries.
According to manual RS485A port on 1 Device and RS485A Port on second device.
Dip Siwtches are set to 1 on and 5 on on second device.

Straight RJ45 cable is plugged in on CAN port on Battery with dip switch 5 and on BMS port on Growatt inverter

One advice I did get from Growatt was that I should use RS485 with Option 36 set to L07.

I have done this and it appears that it is talking as I am not getting error 20. LIT icon is on next to battery. Only message now is warning 04. Low battery. Shine server is reporting SOC as 0%

According to SOC lights on batteries themselves = 50%-75% charging.

I am not sure if the comms are correct or if I am missing something.

Any guidance or advise on what to check will be greatly appreciated.

 

Hi @Robert DT, did you ever get this resolved?

Good day, 

I am running the Growatt inverter SPF 5000 ES with Pylontech battery UP5000, and 5 x 540w Solar panels. 
The inverter was running fine without any issues for the first 10 months, 
Since the past 2 months, the inverter keeps on tripping and restarting during the day when the battery is almost full. The random trips/restarting can happen 3 times in an hour.  

If I switch off the PV input, then trip stops. 

Please could kindly advise of any suggestions or recommendations to resolve this issue. 

 

Sabza,

From what you say, it sounds as if the string from your panels is for some reason producing a higher voltage than what your inverter can handle.  I guess your 5 x 540 W panels are all set in series, but even then, the theoretical voltage would be  about 250 V DC  2.700 W 10.6 A and the Growatt SPF5000ES can take as much as 430V and 18.3 A....

There is however a fact that PV panels can produce more power than their specs during these days in Spring when the sky is clear but temperatures are still low, but there is no way they can produce such a difference.

Are your panels in series?

Good day,

Yes the panels are wired in Series.
