Hi all.

I started with a job to upgrade batteries on a GOODWE installed in 2016 by someone else. It is a lightgreen unit I have never seen before. The unit has no CAN comms but there are 2x RS-485 ports only. The 1 RS-485 is used for the energy meter and the other one is ment to connect to a battery using a GOODWE EzConverter no matter what comms are used.

I have 3 Q’s

1. Goodwe do not have any stock of the converter here or in China. Will a general CAN to RS-485 do the job or do I need a dedicated GOODWE product? I see them all over the net.

2.If one can not mannage the CAN to RS-485 convertion can I try use the Pylons under ''users define"? If so, what settings will be good for the new Pylon 3000C models?

3.Lastly, I can not mannage to connect to the Inverter using PV Master so now I wonder if that unit may not have WiFi. If that is the case, how do one comunicate with it?

Any help will be welcome.

I will try to load a pick of the inverter.

Interesting, thats the same model I have, 5048D-ES but mine is from 2020.
Yours look like it is missing the network interface port.

This is mine, you can't miss the wifi module:

Jip Tinuva, that is the problem. My personal inverter is the same as yours. The one in question is a clients inverter. There are 2x RS-485 ports but no Can Bus. Users devine seems to be the only option for the battery but I will have to be carefull with the settings.

Ok it looks like the unit I have. Same serial break. I’m looking to also fit batteries with a BMS system. Let me know how you solve this one. 
looking to fit Pylon tech 3000 batteries. 
also can’t find a EZ converter to integrate the BMS to the inverter.

looks like we will have to set up on user define settings.

Hi 

Hoping someone can help with a wiring diagram to install the EZ Converter that i managed to find at last.

I have the older ES Goodwe inverter starting with serial number break 3-----.

Batteries is a single Pylontec US3000C.

The Manual is not to clear on the pin allocation to connect the RS 485 Cables from the converter to the batteries.

further more I will need to know the Dip switch setup on the Battery and the EZ Converter to get the BMS to function incorrectly.

Any further input would be appreciated.

Thanks

Hi Peet

1: I manage to locate a EZ Converter on Ebay and have it shipped to me from Germany, Try That.

Q3: I had the same problem when using My Iphone, for some reason. so with my I Phone i use the EZ Manager App. The PV Master app does seem to work with the Android app, the Above is on the older ES inverters with a serial break 3---

Hope this helps

Ronald can you describe exactly where you are getting stuck. Also to confirm you have the converter?

87

 

Hi 

Yup I have a convert that I managed to track down.

The connection between the Battery RS485 to the EZ Converter is what have a issue with.

The manual does not what color wire to terminate to what points on the junction block of the EZ converter.

secondly I would need to know how the dip switches need to be configerd on the Battery and the EZ Converter,

I have attached some photos.

Ha ha ha , @87 Dreamyou beat me in this race by 1 minute 😁 was just about to mention @Niel as usefull resource regarding this matter.

Morning

@87 Dream @dropkick

Ok I have read the info recommended but the question still remains. The cable from the CAN port on the battery to the EZ Converter.

I still cant see or understand what pin number (Color) on the RS485 plug and the point to terminate it on the EZ Converter.

The manual only reflect an illustration for the cable between the EZ Converter and Inverter. nothing indicating the connection layout on the EZ converter coming from the CAN port on the Battery.

Se attached photo 

Good morning Ronald 

I am experiencing difficulty submitting a reply from my laptop.

Just bear with me will respond soon.

Ok ,  so let us just make a summary of what I understand the context must be here :

1. You want to seamlessly integrate your Pylontech battery pack to your Goddwe inverter.To do so you require BMS communication between the two products.

2. It appears to me that that there are older Goodwe inverters that has limited BMS connectivity out of the box. Your inverter has this constraint. For this reason you have obtained the Goodwe EzConverter , which acts as a gateway between the Inverte'rs RS485 protocol and the RS485/CanBus protocol of your Pylontech. In fact you have already obtained the device.  This document https://www.solarquotes.com.au/blog/wp-content/uploads/2016/09/BPSeriesUserManual.pdf page 16,17 and 18 refers. According to the DIP switch setting it indeed support the Pylontech Protocol.

3. From some legacy legacy threads on this forum , it appears that the following electrical interfaces are required :
 3.1 RS485 From Inverter to AzConverter

3.2 CANBUS from EzConverter to Pylontech , however the https://portal.segensolar.co.za/reseller/docs/GoodWePresentationUpdated.pdf page 34,35  resource from @87 Dream may also suggest it could be RS485 . Either way we know the PylontechTech supports both.

4. If my above assesment and assumptions are correct , then we need to sort out the cable pinout requirements on both RS485 and CANBUS , at first from the EzConverter point of view. To do so  we need to identify the physical RS485 port  and the CANBUS port on your converter. The image of the connector  in your latest post suggest it is the CANBUS port (L and H seems to refer to CanHi and CanLo pins) .  Can you please send a photo of all the port connectors on the EZ converter?

5. Goodwe RS485  pinout and standard seems to be somewhat non-standard in that they provide separate RX485 and TX485 signals , suggesting a full duplex arrangement as opposed to a half-duplex standard . This should be no problem as both inverter and converter comes from the same bloodline . Fortunately the pinout on the RS485 connector is well documented. 

We have not solved your problem yet , but it is important for me to define the problem first.

Am I on the right track here ? , or do i misunderstand some of the context.

Note : a positive here is the LED indicators on the EzConverter , one for each side of the protocol conversion. This may be of great help during integration. 


Kind Regards

Hi Drop Kick

Thanks for your willing to help me with the issue at hand. please bear with me on this as most of your comments are above my Pay grade.

The situation is as follows: 

I have an older Goodwe ES inverter serial No: 3--------  that i have installed. I have it running on a Pylon US3000C Battery. Currently on self defined settings.

I want to get the Battery BMS to communicate with the inverter. for this reason I have managed to get the needed EZ converter that the manual shows is required to get this done. The manual is however not clear on the wiring termination required between the Battery and the EZ converter termination Block. (See Attached Photo)

From what I understand on the Dip switches and the document supply in your above comments is that the Pylontec battery is to be set as follows:

Battery DIP Switches as follows

Switch1: OFF, Switch2: Off Switch3: On Switch4: On, Switch5: On

 What I have read on this forum is that the EZ Converter DIP switches as to be as follows:

DIP switchs 1,2&3 are to be OFF and 4 and 5 are to be on see attached photo.

The only unknown is where to terminate the wiring on the EZ Converter.

For now I haven't wired it up yet as it is not clear on where to fit the wiring and DIP switch layout.

Im also not to clear if the plug must go in the CAN port or the RS485 Plug on the Batery.

 

Off the topic I must mention that when connecting the EZ Meter to the inverter I had some difficulty getting the correct info out of the GOODWE online help service.

But after +/-2 weeks and many frustrating discussions  It was found that one had to pair Green & Brown pin 2  and white/green to be paired with white/brown Pin 1,

On Discussion with GOODWE SA they admitted that due to the Age of the inverter that no one that had the understanding on how to sort my issue out.

A very frustrating ordeal. This is the reason I have now tried the forum to get this solved.

Thanks again

 

 

 

 

What I have noticed is that my battery only Has 4 dip switches see attached Photo

 

@Ronald W it is pathetic that a supplier can turn around and show cold shoulder without contacting good we support team. So here's the roadmap going forward : 

 

1 I will contact good we on you behalf and endevour to find the information . We also have a number of mail addresses of people at goodwe , which members said is quite helpful.

 

2 if that fails we will try our international guru @Coulombto find out if there ain't any answers on forums in Australia. Apart from guru he is highly connected to everything inverters ,albeit his forte is voltronics.

 

 

3 at the same time we will try to get the attention of @Neil and other EG. Byleveldt here on local forum . Niel has last visited here on 13 Oct , so he still seems to be around.

 

4 in the meanwhile you can also give images of the connectors on top of the ezconvert. 

 

kind regards

dropkick

Missing syntax

Oh and one more thing , while we going down these avenues, of course nothing prevents you by connecting your pylontech to goodwe using default safe charge and discharge parameters. If further help needed in this regard then members like @87 Dreammay be able to guide you, should you have not done so already.

 

So you can already enjoy the benefits of your investment.

Here with Images requested.

I have the unit up and running on self defined setting given to me By the goodwe sales rep. I just hope they correct as they could not solve my EZ Meter issue.

I have to open ticket with GOODWE myself and eventually get the issue sorted as mentioned before.

I will rather wait to have the correct info on hand before I connect the EZ converter as they not easy to come by. I would hate to blow it on an incorrect installation.

Mine I had to have shipped to me from Germany as Goodwe have non for Sale and chine say they no longer in production.

Thanks

Yes , I agree on inadvertant faulty connections  that can cause damage, in fact I am very tempted to tell you that L and H pins are pylontech canhi and canlo , but if not correct then risks very high.

Pylontech US3000 installation with Goodwe

 

If you look into Neil's thread you will notice he had the same issue as you. And he invited anyone interested to contact him.

 

Maybe you can ask the forum admin , if they can't send him a mail to try to get in touch with us.

I think "useful resource" is an apt description as I'm no expert with this technology but did spend hours figuring it out.  Maybe "sometimes useful" is more accurate.

Ronald contacted via DM and here is my reply for the record:

Yes, use the CAN port on the battery (looks like you have it on the RS port).

Attached are two extracts, one from the Pylontech manual and one from the Goodwe manual.  Some network cables have a cross over so have a look at the battery end to identify the colours (1 to 😎 and then connect the correct colours to the EZ Converter as in the picture. 

The dip switches should be 1 up and the rest down on the EZConverter and all down on the Pylontech.

 

Let me know if I missed any questions.

It may be a bit late, but maybe useful.  We also have an older model, 2015 I think.  

1. I'm not sure.  I got hold of an EZConverter and after much hassle got it work.

2. It should be safe to try as the BMS monitors the battery itself.  First prize is of course if the two can communicate so that the Goodwe can manage the SOC and charge/discharge rate before tripping the battery.

3. Our model has wifi and that model should also.  The first step is to get the inverter on the wifi network.  If you search for a wifi network, the inverter should appear.  Connect to it and set up the wifi settings using SolarMan.  Or at least, that worked for us 6 years ago.

 

@Neilthank you so much for the valuable and prompt response. I stand by my reference of you, but the correct English should have been  'Valuable Human Resource.'👍

@Ronald Ware you on track, or do need additional info?

 

Kind regards.
