I recently joined the forum and I'm excited to be part of the community. I look forward to contributing and helping others with their questions.

I have a Goodwe inverter, specifically the GW5048D-ES model, and I wanted to confirm if the Pylontech US3000C Lithium batteries are compatible with it. Can you please provide me with this information?

That looks like an older model that does not have CAN, so you need the GoodWe EzConverter, which is not made anymore...

You could run it in user define mode without battery comms, but that will void your warranty on the Pylontech batteries.

Thank you for your feedback, it is greatly appreciated.

Lead Carbon batteries with a configuration of (4x) 200AH could be an alternative option.

is this recommended?

That is very strange! Never heard of such condition. Leoch doesn't even mention the possibility of "comms". I run my system of 4 TD48100 packs without "comms", manage the charging strictly with the correct voltage settings on the inverter (user defined battery). I use the BMS communication ports only for monitoring.

Do you have a Goodwe?

They won't have nearly the life of a lithium battery. If you're in South Africa I'm going to say that they'll work, for a while where a while could be less than a year. In any case, lithiums will cost more, but will last a lot longer, can be discharged deeper, can be recharged faster. 

So it'll work, yes, but I wouldn't recommend it unless you have financial constraints.

Either way (acid or lithium) you'll have to set parameters on the inverter. So if you haven't, download the PV master app (or SolarGo) and check that it can connect to your inverter and allow you to change parameters. At this point don't save anything 🙂 just check that you could change parameters if you wanted to.

Thanks for the feedback.

if I go with lithium - I’ll have to replace the Goodwe inverter.

Why? You won't have comms between BMS and inverter, but you can still run a lithium battery by letting the inverter infer SOC from the battery voltage. 

Download that app and have a look. My Goodwe (which does have the CAN bus that was talked about earlier) has built in configurations for a number of lithium batteries (including Pylontech), a default lithium setting (which relies on CAN), and a self-define option which can certainly be used with lithiums.

Yeah, I checked the warranty wording, and it looks like I was wrong - it does not explicitly state that not using comms voids your warranty.

Presuming it is indeed a GW5048D-ES, it will happily accept the US3000C incl. comms.

If contrary to this you're  still keen to sell let me know, would like to upgrade my dads inverter (with two US2000s 😉

I can confirm it is a GW50448D-ES.

I’ve not made the Pylontech purchase as yet. Wanted to confirm compatibility first.

Current firmware has settings for Pylon US2000A/B not US3000c. There are also settings for lithium - 50Ah and 100Ah.

I’m I correct in assuming using the setting lithium 100Ah for the US3000c will do the trick?

 

 

That's a very old firmware, rather update (Goodwe support)

Don’t see any firmware updates for the GW5048D-ES on the Goodwe support site.

Any ideas how best to get the latest firmware?

Deal with Goodwe support. If you've done the WiFi setup correctly they can push updates over the Internet 

Thanks : I’ll log a ticket with Goodwe.

I am writing to seek assistance with establishing a connection between my inverter and my internet router. I have been struggling to get them to connect, despite following the setup process using EzManage.

Here are the steps I have taken:

1. connected my iPhone to the inverter's WiFi.
2. launched EzManage.
3. went to settings.
4. selected "Configure Wi-Fi quickly".
5. scanned for available networks.
6. selected my network.
7. entered the password.

However, after completing these steps, EzManage returned a message stating "send failed."

I have confirmed that the Wi-Fi signal is strong at the location of the inverter. I would greatly appreciate any ideas or suggestions you may have to help resolve this issue.

I need the Wi-Fi working in order for the Goodwe support team to update the firmware remotely.

Try do it manually...

1. Connect to inverter WiFi

2. Enter inverter wifi IP address into a Web browser (IIRC it's 10.0.0.2 or 10.0.0.39, if that doesn't work then check IP address in the user manual, or even in EZManage).

Hold on, EZManage??? If memory serves that's only for ongrid Goodwes (not for hybrids - ES Series). 

Another option, try PVMaster App...

Thanks Markus,

Happy Days- manual configuration worked. Inverter successfully connected to my home WiFi.

Now I’m struggling to get the SEMS Portal to work - plant is showing offline.

Logged a ticket with Goodwe yesterday to remotely update the firmware on the inverter. Hope I’ll be assisted today still.

Oh really, OK, my bad, didn't know there were old versions without CAN support

Hi @Archie1

I have the same inverter. At least the color is the same. If the serial starts with 95048ESU... I can assure you that the Pylontech US3000C batteries work perfectly. I have 4 connected. The only drawback is that you have to make a very simple CAN specific cable with RJ45 connectors on both sides. The cable from the Pylontech connection kit does not work well with the Goodwe, it gives errors of disconnection - BMS connection. The diagram was officially published by Goodwe for these batteries. I think it appears in a forum post, but if you can't find it, I'll look for it and post it.

On the other hand I tell you that the latest Goodwe Firmware is 1 2525/17 This is FW Version 1 2525 and ARM 17.

Regards

 

Hi Cef,

My Goodwe is 7+ years old - serial number 34048E……..

As Bobster advised - Pylontech lithium batteries will work, SOC will be maintained by inverter.

Yeah. Unfortunately, the Goodwe whose series begin with 3... would not, in principle, be compatible with the pylons through BMS.
Self-definition is always an alternative, but for the price of these batteries, from my point of view it is a risk.
If it were my case, I would try to evaluate the costs of the EzConverter as @P1000 suggested.
Look at this post:

I decided to opt for (x4) 100ah Lead Carbon batteries and had them installed this evening. Hoping for the best, anticipate their longevity.

To ensure efficient use of the batteries during load shedding, I have set the Goodwe in Back-mode. However, require assistance to confirm the configuration settings. Please refer to the attached screen grabs.

Your help would be greatly appreciated.
