Hello,

Does anyone know if the "EG4 LiFePOWER4 Communications Hub" works with SUNGOLD POWER inverters?

I have an SP6548 inverter with 3 Eg4 48v 100ah batteries. I would like to create a closed loop communication between batteries and inverters


Is there a communications hub that works between SUNGOLD power and EG4 batteries?

Thank you for any help you guys can give.

Isn’t sungold a Voltronic inverter?
 
Is anyone able to test to see if it works? It would be great to create the close loop communication.

That would definitely INCREASE sales at signature solar if it can work with SUNGOLD LV6548
 
Hello,

Just wanted to check in to see if ANYONE has the EG4 hub and attempted communication with SUNGOLD power SP6548 or any other SUNGOLD power inverter?

I have an SP6548 inverter with now 6 eg4 LIFEPOWER4 batteries 48v 100ah. Would like to use closed loop communication
 
I ordered a hub today mostly just to see the info on the screen, but I can try to hook it up to one of my LVX6048's when I get it. Not the same unit obviously, but it is Voltronic and probably has the same general protocols.

Hello,

Thank you Rich. I know that will Prosser in his unboxing said it has the same firmware as lvx6548, but who knows. It's ALWAYS something when it comes to compatibility. It would be amazing if it worked. My family has it's setup in Puerto Rico AFTER Hurricane Fiona last year(2022) in September.

I will wait for your response.

? hopefully it works ?

Hello,.

Did your hub work with the LVX6048 inverter?

Lol! Totally forgot that I bought this to be honest. Ironic that I got a message from you and an email asking "how did we do" from Signature Solar on the same day :p I just installed it (pretty easy) to the batteries, but I have to make an RS485 cable. Let me work on it and I will try to get back to you today.

Thanks for the reply. Hoping it does work. ?
 
Using the solar power app, the batteries are showing almost 2V higher on the LVX6048 that is hooked up to the comm hub (54.2V vs 56.3V). My two units are completely independent (not parallel). When I put a big load on the inverter (my AC is 2500w), the voltage appears much lower than the non connected inverter (54.2V vs 50.7V). I only have 1/3 of my solar array hooked up, so the most power I can generate is about 4kW, but with that I am currently dumping about 50-60 amps into the batteries, which is very gentle I think (10a each?).

I hooked it up. It didn't blow up which is good, but I honestly didn't see anything magical happen. Is there something you want me to test?

Nothing to test other than to verify that the hub communicates with the LVX6048.

I have a SUNGOLD power SP6548 and firmware is same as Victron from what will Prowse stated in review video.

Sounds like it communicates from what you are saying... Is that correct?
 
It looks that way, but I don't have anything earth shattering to report. If you can think of something for me to test I will try it. I really like the hub just to see all the details on the different packs. I am pretty happy with the values, especially after two months of use with the solar panels. Now I just need to get the rest of the panels hooked up.
 
Hi,

I wanted to have "closed loop" communication between the LiFePOWER4 batteries and sp6548 inverter for more efficient charging and discharging of batteries.
 
I have an SunGoldPower 10KW SPH10K48S inverter and a rack of six EG4 Lifepower4 batteries. The EG4 Communication hubs Inverter protocol is set to Pylontech and the hub correctly provides the battery data to the inverter (the hub sends the data as if is one big battery). If you monitor the battery RS485 bus you will see that the hub polls the batteries (all 15 that could be connected) and receives the reponses for the active batteries.

The communication between the hub and the inverter is:

Inverter to hub: 7E-32-30-31-32-34-36-36-33-30-30-30-30-46-44-41-38-0D
Hub Response: 7E-32-30-31-32-34-36-30-30-44-30-31-32-45-31-30-30-41-38-43-30-30-39-43-34-31-33-38-38-43-30-46-39-42-31-0D

Inverter to hub: 7E-32-30-31-32-34-36-36-31-30-30-30-30-46-44-41-41-0D
---no response
Inverter to hub: 7E-32-30-31-32-34-36-36-32-30-30-30-30-46-44-41-39-0D
Hub Response: 7E-32-30-31-32-34-36-30-30-38-30-30-38-30-30-30-30-30-30-30-30-46-43-32-31-0D

Can someone explain how to decode this information?

Just to clarify, is the hub reading the battery information and displaying it on the screen, or is the sequence above what it is displaying?
